Other software to calculate Information-Based Measure of Disagreement

The PAIRSetc, a program that compares matched observations and is part of the freeware Winpepi1,2 suite of programs for epidemiologists.

The PAIRSetc provides the information-based measure of disagreement3 by modules D1 and D3 (for paired observations) and module I1 (for pairwise comparisons in a group of 3-10 matched observations). An option is offered for confidence-interval estimation.

PAIRSetc is a portable stand-alone program, and does not require installation.
