Demonstrated Insensitivity to Bias in 2x2xK Contingency Tables

Description

For an observational study with binary treatment, binary outcome and K strata, implements a d-statistic that uses those strata most insensitive to unmeasured bias in treatment assignment.<doi:10.1093/biomet/asaa032> The package has one function, dstat2x2xk.

There is one function, dstat2x2xk, intended to increase design sensitivity when analyzing a 2x2xk table, treatment x binary outcome x strata, from an observational study. See Rosenbaum (2022).
