In IRTC: Marginal Maximum Likelihood Estimation for Item Response Models
data.sim.rasch R Documentation
Simulated Dichotomous Rasch Data
Description
A simulated dataset of dichotomous (0/1) item responses generated under the
Rasch model, provided as an example dataset for IRTC.
Usage
data(data.sim.rasch)
Format
A matrix with 2000 persons (rows) and 40 dichotomous items (columns), with
entries coded 0 or 1.
Details
The data were simulated with person abilities drawn from a standard normal
distribution and item difficulties spread evenly over [-2.2, 2.2].
The generating script is ‘scripts/gen_data.R’ in the package sources.
Source
Simulated by IRTC. See ‘scripts/gen_data.R’ in the package
sources for the reproducible generating code.
