已经解决！！！！！！！！！！！！！！！！！！！！！！！

你好！请教个问题，怎样用Hausman Test来检验“内生性”问题？：在一篇文章中看到如下“ As there might have been endogeneity between variable A and variable B, Hausman’s test was carried out via an instrumental variable technique, a single-equation F-test.”
这个检验能用SPSS完成吗？
非常感谢！

谢谢啦

res7<-mlogit(mode~0|ttme+gc,data=CLOGIT,reflevel="car",print.level = 0)
summary(res7)
res8<-mlogit(mode~0|ttme+gc,data=CLOGIT,reflevel="car",alt.subset=c("car","air","bus"),print.level = 0)
summary(res8)
hmftest(res7,res8)

怎么解决的呀！！！麻烦您回复一下
