In both PROC TSCSREG and PROC PANEL if you have any cross sections with all missing values then the following error message will appear in the SAS Log:
To circumvent the floating point zero divide error delete those cross sections with all missing values.
In PROC PANEL if you have any cross sections with only 2 observations and you see the following:
Then the following error message will appear in the SAS Log:
Under these conditions there is only a single observation available to estimate the model for those cross sections with 2 observations. Rather than fail with this error, the procedure should produce a note which indicates that the first cross section has insufficient data.
To circumvent the problem, either use PROC TSCSREG rather than PROC PANEL to fit the one-way fixed effects model with the lagged dependent regressor or remove all cross-sections with only 2 observations and rerun the analysis in PROC PANEL.
