PROC GENMOD Estimate Statement Warning

[salexgray]

Hello everyone!

I'm relatively new to SAS and am currently running a Poisson regression with robust variance estimation. Within this code, I'm using the ESTIMATE statement to calculate the relative risks for each level of my IND2 variable (values from 0 to 5), and I am coming across this warning. Does anyone know how I can fix this? 

Also, what is the easiest way to graph these relative risks on one plot with the confidence intervals included? 

Thanks!

Is this the log that goes with the code you show? The log talks about a variable INDEX2, which does not appear in the code you show.

When asking about warnings, errors or specific notes please copy from the LOG the entire procedure or data step code will all the warnings, notes and any errors. All the elements. Then paste into a code box opened on the forum with the </> icon.

The main message windows on the forum will reformat text and can make some diagnostics not appear correctly with the log entry.

The entire code clarifies any question about possible misspelled items when showing some of the code.

I think your parameterize is param=ref . But your 'estimate' is param=glm .
either change param=glm , or use 'ref' to 'estimate' .
