STATA

Øv, bøvler med at få lavet en logistisk regressions analyse i STATA! Har én variabel (negativ nummerisk,ex -4,489135) og binært outcome; case/kontrol (1/0), men STATA fejlmelder hele tiden! Er der ikke nogle af Jer kloge hoveder der kan se hvad jeg gør forkert?
Har brugt følgende kommandoer uden held:

. logit case hb_score, or

(mopt__pl_init() in lmataopt, compiled by Stata 11.2, is too new to be run by this version of Stata and so was ignored)
                <istmt>:  3499  mopt__pl_init() not found
r(3499);


. xi: logit case hb_score, or

(mopt__pl_init() in lmataopt, compiled by Stata 11.2, is too new to be run by this version of Stata and so was ignored)
                <istmt>:  3499  mopt__pl_init() not found
r(3499);

. xi: logit i.case hb_score, or
i.case            _Icase_0-1          (naturally coded; _Icase_0 omitted)
