mmibain

The Mighty Metrika Interface to BAIN (‘mmibain’) R package provides Shiny apps to explore basic functionality of the ‘bain’ package for BAyesian INformative Hypotheses Evaluation.

Installation

You can install the released version of ‘mmibain’ from CRAN:

install.packages("mmibain")

You can install the development version of ‘mmibain’ from GitHub with:

# install.packages("devtools")
devtools::install_github("mightymetrika/mmibain")

Play RepliCrisis

‘RepliCrisis’ is a Shiny app game that simulates evalutating replication studies based on the framework presented in Hoijtink, Mulder, van Lissa & Gu (2019). Follow these steps to play:

• Set your sample size (for groups within study), difficulty, alpha level, and seed for reproducibility.
• Define thresholds for the Bayes Factor and Posterior Model Probability to assess evidence in favor of the original study.
• Conduct the original study to generate data and form a hypothesis.
• Show diagnostics and descriptives to understand statistical results and hypotheses.
• Conduct a replication study, using swap controls to match the original study’s results.
• Run replication analysis to evaluate the results against the original hypothesis.
• Start a new game by conducting a new original study.

To play, load ‘mmibain’ and call the RepliCrisis() function:

library(mmibain)
RepliCrisis()

mmibain Shiny App

The package also includes a Shiny app for running basic bain::bain() models:

• Upload your data in CSV format.
• Choose your modeling engine (lm, t_test, lavaan).
• Input your model and any additional arguments.
• Fit the model and input hypotheses for evaluation.
• Adjust settings such as the fraction parameter, standardized regression coefficients, and confidence intervals.
• Set a seed for reproducible results.
• Run the Bayesian Informative Hypotheses Evaluation.

Launch the app with:

mmibain()
