Nested Test after Count Regression

[gmerce]

Hi,

Can I use the Nested Test Tool after a Count Regression Model (Poison) and a Stepwise ? Is it compatible ?

Here are my WF and errors :

 

Thanks,

Hi @gmerce

It seems that the error you are seeing is very likely to be a result of using the same models to be examined on the nested test and as a result it errors out.  On your screenshot it also shows that both models have the same file size indicating this is the case.  I have managed to replicate the issue comparing two identical models:

If the input models have been configured correctly the nested test model should work.   

Hope that helps.

Hi,

That's correct it doesn't work when the moodels in input are exactly the same. It looks like my stepwise wasn't working.

It's working fine with this example : 

Thanks a lot for your help.
