mc_dina_data_gen {variationalDCM}

Artificial data generating function for the multiple-choice DINA model based on the given Q-matrix

Description

mc_dina_data_gen() returns the artificially generated item response data for the MC-DINA model

Usage

Arguments

I

the number of assumed respondents

Q

the J \times K binary matrix

att_cor

the true value of the correlation among attributes (default: 0.1)

seed

the seed value used for random number generation (default: 17)

Value

A list including:

X

the generated artificial item response data

att_pat

the generated true vale of the attribute mastery pattern
