虚拟变量是将类别变量赋值,加入model,使用regression。
RESULTS: Forward stepwise multiple regression analyses revealed that body weight, navicular drop, and standing foot angle predicted mean peak heel forces during forward and backward walking. CONCLUSIONS: Heel forces during forward and backward walking increase as body weight and navicular drop magnitude ...

多重相关系数(multiple correlation coefficient) 又称复相关系数是因变量与所有自变量之间的关系。而相关关系是两两之间的关系。 因为:T(n)=(f(1,n))^1/2所以 多重共线性可能会误导结果,有可能变弱甚至变负。 下面情况暗示存在多重共线性,Model显著但是单独的回归系数却不显著。

A stepwise multiple regression analysis using backward elimination was utilised to examine the relationship between the postural measures and the muscle performance ratio measures. Separate models were used for the two different postural conditions (standing, sustained sitting). Gender was included as a ...
