Hi everyone,
I am trying to run a missing data multiple imputation procedure. However, I get the following message:
"mi impute mlogit B5 = DV1_Successor_Party A5 B4 A3 Gender Age_Groups EmployedDummy Household_Income Residence Region Language N_Scale, add(10) rseed(1234)
mi impute mlogit: perfect predictor(s) detected Variables that perfectly predict an outcome were detected when mlogit executed on the observed data. First, specify mi impute's option noisily to identify the problem covariates. Then either remove perfect predictors from the model or specify mi impute mlogit's option augment to perform augmented regression; see The issue of perfect prediction during imputation of categorical data in [MI] mi impute for details. r(498);"
So, I want to choose the first route and specify noisily in order to identify the problematic covariates. Next, I insert noisily in the syntax command, but it is not working. I have inserted noisily in all the possible places in the syntax command, but it is returning variations of the message as above. What is the correct way to formulate the syntax in this case?
Thank you,
Ion
