Is there a test that I can use for a logistic regression that is similar to the Vuong test for OLS?

    $\begingroup$ Not clear what you are asking. What are the (non-nested) models that you are trying to compare? $\endgroup$ Commented Mar 17, 2015 at 5:02

    $\begingroup$ Why don't you just use the Vuong test? It is not an OLS-specific test. $\endgroup$

Indeed, there is a variety of goodness-of-fit (GoF) tests that can be applied to logistic regression as an alternative to the Vuong test (Vuong, 1989). I think that the following tests can be considered as relative equivalents in the above-mentioned context:

For some theory on GoF testing for categorical models (in particular, logistic regression models), deviance and LRT, as well as additional examples in R, Stata and SAS, see this nice presentation.


It seems that there are some issues of significant importance, when considering logistic regression (LR) models. In particular, it appears to me that nested vs. saturated models, sample size, data grouping in cases with continuous predictors are specifically important in LR GoF testing context.
