Update probability distribution applying multiplicative rule

Description

kmassessmultiplicative updates a probability distribution on a knowledge structure according to the multiplicative rule.

Usage

kmassessmultiplicative(probs, ks, zeta0, zeta1, question, response)

Arguments

probs	Probability distribution over the knowledge structure (vector)
ks	Binary matrix of the knowledge structure
zeta0	Vector of update parameters for wrong responses
zeta1	Vector of update parameters for correct responses
question	Item that has been posed
response	Correctness of received response (0 or 1)

Value

Updated probability vector
