Software

R package anomo

This package implements the statistical power formulas for the equivalence test of two-group means. It also provides the Monte Carlo confidence interval (MCCI) that can be used to test difference or equivalence.

R package odr

This package is to help researchers design cost-efficient and effective (multilevel) experiments investigating main, mediation, and moderation effects by (a) solving optimal sample allocations that use the minimum budget to achieve adequate power; (b) comparing design efficiency between different sample allocations; and (c) explicitly accommodating costs and budget in power analyses.
