Interaction terms in regressions

davidb

Hi all, new Alteryx user here. I am setting up a workflow around some predictive models I have - both a linear and logistic model. Normally (in R) I have interaction terms in these models, but I cannot see a way of implementing these conveniently, short of creating the variables separately. 

i.e. the logistic regression tool can happily make me:

lm(y ~ x1 + x2)

but not 

lm(y ~ x1 * x2)

Am I missing something or is there a good work around? I suppose I could make the interactions as separate fields but this will be very cumbersome for some of my larger models with hundreds of regressors.

Relatedly, is there a more convenient way logging regressors than simply making new fields?

Thanks

Hello,

Unfortunately, you would need to create these extra fields or run the model in the R tool.  If desired, the macros can be opened and adapted by right clicking on the tool on the canvas and selecting 'open macro' then saving as a copy.
