fit.updated.formulas: Fit models after screening

Description

Fits the models that have been generated with screening using model.formulas.update.

Usage

fit.updated.formulas(formulas, X)

Value

Returns a list of length 2:

fitted.models

A list of length 4, containing the fitted Y-/L-/C- and A-models.

all.summaries

A list of length 4, containing the summary of the fitted Y-/L-/C- and A-models.

Arguments

formulas

An object returned by model.formulas.update

X

A data frame on which the model formulas should be evaluated

Details

Fits generalized (additive) linear models based on the screened model formula list generated by model.formulas.update.

# second: update these model formulas based on variable screening with LASSO

# then: fit and inspect the updated models
fitted.models <- fit.updated.formulas(glmnet.formulas, EFV)
