Interaction effects in regression

cramsden

Is there anyway to quickly look for interaction effects among predictor variables when doing any sort of linear regression modelling in JASP?

EJ

Yes. Under the "model" tab, select the variables for which you'd like to see an interaction in "Components", and drag them at the same time to the "Model Terms" box. Dragging them at the same time will add the interaction to the model.

Cheers,

Thank you! I didnt know this existed

Is it possible to do this in the regularized linear regression so I can use lasso on it? I dont see the model tab there

EJ

Let me look into that...

Any update on this?

Hi, sorry for the late reply.

Regularized linear regression does not allow for interaction effects at the moment. If you open a feature request at our GitHub page we'll assign it to the appropriate developer.

Cheers,
