Hi everyone!
I've run the following syntaxes to compute the global test of the parallel lines assumption as pre-steps of running gologit2. The issue is that the estimation result constrained not found. Could you please assist me to figure out what should I do!
**1)Constrained

. asdoc gologit2 beautiful_freq beautiful_locale_score beautiful_scope_score beautiful_upkeep_score beautiful_accord_score beautiful_perceived_age_score beautiful_shape_score cntr_value_score cntr_acumen_score cntr_response_score i.tourist i.gender i.edu age if beautiful_freq != 0, pl lrforce store(constrained) replace save(serie1_1_gologit2_beautiful_constrained) title(Model I: The Beautiful (Constrained))

**2)Unconstrained

. asdoc gologit2 beautiful_freq beautiful_locale_score beautiful_scope_score beautiful_upkeep_score beautiful_accord_score beautiful_perceived_age_score beautiful_shape_score cntr_value_score cntr_acumen_score cntr_response_score i.tourist i.gender i.edu age if beautiful_freq != 0, npl lrforce store(unconstrained) replace save(serie1_2_gologit2_beautiful_unconstrained_WAR NING_NEGATIVE_predicted_probability) title(Model I: The Beautiful (Unconstrained))

**3)global test of the parallel lines assumption
.asdoc lrtest constrained unconstrained, replace save(serie1_3_lrtest_beautiful) title(Model I: The Beautiful (global test of the parallel lines assumption)

estimation result constrained not found
