Example map validation analyses using simulated data. For additional resources, see .
01-sim-data.R includes functions to simulate MIRT and LCDM data when using a simple Q-matrix desing.
02-estimate-models.R includes code for estimating MIRT, LCDM, and LCA models using rstan. The code for the Stan models can be found in stan-models/.
03-map-validation.R includes code for running the map validation analyses including posterior predictive model checks, attriubte mastery, and attribute difficulty.
04-extra-viz.R includes code for generating other graphics in the presentation.
