flat.log.linear: Fit an LLM

Description

Fit a log-linear model. This is a wrapper function for our own variant of the glm function, pirls.

Usage

flat.log.linear(pop, model.terms, rasch = FALSE)

Arguments

pop
The CRC data as a data frame.
model.terms
The columns of the standard design matrix to include in the model. For example, "c1", "c2" for main effects, and "c12" for interactions.
rasch
Logical: Is this the Rasch model?

Value

A vector of log-linear coefficients. The first coefficient is the intercept, and the rest correspond (in order) with the model.terms argument

Details

Maximum likelihood estimation is used, conditioning on the observed population as if it were the full population.
