Equivalence test using two one-sided tests are widely used for demonstrating the comparability of treatment effects in different research fields. The method described in the manuscript aims to use simulations in Microsoft Excel to compute power for 2 one-sided tests for two groups with unequal variances.
One of the main purposes of stability testing is to establish shelf life for these drug products. The goal of this paper is to create an Excel spreadsheet, which can be used for statistical testing of more than three stability batches for poolability.
