Moderation Analysis
Test when X's effect on Y strengthens or weakens depending on a moderator variable. A complete moderation report with simple slopes, an interaction plot, and APA-format reporting — the equivalent of SPSS Process/Hayes.
Interaction Term (X×W)
Using the Aiken & West (1991) centering standard, the effects of X, W, and the interaction term are each calculated separately.
Simple Slopes
X's effect on Y is reported separately at low/mean/high (or 2-category) levels of W.
Interaction Plot
A visual chart showing how the X-Y relationship changes across levels of W is generated automatically.
