Implements Computerized Adaptive Testing Simulations

Computerized Adaptive Testing simulations with dichotomous and polytomous items. Selects items with Maximum Fisher Information method or randomly, with or without constraints (content balancing and item exposure control). Evaluates the simulation results in terms of precision, item exposure, and test length. Inspired on Magis & Barrada (2017) .

simCAT

simCAT implements Computerized Adaptive Testing simulations with dichotomous items. The program selects items with Maximum Fisher Information method or randomly, with or without constraints (content balancing and item exposure control).

To install simCAT, use:

devtools::install_github('alexandrejaloto/simCAT')

To simulate using a friendly interface, use:

simCAT::sim.shiny()
