qmatrix.test.interaction


This data set list 1s and 0s indicating relation between items and attributes. This matrix specifies which items are required
 for mastery of each attribute (i.e., latent variable). The matrix must be a size of <code>nitems X nattributes</code>


Analysis of dichotomous response data to obtain attribute profile
estimates for respondents using Diagnostic Classification Model (DCM) and
Markov Chain Monte Carlo (MCMC) method. The estimation procedure uses a
loglinear cognitive diagnostic modeling (LDCM) framework that allows for
the estimation of a host of DCMs such as NIDO, NIDA, NC-RUM etc.
