Abstract: byvar repeats stata_cmd for each distinct combination of values in varlist; varlist may contain string variables. Option e(elist) saves the E-class estimates e() named in elist which arise from stata_cmd. r(rlist) saves the R-class results r() named in rlist which arise from stata_cmd. b(coeflist) stores the regression coefficients for variables named in coeflist. se(selist) stores the standard errors of regression coefficients for variablesnamed in selist. generate creates new variable(s) corresponding to the quantities named in the e(), r(), b() and se() options. This is an update of byvar, described in ip9 of STB-27, for Stata version 8 and later.
