Undo slim_krls() (placeholder)

Heavy fields (K, V, Vsq, Vty, vcov.c, vcov.fitted) cannot be reconstructed without X and y and the original hyperparameters. This function therefore re-fits is not attempted; it simply returns the input unchanged and (optionally) prints a hint to refit. Reserved for a future release where re-construction from cached state may become available.

Usage

unslim_krls(fit)

Arguments

fit

A krls_rr fit previously passed through slim_krls().

Value

fit, unchanged. Refit krls() with the original call to rebuild the dropped fields.
