Hi, I am getting an error when attempted to svyset data and run a logistic regression after multiple imputation. I ran 20 multiple imputations. Then, I svyset the data as a whole. Then, when trying to run a logistic regression with the prefix "mi svyset," the error arises "invalid psu variable name r(111);". Output is below. I am confused because I was not aware I need to enter the psu when running the logistic regression command; I was under the impression I only needed to enter "mi svyset" as a prefix. I tried entering the psu as part of the prefix, but that also gave me the same error message.
Thank you in advance!
