Subject | st: -svy:cloglog- and margins |
Date | Tue, 13 Aug 2013 15:51:38 +0000 |
Hello, I am using the -svy:cloglog- command. Although the following code has run successfully, I find the following issues: 1) There are no results on AIC or log likelihood. 2) The covariate (category) labels do not get printed. 3) STATA has encountered memory problems with the _margins- command. Code and part of the log file are appended below. I would appreciate receiving your help resolve the issue. Thanks, Pradip ****************** CODE BEGINS HERE ************************************ svyset psu [pweight=wt8], strata (stratum) vce(linearized) singleunit(missing) capture noisily svy,subpop(xa_age2534): cloglog dead i.sex ib2.xspd2 ib3.xsmoke /// i.racehisp i.educ_cat ib2.bmicat i.xchronic i.dur_cat, eform nolog est store xa_age2534 // predicted probabilities margins, at(xspd2=1 sex=1 xsmoke=1) ********************* CODE ENDS **************** **** part of log is shown below ******** . set mem 1100m Current memory allocation current memory usage settable value description (1M = 1024k) -------------------------------------------------------------------- set maxvar 5000 max. variables allowed 1.909M set memory 1100M max. data space 1,100.000M set matsize 400 max.

You have the following alternatives: 1. Store existing variables more efficiently; see help compress. 2. Drop some variables or observations; see help drop. (Think of Stata's data area as the area of a rectangle; Stata can trade off width and length.) 3. Increase the amount of memory allocated to the data area using the set memory command; see help memory. Pradip K.
