causalkit.eda.eda.CausalEDA.positivity_check

CausalEDA.positivity_check(ps=None, bounds=(0.05, 0.95))

Check overlap/positivity based on propensity score thresholds.

Returns a dict with: - bounds: (low, high) thresholds used - share_below: fraction with PS < low - share_above: fraction with PS > high - flag: heuristic boolean True if the tails collectively exceed ~2%

Return type:

Dict[str, Any]

Parameters:

• ps (ndarray | None)

• bounds (Tuple[float, float])
