Dear Hendrik,

the problem is that your var dep in the main equation does not have
missing values.
Like I don´t have better data, I will use this below with
transformations, oks. The important is that it works, not if make
sense!

***********begin example********
webuse sysdsn3, clear
preserve
rename age income
replace income = . if insure != 1
selmlog income nonwhite, select(insure=male nonwhite) showmlogit lee
selmlog income nonwhite, select(insure=male nonwhite) boot(50) lee
restore
*********end example****************

HTH,

Joao Lima
