predict.tidyfit.models {tidyfit}

Predict using a tidyfit.models frame

Description

The function generates predictions for all models in a tidyfit.models frame and outputs a tidy frame.

Usage

## S3 method for class 'tidyfit.models'
predict(object, newdata, ..., .keep_grid_id = FALSE)

Arguments

object

model.frame created using regress, classify or m

newdata

New values at which predictions are to made

...

currently not used

.keep_grid_id

boolean. By default the grid ID column is dropped, if there is only one unique setting per model or group. .keep_grid_id = TRUE ensures that the column is never dropped.

Details

The function uses the 'model_object' column in a tidyfit.model frame to return predictions using the newdata argument for each model.

When the response variable is found in newdata, it is automatically included as a 'truth' column.

Value

A 'tibble'.
