Hi Folks:

 

I'm trying to run proc countreg on spatially correlated data. But I get error: WARNING: The WMAT= option and/or SPATIALID statement will be ignored because the spatial lag model is not valid.

Where should I look at to start with to investigate the problem? Any known issues associated with this Warning? 

 

proc sort data=mydata; 
by ID1NAME IDNAME; 
run;
ods trace on; 
ods output  ParameterEstimates=par; 
proc countreg data=mydata Wmat=Wmatrix;
model n_covid =db_ocular_rate p55_64 p65_74 p75_84 p85/offset=ln dist=negbin;
ods trace off; 
run;
