Q.generate: Generation of Dichotomous Q-Matrix

In NPCDTools: The Nonparametric Classification Methods for Cognitive Diagnosis

Generation of Dichotomous Q-Matrix

Description

The function generates a complete Q-matrix based on a pre-specified probability of getting a one.

Usage

Q.generate(K, J, p, single.att = TRUE)

Arguments

K	The number of attributes
J	The number of items
p	The probability of getting a one in the Q-matrix
single.att	Whether all the single attribute patterns are included. If T, the completeness of the Q-matrix is guaranteed.

Value

The function returns a complete dichotomous Q-matrix

Examples

q = Q.generate(3,20,0.5,single.att = TRUE)
q1 = Q.generate(5,30,0.6,single.att = FALSE)
