In the real work statistical data processing of the electrocardiograms taken from works of Antonov is made. As it is known heart in the course of functioning generates electricity. Measurement on a surface of a body of biopotentials of heart of the person call assignments. The electrocardiogram represents dependence of instant values of a potential difference between certain points on a body of the person. Histograms of pressure and duration of an interval of RR are constructed. The mathematical modeling connected with statistical laws, allows to reveal the main regularities of these medical researches, both at the healthy person, and at the patient. Results can be used in medical practice.

Keywords: duration of an interval of RR, histogram, Gauss function, vibrating arrhythmia, sinusovy tachycardia, ventricular ekstrasistoliya, hypertensive illness.

USE OF METHODS OF THE SMALLEST SQUARES AND ELEMENTS OF

THE CORRELATION ANALYSIS IN MEDICOBIOLOGICAL

RESEARCHES

G.N. Litvintsev Heads M.A. Kutimskaya, M.U. Buzunov Irkutsk State Academy of Agriculture, Irkutsk, Russia One of the main methods in biophysics is modeling. In this work methods of matematichky processing of results of medico biological measurements are considered. Methods to mathematical statistics allow to systematize and estimate experimental data considered as casual. Statistical characteristics of medicobiological information are resulted in certain dependences which allow to apply methods of mathematical statistics to the research purposes.

Key words: the approximating line, coefficient of correlation of r, linear correlation, determination coefficient, the regression equation.
