Subject | st: Re: dropping variables with lots of missing |
Date | Thu, 07 Jul 2011 10:38:56 -0400 |
Hi, I've been following the threads of dropping variables with missing values--I know and have used Nick Cox's dropmiss for a long time. But I also want to drop variables with lots of missing values. I could not figure out how to save any results from his nmissing, but I tried this in a do-file with misstable: foreach var of varlist trustbanks-angergovtintervene { misstable sum `var' keep if r(K_uniq) >= 4 } and it winds up deleting all cases for all variables (only three variables have less than 4 observations). What am I doing wrong? Many thanks, Ric * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
