Re: st: Cramer Ridder test for multinomial logit model - syntax error

[Tirthankar Chakravarty <tirthankar.chakravarty@gmail.com>]

Sangamitra,

You need to tell the list where you get user-written ado-files from. In my case:
. ssc install crtest
. which crtest
<output omitted>
*! version 1.2 (25 November 2003)               Joao Pedro Wagner de Azevedo

This routine will not work with a fully updated Stata 10.1 because the
scalars returned by -mlogit- have been renamed since Stata 8 (my
guess), viz., the number of categories used to be returned in
"e(k_cat)", but is now returned in "e(k_out)". So you need to change
all instances of the occurrence of "e(k_cat)" in the file "crtest.ado"
to "e(k_out)" (on line #s 28, 43, 44 and 81). Then, as in the
following example, -crtest- should work fine:

*********************************************
webuse sysdsn3, clear
mlogit insure age male nonwhite site2 site3
crtest

To every ω-consistent recursive class κ of formulae there correspond
recursive class signs r, such that neither v Gen r nor Neg(v Gen r)
belongs to Flg(κ) (where v is the free variable of r).
