t-Value from proc genmod

Hello,

When I am using "proc genmod" to build models, I am trying to output t-Values for the parameters. I have tried various output statements including ods output, especially, "ods output ParameterEstimates = xxxxx;". But I can't get t-Values anywhere. Can someone please enlighten me? Thank you.

The tests for the parameter estimates are based upon a Wald Chi-Square test and not a t-test. The ParameterEstimates table should have those values and the corresponding p-values.

Thank you, Rob. I am not familiar with Wald test, even though I did see that the parameterestimates table provides LowerWaldCL and UpperWaldCL. Both are so close to the estimates (which means the estimates are good) . I always think that t-Values should not be so close to the estimates.

Thanks, again.
