What is the appropriate way to test the equality between coefficients of the same variable between two models that are identical except that, in the latter case, the data are weighted, and in the former case, the data are unweighted?
The weights are used in order to match treatment and control groups on propensity scores. I would like to see if the magnitude of a coefficient changes or remains the same.
Thank you,
Jacob Felson
