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