知道怎么算了。还要算出两个预测变量和因变量的相关系数才能算各自的效应量。

[mpluser] R-square问题求解
大家好,我在运行logistic回归时遇到点疑惑向大家求教(见下文模型结果)。
因变量为分类变量(CATESH=0,1,2,3),自变量为两个连续变量(BIS, ER)。最后结果显示R-SQUARE为0.216,标准化的路径系数分别为0.325和0.193。
请问:1、结果中总的R-SQUARE(0.216)是怎么算出来的?(如果只放入一个变量BIS,最后结果标准化路径系数的平方刚好等于R-SQUARE,但当放入两个变量,显然R-SQUARE不等于两个路径系数的平方和)
2、能不能像SPSS的回归分析那样得出两个预测变量各自的R-SQUARE?或者怎样算出来?
初次接触Mplus,有很多不明白的地方,向大家求教。
