poly_inh_dset {autoRasch}

The Inhomogenous Polytomous Dataset

Description

The artificial dataset of a polytomous responses (five categories) which contains three subsets with different discrimination values. To reproduce this dataset:
poly_inh_dset <- generate_data(responseType = "discriminate", ncat = 5, alpha = c(0.04,0.045,0.05,0.055,0.06,0.065,0.2,0.25,0.3,0.35,0.4,0.45,2.6,2.65,2.7,2.75,2.8,2.85,2.9))

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

Usage

data(poly_inh_dset)

Format

An object of class data.frame with 301 rows and 18 columns.
