Dear All:

1 - I would like to evaluate the goodness of fit of a gologit model (in general and versus an ologit). With fitstat, I get several statistics. Which statistics would you suggest to take and how would you use (= read) it?

2 - Following my first question, I read in a working paper that the author used the Akaike Information Criterion (AIC) to compare the goodness of fit of two models: gologit and ologit. But I still don't understand how to use the AIC. Is there a threshold? Should I simply compare the two AIC got with fitstat? If so, what is the "best" model? With the highest or lowest level? (Sorry, but my level in statistics is not good enough to find the answer from the computation of the AIC).

Additionally, would you have a good reference which explains how to evaluate the goodness of fit of gologit and ologit models?

Best regards
