spacr.regression_search

Preserve the deprecated spacr.regression_search import path.

The module was renamed when the sweep became a spaCR module in its own right (“Parameter Sweep”) rather than a script beside the regression. Importing this name still works so nothing written against it breaks; it re-exports the new API and nothing else.

The alias emits one DeprecationWarning per import. New code should import spacr.parameter_sweep and use SweepSpace, run_sweep, and summarise_sweep directly.
