Dear mark: You would not generate a variable (althought you could if you really wanted to). After any estimation command a number of statistics are temporarily stored. You can see which by looking in the manual or type -ereturn list-. In the example below you can see that the log likelihood is stored in e(ll). You can use that in your calculations. See -help return- and the manual entry for return for more information. Example: . sysuse auto (1978 Automobile Data) . quietly logit foreign weight mpg . ereturn list scalars: e(N) = 74 e(ll_0) = -45.0332095569914 e(ll) = -27.17515619914122 e(df_m) = 2 e(chi2) = 35.71610671570034 e(r2_p) = .3965529779806182 macros: e(depvar) : "foreign" e(cmd) : "logit" e(crittype) : "log likelihood" e(predict) : "logit_p" e(chi2type) : "LR" matrices: e(b) : 1 x 3 e(V) : 3 x 3 functions: e(sample) . di e(ll) -27.175156 Maarten -----Original Message----- From: Marc F.

I would need such a variable to compute the test statistic for a Vuong (1989) test. Cheers, Marc __________ Marc F.
