Subgroup vignette: regularization, pre-specification, and visuals #79

Closed wlandau closed 7 months ago

wlandau commented 8 months ago

This PR improves the subgroup analysis vignette:

  1. Clarify that the vignette is not about subgroup selection. We assume the choice of subgroup variable is pre-specified and has enough justification already.
  2. Discuss regularization as a way to express skepticism about a subgroup-treatment interaction.
  3. Show how the new plotting options can view subgroup levels side by side.

@andrew-bean and @chstock, would you please review?
