In NPCDTools: The Nonparametric Classification Methods for Cognitive Diagnosis
Q.generate R Documentation
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)
