proc panel

[sasphd]

I run proc panel. But I obtain this error message

ERROR: No residual in the model to analyze. Computations will not be performed.

proc panel data=Joint_fixed printfixed;
id rank_no rankdate;
model estimate=logage logTNA logMT EXP_RATIO TURN_RATIO logtnasq / fixone noint HCCME=0 cluster;
ods output ParameterEstimates=res;
run;

Can you explain for me what is the reason for this error

The most likely cause of the error is a failed auxiliary regression that is used to calculate HCCME standard errors.  If you can email me the data at Bobby.Gutierrez@sas.com, I'll be glad to take a closer look at the root cause.
