STUDY ON VARLATES UNIT TRANSFORMATION IN REGRESSION EQUATION AND THE EFFECTS OF UNIT TRANSFORMATION ON REGRESSION COEFICIENTS

Three methods are recommended to transform variates unit in regression equation.Using the transformation method of data in the situation which the original data is at hand, and using the Transformation method of variate and Transformation method of regression coeficient in the situation which the original data is not at hand. To the Transformation method of regression coeficient , should be considered both the transfomation ratio of the units in a variate and the type of regression equation. Also.a sample are given in the paper.
