Methodological report reveals unified computational tools for probing interaction effects across diverse statistical models, highlighting accessible online testing and visualization for researchers.

Key Points

Review statistical methods for probing interaction effects and introduce a unified suite of accessible online computational tools across linear regression, multilevel modeling, and latent curve analysis.
Synthesized mathematical approaches for probing moderation, including simple slopes tests, regions of significance, and confidence bands across moderator distributions.
Engineered a unified collection of freely available web-based software utilities supporting multiple linear regression, hierarchical linear modeling, and latent curve analysis.
Automated the calculation of significance tests for simple slopes, regions of significance, and confidence bands, eliminating tedious and error-prone manual calculations.
Provided integrated plotting utilities to directly visualize conditional relationships and interaction effects across continuous moderator values.
