How to get standard deviations on multiply imputed AND weighted data

ejay0503 — Wed, 15 Nov 2017 15:26:35 GMT

Hello, all

Perhaps this is an easy question (but I can't figure out somehow!). I am using national data that is weighted so I multiple imputed the data using the weight. I am having trouble getting "pulled" standard deviations of the variables...I would greatly appreciate your help! Please see my code below.

(proc mi.....truncated)

proc surveymeans NOBS MEAN STDERR STDdata=perm.enjoy19m2 ;
strata RAESTRAT; cluster RAEHSAMP; weight R11WTRESP;
var age ;

domain _imputation_ ;
ods output domain = out ; run;

proc mianalyze data = out ; modeleffects mean;
stderr stderr ; run ;

Best regards,

In order to get a combined estimate you would need a measure of variation for the standard deviation. You might be able to calculate one using the Delta method or something similar but this is not something that SAS reports.

It's very good to know that SAS doesn't report SDs on imputed data. Thank you very much for your help, Rob!
