dstat-package: dstat

Description

dstat

Details

The DESCRIPTION file: dstat dstat The package provides a sensitivity analysis for a conditional test of the null hypothesis of no treatment effect in a matched observational study in which the unmeasured bias in treatment assignment is quantified by a sensitivity parameter gamma>=1. The test uses only those categories of pairs that demonstrate insensitivity to a bias of magnitude gamma, correcting for data-dependent selection of categories by conditional inference. The main function in the package is dstat().
