GetProbCorrectNcrum(pi.i.star.prime, r.ia.star, q.ia, alphas)
Arguments
pi.i.star.prime
a numeric value for the probability of a correct response for item i given
that no attributes have been mastered.
r.ia.star
a numeric 1 x nattributes vector of the penalty probabilities for this item of a correct response
for each required attribute that has not been mastered.
q.ia
a numeric 1 x nattributes vector of the qmatrix entries for the given item.
alphas
