Hello!

 

I ran a logistic regression model in SAS VDMML in SA Viya for Learners but i could not find any ouput related to the Odds Ratios (like it was in SAS EM). Is this output missing only form SAS Viya for Learners and exists in the professional version of SAS Viya? It will be included in future versions of SAS VDMML - Viya for Learners? Can we produce it easily through the pipeline with maybe a piece of code?

 

Thanks in advance,

 

Andreas

Hello,

 

As far as I remember, the odds ratios are indeed not part of the Results

returned by the Logistic Regression node in SAS VDMML.


For the odds ratios you can run the (winning | selected) model in a code node using :

  • PROC GENMOD (SAS/STAT)
  • PROC LOGISTIC (SAS/STAT)
  • PROC LOGSELECT (Visual Statistics)
  • PROC CATMOD (SAS/STAT)
  • PROC GLIMMIX (SAS/STAT)
  • PROC GENSELECT (and HPGENSELECT Procedure)

I think VDMML is using PROC CAS statements using the logistic action in the regression action set to fit a logistic model to your data.

proc cas;
   regression.logistic

Good luck,

Koen

Hi!

Thanks for your answer!

Let us say that i have a pipeline with the following nodes: Data--> Imputation--> logistic regression-->SAS code
What sas code should i write to the SAS code node so as to get the odds ratios from the model fevelopped in the logistic regression node?

Thanks in advance,

Andreas
