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.
