gee_fit: GEE fitting function

In tidymodels/multilevelmod: Model Wrappers for Multi-Level Models

GEE fitting function

Description

Custom fitting function to add GEE model with cluster variable to parsnip GEE function call.

Usage

gee_fit(formula, data, family = gaussian, ...)

Arguments

formula	Normal formula but uses the gee_formula() internal function for the id_var() specification for clustering.
data	Modeling data
family	a family object: a list of functions and expressions for defining link and variance functions. Families supported in gee are gaussian, binomial, poisson, Gamma, and quasi; see the glm and family documentation. Some links are not currently available: 1/mu^2 and sqrt have not been hard-coded in the cgee engine at present. The inverse gaussian variance function is not available. All combinations of remaining functions can be obtained either by family selection or by the use of quasi.
...	For additional parameters

Details

gee() always prints out warnings and output even when silent = TRUE. gee_fit() will never produce output, even if silent = FALSE.

Also, because of issues with the gee() function, a supplementary call to glm() is needed to get the rank and QR decomposition objects so that predict() can be used.

Value

A gee object
