IRTsimrel: Reliability-Targeted Simulation for Item Response Data

A framework for reliability-targeted simulation studies in Item Response Theory (IRT). Researchers specify a target reliability level, and the package calibrates item discriminations to achieve that target.

Details

Main functions:

• eqc_calibrate: Empirical Quadrature Calibration (recommended)

• spc_calibrate: Stochastic Approximation Calibration

• sim_latentG: Generate latent ability distributions

• sim_item_params: Generate item parameters

• simulate_response_data: Generate response data
