Equivalence Testing the Easy Way

Abstract

The purpose of the article is to demonstrate an equivalence testing software application written under SAS^1 Institute software designed for use by pharmaceutical and other medical research professionals. Besides making the entire equivalence testing procedure easier and more efficient, the application “EquivEasy” offers three main advantages over similar software: a) testing for 3 x 3 in addition to 2 x 2 crossover designs, b) familiar SAS user environment, and c) export flexibility (MS Word, PDF, HTML). Two case studies are presented with report results provided in tabular and graphical form.
