Module node 

Analysis nodes and edges in a BIDS-StatsModels graph.

Each node represents a statistical analysis step at a specific level of the BIDS hierarchy. Nodes contain a model specification, variable transformations, contrast definitions, and grouping criteria. They produce StatsModelsNodeOutputs containing design matrices and contrast information.

StatsModelsNode

A single analysis node in a BIDS-StatsModel graph.
