2016 - 1997 = 19 YEARS!


    The first articles of our website BIOMETRICS were published in 1997. Thus, in November, 2016 to our website 19 years are executed... Regular readers of our website sent us the congratulations what we are grateful to them for. Concerning the scheduled anniversary of the website we prepared the next article "We Compare Averages, as well as...", useful to readers . In it the advantage of comparison not only group averages, but also comparison and other parameters speaks to researchers in medicine and biology. In particular, comparisons of dispersions, check of normal distribution, comparison of correlation coefficients, regression coefficients or vectors of group averages, comparison of groups by multidimensional methods in which supervision are described by different signs, etc. Details of these new comparisons are followed by formulas, tables, schedules. Also speaks why lack of normal distribution means availability of interrelations of a sign with other signs. By tradition of the scheduled anniversary of our website, in two last articles also other very useful links are placed...

Compare Averages, and well as... V. Leonov

     To researchers in medicine and biology very big benefit is brought by comparison not only group averages, but also and other parameters. Such new comparisons are checks of equality of dispersions, correlation coefficients, regression coefficients or vectors of group averages, comparison of groups by multidimensional methods, etc. In article the great value of detection not of normal distribution of a sign is explained. It is shown that not normal distribution of a quantitative sign, means availability of interrelations of this sign with other signs. What is the major argument according to the formulation of the list of check of interrelations of the major signs of the conducted research. Specifics of other comparisons are well illustrated by different schedules, and also availability of the list of references from 98 books and articles useful to this subject. And more than a half of them have references to available these editions on the Internet. By tradition of the scheduled anniversary of our website, in two last articles also other very useful links are placed...

Shramko Svetlana Vladimirovna's REVIEW, associate professor of obstetrics and gynecology of DPO GIUV, Novokuznetsk, of cooperation with BIOMETRICS. "I express huge gratitude and gratitude to Leonov Vasily Petrovich and his colleagues - to staff of the BIOSTATISTICS center for effective and fruitful work.... In my opinion, the most valuable is the possibility of training in statistics, the offered format of communication allows not only to discuss the received results, but also together with it to develop, raise to the author of dissertation and to be improved to some extent. Having experience of writing of the master's thesis, understood - as methods of statistical processing of material which I own as a little I know are primitive!

REVIEW Harutyunyan MR, dentist, Saratov.
Hello, dear Vasily Petrovich! I want to thank you and your colleagues for his professionalism, personalized and attentive approach and high quality execution of the work! ... Prior to the cooperation with Vasily Petrovich, I tried to figure the statistical methods of analysis and read more than one direction. But the more I read, the more I realized that I do not understand anything. All my ideas about the statistical data processing included the calculation of averages, standard deviations and compared. I could not imagine that there are such interesting analysis methods such as cluster analysis, analysis of the conjugation tables, correlation analysis, logistic regression!

Percent - statistical analysis? Or percent - the arithmetic analysis? V. Leonov.

As well as it is necessary to the associate professor, I have degree of the candidate of medical sciences, the dissertation is defended in 2011. Working on the master's thesis, statistical data processing was the most difficult for me. Being trained in full-time postgraduate study, I attended 5 classes according to the statistics provided by the program of training of graduate students. Classes were given by whether the student of technical college, whether the young teacher who constantly looked in the abstract and could not understand an essence taught by it, especially also trained could not understand this essence. Applied value to the gained "knowledge", I did not find. (further...)"

Rostov state medical university. - Rostov N / D.: Publishing house "Akademlit" (IP Kovtun S. A.) 2014 of 414 pages of ISBN 978-8-904067-03-8.

In the monograph results of profound statistical analysis of retrospective data from protocols of openings of the persons who died of brain strokes (1135 cases) in years high (2000-2002) and low (2008-2010) of solar activity on the example of Rostov-on-Don are brought and analyzed. The next maximum of solar activity observed now staticizes need of collecting, processing and judgment of the new scientific data promoting forecasting and development of preventive measures for decrease in diseases at the different groups of the population caused by magnetic storms when strengthening activity of the Sun. It is noted that in forming of vascular diseases of a brain cumulative influence of multiple risk factors is traced.

