Information-Theoretic Approach for Moderation Analysis

Provides a robust implementation of information-theoretic moderation analysis using multi-model inference based on Akaike's Information Criterion (AIC) and its small-sample corrected form (Corrected AIC). The package enables researchers to compare competing model specifications and helps distinguish true interaction effects from nonlinear relationships that may produce spurious moderation. The methods build on Daryanto (2019) .

Information-Theoretic Approach for Moderation Analysis

📦 Overview

ModLR implements an information-theoretic framework for moderation analysis using multi-model inference based on Akaike's Information Criterion (AIC and AICc).

The package enables researchers to compare alternative moderation models and reduces the risk of identifying spurious moderation effects arising from nonlinear relationships.
