Project Organization

The code for this project is divided across four branches:

main (current branch)         <- all of the data and analysis code
calibration                   <- software for the calibration experiment
validation-A                  <- software for the validation experiment (short-forms)
validation-B                  <- software for the validation experiment (long-forms)

The organization of the main branch (current branch) is as follows:

├── 01_Priors                   <- Data from pilot experiments.
├── 02_Design                   <- Parameter recovery studies for IRT models.
├── 03_Calibration              <- Data and code for the MaRs-IB calibration study. 
├── 04_Validation               <- Data and code for the MaRs-IB validation study. 
├── 05_Figures                  <- Figures for presentations & manuscript.
├── manuscript                  <- LaTeX code for the manuscript.
├── tutorials                   <- MaRs-IB item parameters, short forms, and optimal assembly tutorials.

MaRs-IB Stimuli

The actual stimuli of the MaRs-IB are publicly available at this OSF repository.
