Suppose one estimates the coefficient β2 in E[Y] = β0 + β1X 1 β2X 2 by stagewise regression. That is, first the model E[Y] ≅β0 + β1X 1 is fit using simple linear regression followed by a simple linear ...

We revisit an article by D. A. Freedman on screening variables for regression models. After summarizing his asymptotic results we show that the theory does not entirely explain the results of computer ...
