Error in non-proportional odds model
Posted: Mon Sep 28, 2015 11:11 am
Dear members,
I am trying to fit two two-level ordinal logistic models, a proportional odds model and a non-proportional odds model, but have encountered an error message while running my syntax for non-proportional odds model. The error states 'error: design vector at level 2 is the wrong length (moni)'. As I'm fairly new to runmlwin and Stata, I wasn't able to figure out what is wrong with my code and how to fix it.
proportional odds model
Is anyone familiair with this message and able to explain to me what it means or provide some insides on how to fix this problem?
Thank you,
Dan

proportional odds model
Code: Select all
gen cons=1
drop if missing(hh_id, person_id, cons, k2a, i4a, fl1b, fl2a, fl3b, k1a, wb, city_age, dist_train, dist_airport)
recast float fl3b city_age, dist_train, dist_airport, force
***** Proportional Odds
sort hh_id person_id
capture noisily xi: runmlwin k2a cons (i.i4a fl1b i.fl2a fl3b i.k1a i.wb city_age dist_train dist_airport, contrast(1/3)), ///
level2(hh_id: (cons, contrast(1/3))) ///
level1(person_id:) ///
discrete(dist(multinomial) link(ologit) denom(cons) basecategory(4)) ///
nopause tolerance(10) maxiterations(250)
***** Non-Proportional Odds
sort hh_id person_id
