sensitivityIxJ: Exact, Nonparametric Sensitivity Analysis for Observational Studies of Contingency Tables

The R package sensitivityIxJ provides exact and nonparametric sensitivity analysis methods for multi-category contingency tables under unmeasured confounding. It generalizes classical binary-treatment sensitivity analysis frameworks to I×J categorical settings.

The package accompanies the paper “Exact, Nonparametric Sensitivity Analysis for Observational Studies of Contingency Tables” by Elaine K. Chiu and Hyunseung Kang.
