GMM = generalized method of moments, correct?&nbsp; That is a method for fitting dynamic panel models.&nbsp; FMM = finite mixture method.&nbsp; That is a method for fitting multi-modal type data, where the response is a single value, but is generated by different processes.&nbsp; Not really dynamic, and definitely not suited for panel type data.</P> <P>&nbsp;</P> <P>As you state, GMM is supported by PROC PANEL and PROC MODEL, but it is not supported by PROC FMM.&nbsp; So far as I can determine, GMM is exclusive to SAS/ETS.</P> <P>&nbsp;</P> <P>SteveDenham</P> Fri, 05 Feb 2021 12:31:03 GMT https://communities.sas.com/t5/Statistical-Procedures/GMM-Estimation/m-p/717054#M34681 SteveDenham 2021-02-05T12:31:03Z
