In what sense is your model too big?

-avplots- can help (also -favplots- from SSC) with up to say 20
predictors, but with say 200 the graphs are not likely to be readable.
But -ladder- is at best partly relevant: the transform that most
nearly symmetrises a marginal distribution is not necessarily one that
is appropriate for transforming a predictor.
