Subgroup Analysis

Acerca de

Streamlines the process of investigating how experimental effects vary across different participant or study clusters, providing a rigorous framework for research automation. This skill guides users through pre-specifying moderators, selecting appropriate statistical methods like meta-regression or interaction tests, and applying necessary corrections for multiple comparisons to ensure robust findings. It is particularly valuable for researchers looking to move beyond average treatment effects to understand the nuances of their data while avoiding common pitfalls like Type I error inflation and exploratory over-interpretation.