Thomas A. Lang, Michelle Sesik. How to Report Statistics in Medicine. Annotated Guidelines for Authors, Editors, and Reviewers. Trans. from English. VP Leonova. 2016 - 480 p.
The relevance of this edition is very high. Still in biomedical articles and dissertations published by the mass of statistical nonsense, as examples of "statistical self-satisfaction" and "statistical make-up." For example, in the two theses, completed in 2014 and 2015. Altai Medical University in different specialties, but in a completely identical descriptions, consisting of 94 words, the following is written. "These data were statistically processed using Microsoft Offis Exel program 2007. The significance of differences between mean values ​​was determined by Student's t test of significance (t). Normal distribution in the groups was assessed by the Shapiro-Wilk ". Further reported on using the Mann-Whitney test, etc It is obvious that under Offis Exel authors implied Office Excel. It would be difficult to guess about it, if the authors wrote Offis Exul. Conclusion: Both of dissertation, as well as members of two dissertation councils, do not know much, including those described in this book. For example, do not know what is in Office Excel package no criteria Shapiro-Wilk and Mann-Whitney. This book teaches is right and good to describe and understand the results of the statistical analysis. Therefore, researchers have become more qualitatively perform statistical analysis, getting the right technology patient care. What the result will be to reduce the mortality rate, as well as the cost of treatment.

Previous editions of the original of this book was published in 2000, 2005 and 2009. The third edition of the book, like the previous two, is intended to convey to the reader the basic concepts and principles of medical statistics that are widely used by foreign doctors and biologists. The book contains the necessary theoretical part and in an accessible form gives a practical description of how the statistical methods in clinical trials may be used. The low level of use of statistics in the domestic medical science is one of the main reasons that has 111 years of the Nobel Prize in medicine are not awarded to Russians. The value of this book for medical science is defined and carried out in the Russian reform of Russian science, including reform of the VAC system and scientific evaluation. The manual is intended for students, graduate students and doctoral students of medical universities, biological faculties of universities, doctors, clinicians, researchers, and anyone who is in favor of evidence-based medicine..

Ashis Banerjee. Medical statistics made clear: an introduction to base concepts. Applied medicine publishing house, 2014. - 287 pages of the Lane from English V.P. Leonov.

The edition represents an introduction course by the principles of statistics. Basic concepts and the principles of statistical researches in relation to medicine are provided. Unlike the majority of similar editions, the specified subjects are stated briefly and well. Reading the book does not require knowledge of difficult sections of the higher mathematics, there is quite enough of what are given at school. Implementation in practice of the principles of evidential medicine dictates need of understanding of statistics. After acquaintance to the book the reader will be able critically to estimate the numerous publications containing statistical terminology and results of the described researches. The gained knowledge will help to avoid mistakes in planning of biomedical researches, and also in a statement of their results. As big advantage of the book serve the glossary and the detailed subject index.

"Some mockery". The deputy Kalashnikov about problems of medicine and unwillingness of the Ministry of Health to recognize them.... It is necessary to reveal risk groups and people with predisposition. It is not expensive at all. This approach is known since the time of Semashko and is successfully implemented in Cuba taking now on quality of health care the 18th place in the WHO classification. Russia - on the 133rd. It while in Cuba per person health care it is financed 10 times less.

Many measurements - many equations. Few measurements - even more equations.
We simplify and complicate predictors.
The purpose defines the means.

In the three years that have passed since the publication on our website first 7 articles on logistic regression, they were read by about 15 thousand people. During this period, readers have sent many emails with questions about the relationship of the statistical analysis method with simpler methods. In our next article about logistic regression we just also discuss these aspects. On examples of the results of analysis of data collected by researchers from Kazakhstan, and a researcher from Chita, it shows that the total volume of the results, both in the logistic regression, and on more simple techniques necessary for an understanding of the results, make thousands of pages.

Music... that's what it said about her great Johann Sebastian Bach: "the Aim of music is to touch hearts". In childhood the author of these lines received his musical education. Their favorite instruments were the mandolin and guitar. Favourite composers - Vivaldi, Bach, Albioni, Boccherini, Bellini, Corelli, Scarlatti. In the 80-ies of the last century in the Tomsk visited the concerts of Maestro Vladimir Spivakov. These concerts were organized by Yegor Ligachev, the former at that time first Secretary of the Tomsk regional party Committee. On their first concert in Tomsk Vladimir Spivakov came alone. Beautifully played the violin! The concert hall was filled with listeners who were thrilled with his concert. It was then that I was able for the first time to meet him and take his autographs on his records. In the future, attended all his concerts. In 1979 Vladimir Spivakov organized a chamber orchestra "virtuosos of Moscow". One day in the 90-ies Vladimir Spivakov had to come to Tomsk with the "Moscow Virtuosi", and within three days to give 3 concerts. However, due to problems with the fuel in those days, their plane landed in Omsk, where they stayed 2 days. And when he arrived in Tomsk, in one day we spent all 3 concerts that I have attended. And again took autographs on new records and made a lot of photos of Vladimir Spivakov.

