One is able to do a Hosmer-Lemeshow goodness-of-fit test -lfit- after an ordinary logistic regression -logit-.

With -xtlogit y x,re-

-lfit- says 'last estimates not found'
Is it possible to do a H-L test after -xtlogit- please?

If so, which predict should one use

a) -predict predfit1 ,xb- (fitted values, the default)

b) -predict predprob ,pu0- (predicted probability Pr(y=1 assuming u_i=0)

A similar situation occurs with -lroc-

Kind regards, Garry
