simPsyStudy - Simulation of Ordinal Responses for Psychometric Studies
Provides tools to define factorial simulation conditions
and generate binary or ordinal item responses under
common-factor and probit graded response model
parameterizations. Supports multivariate normal and correlated
gamma latent traits, reproducible replications, parameter
conversion, and structured storage of generated datasets. The
graded response model follows Samejima (1969).
