Why am I getting no K-fold validation for my linear regression? It only shows "."

Doing a linear regression, and both in stepwise and in the final model output it only shows "." under K-fold cross-validation?

 

Why? I recall seeing a K-fold # for my previous model, though I don't remember the exact section or screen.

Hi @chriscic42 ,

 

  Without some more specifics about what you're doing (e.g. steps and or data table -- can be anonymized), it's hard to figure out the issue you're coming across.

 

  However, when I try on one of my data table to run the Stepwise Fit personality under the Fit Model platform and select K-fold Crossvalidation from the red hot button, it runs just fine using the Max K-fold RSquare for the Stopping Rule. Also, are you using a crossvalidation column?

 

  If you can provide screenshots of the steps you're doing or the data table with the script that reproduces the issue, it would help a lot to figure out what's going on in your situation.

 

Thanks!,

DS
