Description

SampSize is an application to assist in the design of clinical trials by calculating the sample size using inputs provided by the user.

Features calculations for:

- Normal and binary endpoints
- Parallel and crossover designs
- Superiority, Non-Inferiority, Equivalence, Bio-equivalence and Precision objectives

SampSize calculates either the required sample size for a desired power, or calculates the power of a trial for a given sample size. It allows users to specify inputs such as significance level, power, mean difference (or limit), standard deviation, and the allocation ratio.

Developed in collaboration with Dr Steven A Julious, Medical Statistics Group, School of Health and Related Research, The University of Sheffield.
