Generalized linear mixed-effects model for tidyfit

Fits a linear or logistic mixed-effects model (GLMM) on a 'tidyFit' R6 class. The function can be used with regress and classify.

Usage

# S3 method for glmm
.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).

Value

A fitted 'tidyFit' class model.

Details

Hyperparameters:

None. Cross validation not applicable.

Important method arguments (passed to m)

The function provides a wrapper for lme4::glmer. See ?glmer for more details.

Implementation

No implementation notes

# Load data
data <- tidyfit::Factor_Industry_Returns
data$Return <- ifelse(data$Return > 0, 1, 0)

# Estimate model with random effects
fit <- classify(data, Return ~ CMA + (CMA | Industry), logit = m("glmm"),
                .mask = "Date")
