Criteria for assessing ML model fit
-----------------------------------

	^mlfit^ 


Description
-----------

^mlfit^ estimates Akaike's Information Criterion -AIC- (Akaike 1974) and
Schwarz's Criterion -SC- (Schwarz 1978) for assessing maximum likelihood 
estimates model goodness of fit. 

This command can only be run after @glm@, @logit@, @clogit@, @mlogit@, @logistic@
or @poisson@ commands.


Examples
--------

	. ^glm case age sex rf, family(binomial) link(logit)^
	. ^mlfit^

	. ^logit case age sex rf^
	. ^mlfit^

	. ^logistic case age sex rf^
	. ^mlfit^
