> HI,
>     In logistic regression model practice,Test of regression coefficient and whole
model fitting are very important.Can you add some effective support on these Aspects?
>     Such as,The likelihood ratio test or the wald test is offer used for test of coefficient,and
the Hosmer-Lemeshow test is used for evaluate the model fitting.
>     Learning that we have ROC and Precision-Recall already,but can you also provide KS
statistic,which is mostly used in Model evaluation aspect?
