摘要
本文经过分析,提出实用性相关系数的基本临界值,r_0=3^(-0.25)。并且结合参数特点和回归路径,探讨了回归方程在岩土参数预测中的实用性相关系数界限值。
The basic (?)ritical value of correlation-coefficient, r_(?), of practieability is presented through analysis in this paper, r_0=3^(-0.25). Boundary correlation-coefficients of pra(?)ti(?)ability of regression equation in predi(?)ting parameters of rock and soil are also discussed by combining with the features of parameters and the regression path.
