This repository contains a R/Shiny app to obtain sample sizes for optimal design for univariate regression-based norming, as described in Innocenti et al. (2023, Psychological Methods, 28(1), 89–106. https://doi.org/10.1037/met0000394)
To run the code you would need:
-
An installation of R (https://cran.r-project.org/bin/windows/base/)
-
With a shiny library (install.packages("shiny")).
-
Then run this code:
shiny::runGitHub('FInnocenti-Stat/ShinyApp_OD_Univariate_Norming')
