Dear Herv�,
Multinomial logit and gologit estimate multiple parameters for each
explanatory variable. What -mlogtest, lr- does is a likelihood ratio
test of whether all parameters of a single explanatory variable are
simultaneously equal to zero. In other words: it compares the
likelihood of a model with and without the explanatory variable
(leaving a variable out is the same as constraining all the parameters
for this variable to be zero).
This can easily be implemented in STATA. In the example below I test
whether all parameters of weight are equal to zero. It results in a
chi-square statistic of 18.27 with 4 degrees of freedom, so the null
hypothesis (all parameters of weight are zero) is rejected at the .001
level.