Music... It always helps. That's why I send almost all my correspondents files with good music. Love music listen to it more often. And it will help you better understand biostatistic and the results of the statistical analysis...


February 13, 2014 Vladimir Spivakov and "virtuosos of Moscow" gave a concert in Krasnodar. I visited this wonderful concert, and met again with Vladimir Spivakov. Gave him his gramophone record, photographs, and a book.

Biometrics - 16 years! And that was before? Now what? Leonov V.P.
16 years ... Age considerable ... How did our website? And if it became popular?
Initially, our site has been divided into Doktor.Ru site, which was created in Khabarovsk. That looked like this section, for example, July 20, 2001. Since those years, speed of information transmission on the Internet was low, then in order to facilitate access to the biometrics we opened a "mirror" (copies) in cities such as Tomsk, Vladivostok, Moscow, Kiev. Later, when the site Doktor.Ru moved to Moscow, separate hosting biometrics in Tomsk was made. Over time, the need for a "mirror" site in other cities disappeared, and biometrics remained in Tomsk. Biometrics Readers in their letters often ask the question of what were the motives of this site? To talk a little bit about it, go back to 27 years ago, in the past.

Biometrics - 16 years! November 19, 2015 our site was 18 years since its inception. Over the past year there was a lot of communication with specialists in medicine and biology from different cities and countries. At their request, a series of articles on logistic regression was continued. It was also done a lot of work on the statistical analysis of the data collected by them ...

V.V. Nalimov. Tightrope Walker. Memories. "... Considering this subject, I proposed to introduce a new interdisciplinary specialization... In many foreign countries, this process started a long time ago. There have gained the right to exist such a profession as biometrics. But to realize this plan failed. Not supported ero rector, I. G. Petrovsky. Strongly opposed to him in the then Ministry of higher education. One of the senior employees of the Ministry angrily remarked: "what do we write in the diploma?" Strict regulation prevailed over everything and including on the structure of University education. "

V.V. Nalimov. In search of other meanings. "Our society lives soothingly - he's got shelter: the vast majority of it believes in the infallibility of science. Believes in its absolute objectivity. Believe as previously believed in the infallibility of religion and the omnipotence of magic. In our country every big decision is usually accompanied by a spell, sounding like this: "... the proposed solution scientifically". But whether science itself that ideal of science, which was formed around it? The science is becoming more scientific with the development of scientific and technical progress? "

The new structure of the Commission of the Russian Academy of Sciences on fight against a pseudo science is approved. The made decision the structure of the Commission increased from 46 to 59 people. And now from 19 new members of the commission 14 have a biological and medical profile. The made changes reflect those important processes which happen in the Russian science, and also transformation in threats from a pseudo science.... Now in the pseudoscientific market the medical charlatanism addressing, first of all, not the state, and directly citizens who pay for inefficient, and at times and dangerous "methods of treatment" dominates. The companies which advance these methods behave aggressively, apply effective PR technologies to forming in own favor of public opinion. As a result of such processing the people trusting to biomedical charlatans already made considerable electoral base that negatively influences adoption of the state decisions in the field of medicine and biotechnology.

P.S. The structure of the Commission included the famous specialists in evidential medicine MD V. V. Vlasov and k.b.n. N. N. Khromov-Borisov.

Superstate without energy. "... receipts in the budget of the Soviet Union from sale abroad fuel and energy goods and the electric power... during 1980-90 averaged 8-10 percent from all income of the country. At the same time... in pre-crisis 2013 the share of the oil and gas income in the budget of Russia made 50 percent. Since 2014 it begins to decrease: in the beginning to 48 percent, then, in 2015, to 47 percent. According to forecasts, in the following, 2016, it will make 43 percent.... the collapse of the oil market will mean a collapse for the economic, social and political system existing in modern Russia".

IF the DOLLAR GROWS, SO the RUBLE IN the COUNTRY DOES NOT WORK! Fault to all is the incorrect financial policy in the country: the investment credits the Russian banks give a minimum under 10-11% per annum, and the western banks - under 2-5% per annum.
