Simulation for determining test reliability of sparse data sets
This script simulates binary responses to K items for N subjects. To run the simulation do the following.
Step 1
Instaal the latest version of R.
Step 2
Run simulation.r. You can change paramaters if you want and also run different scenario's in regard to item bank size, number of subjects or sampled items.
This generates a results.xlsx file with all variables for each scenario.
Step 3
Run visualisations.r to generate a graph for a single scenario.
