model
A ml_model fit.
Details
These functions are currently experimental and not yet ready for production
use. Unfortunately, the training summary information for regression fits
(linear, logistic, generalized) are currently not serialized as part of the
model fit, and so model fits recovered through ml_load will not work
with e.g. fitted, residuals, and so on. Such fits should still
be suitable for generating predictions with new data, however.
