Beginning in SAS 9.2, the ModelFit table titled "Criteria For Assessing Goodness Of Fit" and the ParameterEstimates table titled "Analysis Of Initial Parameter Estimates" are not created by default when the REPEATED statement is specified. As a result, ODS statements referring to these tables will produce warnings that the tables were not created. Specifying the REPEATED statement causes a GEE model to be produced. Prior to SAS 9.2, the ModelFit and ParameterEstimates tables were produced even when a GEE model was fit. The ModelFit table contains the log likelihood and other statistics. The statistics in this table do not apply to GEE models since GEE is not a likelihood-based estimation method. In SAS 9.2, the ParameterEstimates table can be produced by specifying the PRINTMLE option in the REPEATED statement. Note that the parameters in this table are only used as initial values to begin the GEE estimation algorithm which produces the parameter estimates of the final model. The final model parameter estimates appear in the GEEEmpPEst or (if the MODELSE option is specified) GEEModPEst table titled "Analysis Of GEE Parameter Estimates". To obtain correct table names for the tables produced by various statements and options in PROC GENMOD, see "ODS Table Names" in the Details section of the GENMOD documentation.
