# `causalis.scenarios.iv.refutation`

Refutation and diagnostic utilities for instrumental-variable scenarios.

This module includes checks for IV assumptions:

- First-stage strength: Is the instrument strongly correlated with the treatment?

- Instrument overlap: Is the instrument assignment well-spread across covariates?

- Confounder balance: Are covariates balanced across instrument groups?

- Reduced-form sanity: Does the instrument have an effect on the outcome?
