The {ordinalsimr} package assists in constructing simulation studies of ordinal data comparing two groups. It is intended to facilitate translation of methodological advances into practical settings for e.g. applied statisticians and data analysts who want to determine an appropriate statistical test to apply on their data or a proposed distribution of data.
This package is primarily developed as a Shiny application which
abstracts away the heavier coding aspect of setting up simulation
studies. Instead, users can simply enter parameters and data
distributions into the application, and save the results as an .rds
file. The structure of the Shiny application only allows for one
simulation to be specified at a time as opposed to a grid of parameters.
However, the underlying functions for running the simulations are
accessible. See vignette("ordinalsimr") for template code on setting
up your own simulations manually.
You can install the development version of ordinalsimr from GitHub with:
# install.packages("devtools")
devtools::install_github(
"NeuroShepherd/ordinalsimr",
force = TRUE,
build_vignettes = TRUE
)The application is available at [link], but may be down due to account usage limitations on ShinyApps.io. There is not currently a plan to increase the usage limits so it is strongly recommended that you run the application locally.
Informative progressive bars have not been implemented in the Shiny application, but a simulation that fails to run will almost always fail at the beginning rather than in the middle of the run. Simulations with 1000s of iterations will take minutes to hours to run.
