.fit.gets {tidyfit}

General-to-specific regression for tidyfit

Description

Fits a general-to-specific (GETS) regression on a 'tidyFit' R6 class. The function can be used with regress.

Usage

## S3 method for class 'gets'
.fit(self, data = NULL)

Arguments

self

a 'tidyFit' R6 class.

data

a data frame, data frame extension (e.g. a tibble), or a lazy data frame (e.g. from dbplyr or dtplyr).

Details

Hyperparameters:

None. Cross validation not applicable.

Important method arguments (passed to m)

• max.paths (Number of paths to search)

The function provides a wrapper for gets::gets. See ?gets for more details.

Implementation

Print output is suppressed by default. Use 'print.searchinfo = TRUE' for print output.

Value

A fitted 'tidyFit' class model.
