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.
The actual stimuli of the MaRs-IB are publicly available at this OSF repository.
This project was made possible with support from the National Center for Advancing Translational Sciences (NCATS), a component of the National Institute of Health (NIH), under award number UL1TR003017.
