"Modern Problems of Applied Mathematics and Mechanics: Theory, Experiment and Applications", devoted to the 90th anniversary of professor Nikolai N. Yanenko

## Shchelkanov N.N.## New mathematical model of linear regression between two physical parameters in view of their random errorsA generalized equation is presented for determination of the regression coefficients of the linear equation Y = K0 + K1 X in the general case, when the point spread in the correlation between X and Y is caused both by random measurement errors and by uncontrollable physical factors. All the known equations for the regression coefficients appeared to be particular cases of the equation obtained. Conditions of use of known expressions are determined.
