Hello fellow data scientist,
I currently reading the paper by Stekhoven & Brühlmann about MissForest. I was wondering how to deal with variables that are restricted by domain knowlege. I.e. no women can not have had prostate cancer in the past, so missing values are wanted for this item. Should I just exclude such variables (were missing values are wanted / inteded) from the MissForest imputation?
If so how can I combine these variables with the imputed datasets afterwards?
I hope this is specific enough. Thanks in advance
