PowerSimulate

PowerSimulate is a collection of compact R Shiny applications designed to perform simulation-based statistical power analysis.

Although there are more straightforward tools for power analysis in simple tests such as correlations, t-tests and ANOVA, these applications are based exclusively on simulations. They serve as an educational tool to demonstrate the concept of statistical power, but also as a platform to show the importance of simulation-based power analysis for more complex designs.

Shiny App Iframe

All applications are available on my (rather slow) Shiny personal server. However, if it runs too slow or my server doesn’t work, you can always run it locally on your computer with R installed. Just open the link to the code on GitHub (Correlation, Independent t-test, Paired t-test), and you’ll find instructions there.
