Selecting a subset of predictors after stepdown/from ANOVA for a clinical prediction model

Thanks so much, Dr. Harrell.

As I’m not a statistician, some of the methodologies are new to me. I might have misunderstood question/answer #18 in the following link (“Are automated variable selection methods justified if the only goal is to identify the strongest predictors? No”), and thought we could subselect some of the strongest predictors from the ANOVA/fastbw() for our clinical decision rule.

Thanks!
