• Target Index/alternatives for Process Screening

  For some dumb reason I was thinking that Target Index normalized on the Spec window, and I'm realizing now that it normalizes on the within sigma, which is a problem as I have a lot of mathematically significant signals that aren't practically significant.  So, couple quick questions.    If you provide a specified sigma will the Target Index use that instead of within?  That will at least standard...

I am using Lasso as the estimation method. I opted to used generalized regression due to the large correlation among some factors.  I have a quick question related to this model: one of the main factors (seedAT) was removed f...
