Module variables 

BIDS variable types: simple, sparse-run, and dense-run.

Implements the three variable types used in BIDS statistical modeling: SimpleVariable (participant/session-level), SparseRunVariable (event-level with onset/duration), and DenseRunVariable (continuous regressors sampled at TR).

Structs

DenseRunVariable

A dense run variable with uniformly-sampled time series data.

SimpleVariable

A simple variable with no timing information.

SparseRunVariable

A sparse run variable representing events with onset, duration, and amplitude.

Functions

apply_grouped

Apply a function to groups defined by a grouper.

get_grouper

Get a grouper key for groupby operations.

merge_simple

Merge a list of simple variables with the same name.

merge_sparse

Merge sparse run variables.
