Abstract: Algorithm of determination of coordinates of point of intersection of regression straight lines was elaborated. Regression straight lines characterize linear segments of measured dependence. Regression straight lines equations are given by simple application of the least-squares method to set of points, which with respect to given regression straight line are not outlying. Decision, whether the measured point of functional dependence is remote from the linear segment, is done in an objective way on the basis of special statistical criterion, which is a part of OK-LIN program, that allows processing of experimental data.
