Dear Statalisters,

I am having trouble with running the commando nlogitrum. I run the
following syntax;

global a1 "male doc_age doc_age2 child0_18 doc_child married spouse_doc
male_child male_age aut_year reform"

global b5 " gp psychiatry surgery2 surgery3 gen_med2 gen_med3 oto_rhino
ophtalmology lab_med other paedriatrics obgyn anae"

global a1b5 "$a1 $b5"

nlogitgen type=moon_group(hospital:1|2, non_hosptial:3|4)
nlogittree moon_group type

nlogitrum chosen $a1b5, group(idnr) nests (moon_group type)
nlogitrum chosen $a1b5, group(idnr) nests (moon_group type) ivc(hospital=1

I get the message "no independent variables". Does enyone know what I
shold to to modyfy the Syntax?

Regards Ragnhild
