Many thanks to Richard and Scott! Problem solved.

Something to be aware of with Scott's solution: most of the ereturned stuff gets zapped once you run foo2. In particular, since e(predict) gets zapped, the p option on predict doesn't work. You can probably add lines to Scott's program to revive the ereturned stuff that gets lost but maybe there is a better way. The following shows what I am talking about: . sysuse auto (1978 Automobile Data) . qui logit foreign mpg weight . ereturn list scalars: ...Bunch of stuff... macros: e(title) : "Logistic regression" e(depvar) : "foreign" e(cmd) : "logit" e(crittype) : "log likelihood" e(predict) : "logit_p" e(properties) : "b V" e(estat_cmd) : "logit_estat" e(chi2type) : "LR" matrices: e(b) : 1 x 3 e(V) : 3 x 3 functions: e(sample) . predict prob1, p . foo2 . ereturn list macros: e(properties) : "b" matrices: e(b) : 1 x 3 . predict prob2, p option p not allowed r(198); ------------------------------------------- Richard Williams, Notre Dame Dept of Sociology OFFICE: (574)631-6668, (574)631-6463 FAX: (574)288-4373 HOME: (574)289-5227 EMAIL: [email protected] WWW (personal): http://www.nd.edu/~rwilliam WWW (department): http://www.nd.edu/~soc * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
