thetaScore R Documentation
thetaScore
Description
Return score (O-E) at theta. Used in estimation of theta by minimising
raw score - expected score at theta
Usage
thetaScore(theta, responses, itemParams, perfAdjust = 0.3)
Arguments
theta
a scalar value of theta.
responses
a vector of item responses for one case (can contain NA). Responses are in the same order as items
itemParams
a list of item designs (each used in a call to simplef). Must be of same length as responses.
perfAdjust
the correction factor for zeros and perfects to be add/subtracted from the raw score.
Value
a double, the score (O-E) at theta.
