Normally, your outcome and main exposure variable are already complete but since I have a longitudinal design, not all the outcome variables are completed.&nbsp;</P><P>should I add the main outcome variable to the imputation model or leave it out?</P><P>thank you</P><P>&nbsp;</P> Sat, 09 May 2020 13:50:49 GMT katy-barry 2020-05-09T13:50:49Z https://communities.sas.com/t5/SAS-Programming/multiple-imputation-with-missing-outcome-data-longitudinal-study/m-p/646385#M193342 <P>Hello,&nbsp;</P><P>&nbsp; I am working with a dataset in which we measure if a person was unemployed in different years. for example, we ask "are you currently unemployed" in 2009, 2011, 2014, etc. I am wanting to do multiple imputation on my dataset but I do not know if I should add the outcome into my model because for some waves of data, people did not answer the question and if I include it into the multiple imputation model, SAS will generate values for my outcome variable which i do not want ( I know with multiple imputation, you just want the covariates to be filled in but not the outcome variable).
