rm_interpreter {mmirestriktor}

Interpret Results of Restricted Means Analysis

Description

This function provides a human-readable interpretation of the results of a restricted means analysis. It compares the original (unconstrained) and reduced (restricted) R-squared values to evaluate the imposed constraints. It also returns the Generalized Order-Restricted Information Criterion (GORIC) which can be used for model comparison.

Usage

rm_interpreter(rm_res)

Arguments

rm_res

An object of class 'restriktor', typically the result of a call to restriktor.

Value

A character string with an interpretation of the analysis results, including the R-squared values, their reduction, and the Generalized Order-Restricted Information Criterion (GORIC) if available.
