short_poly_data {autoRasch}

A Shorter Inhomogenous Polytomous Dataset

Description

The artificial dataset of a polytomous responses (three categories) which contains three subsets with different discrimination values. To reproduce this dataset:
short_poly_data <- generate_data(alpha = c(0.02,0.5,2), nitem = 3, ndim = 3,ncat = 5, theta = c(-6,6), beta = c(-4,4), ntheta = 151)

will lead to similar but not the same dataset, due to the randomization.

Usage

data(short_poly_data)

Format

An object of class data.frame with 151 rows and 9 columns.
