作物营养施肥回归方程变量单位换算及其与回归系数的关系

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

  • 摘要: 本文介绍了回归方程中变量单位换算的三种方法:对于能找到原始数据的回归方程,可以采用数据变换法对于找不到原始数据的回归方程,可以采用回归系数换算法和变量代换法。回归系数换算法与变量单位换算系数和回归方程的种类有关。

     

    Abstract: 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.
