A simple method for correction of the systematic error in calculating biological age by the multiple regression equation

There was proposed аsimple method of the correction of systematic error of the equation of multiple regression while calculating biological age. The principle of this method is in the vertical transfer of points on the graph "predicted age -chronologicalage" on a diagonalline. At the same time, the distances from the points to the regression line are maintained. This correction eliminates the systematic error of the multiple regression equation and increases the accuracyof the biological age model.
