  • Variable selection using stepwise backward selection following multiple imputation

    Dear all,

    I have used the search function on statalist, but have unfortunately not been able to find an answer. I am imputing two continuous variables in my model that I want to use for variable selection using stepwise backward. My goal is to retain a number of variables that are selected throughout my 5 imputation sets using stepwise backward selection.

    Unfortunately, the standard mi estimate command does not allow me to perform stepwise backward selection across imputation sets. I am hoping to get some suggestion as to how to go about this. Thank you very much.

    Sincerely,

    Jasper

    Jasper:
    I suspect that the best advice you can get from this list is: please, stay away from any stepwise procedure (see also http://andrewgelman.com/2014/06/02/h...se-regression/)!
    Kind regards,
    Carlo

      mim allows you to use stepwise. You can get mim from Patrick Royston's homepage:
      Code:
      net from http://www.homepages.ucl.ac.uk/~ucakjpr/stata
      net install mim
