Hi everyone,
I had used the interactive binning node to bin my interval input variables into 4 quantiles:
However, when I connect it to the regression node, only 3 quantiles show up:
Would there be a reason why only quantiles 1, 2 and 3 show up in the parameter list?
Thank you!
Yes absorbing the last level with the intercept is the default option in REG node. If you fitting a Logistic regression you cold suppress the intercept and change input coding to GLM then you see all four coefficients for your binned variable.
when performing optimal binning you are transforming interval variable to nominal variable with 4 levels. The last level by default is treated as the reference group and the first three levels are compared with the reference levels.
