Internals Safely Make Predictions on a Fitted Workflow from Model Spec tibble

Description

Safely Make predictions on a fitted workflow from a model spec tibble.

Usage

internal_make_wflw_predictions(.model_tbl, .splits_obj)

Arguments

.model_tbl

The model table that is generated from a function like fast_regression_parsnip_spec_tbl(), must have a class of "tidyaml_mod_spec_tbl". This is meant to be used after the function internal_make_fitted_wflw() has been run and the tibble has been saved.

.splits_obj

The splits object from the auto_ml function. It is internal to the auto_ml_ function.

Details

Create predictions on a fitted parnsip model from a workflow object.

Value

A list object tibble of the outcome variable and it's values along with the testing and training predictions in a single tibble.
