Re: st: Re: Fischer's exact when the expected counts are known

[Steven Samuels <sjhsamuels@earthlink.net>]

Richard has multinomial data: four categories with expected counts.  
There is no such thing as a Fisher Exact Test for multinomial data;  
Fisher's test is for two-way tables, and tests the hypothesis of  
independence. Richard wants to test the fit of the observed data to  
the expected.  He needs Ben Jann's -mgof- (from SSC) or the packages  
listed at the bottom of its help page.  -mgof- uses simulation to  
approximate the exact distributions of  the Pearson Chi Square and  
likelihood-ratio goodness-of-fit tests.
