Includes methods for selecting the best group using the Indifference-zone approach, as well as designs for non-inferiority, equivalence, and negative binomial models. For the sample size calculation for non-inferiority of vaccines, the approach is based on Fleming, Powers, and Huang (2021) . The Indifference-zone approach is based on Sobel and Huyett (1957) and Bechhofer, Santner, and Goldsman (1995, ISBN:978-0-471-57427-9). authors: - family-names: Aponte given-names: John J. email: john.j.aponte@gmail.com orcid: https://orcid.org/0000-0002-3014-3673 repository: https://johnaponte.r-universe.dev repository-code: https://github.com/johnaponte/ssutil commit: 80df74a1147036e9384a4a68a6b72433433bf486 url: https://johnaponte.github.io/ssutil/ date-released: '2025-06-10' contact: - family-names: Aponte given-names: John J. email: john.j.aponte@gmail.com orcid: https://orcid.org/0000-0002-3014-3673
