In irtoys: A Collection of Functions Related to Item Response Theory (IRT)
tsc R Documentation
True scores with standard errors
Description
Computes the IRT true scores (test response function at the estimated
ability) and an estimate of their standard error via the delta theorem,
treating item parameters as known).
Usage
tsc(ip, theta)
Arguments
ip
Item parameters: the output of est, or a 3-column matrix
corresponding to its first element, est.
theta
An object containing ability estimates, as output by function
mlebme or eap
Value
A matrix with the true scores in column 1, and their standard errors
of measurement (SEM) in column 2

Examples
th <- mlebme(resp=Scored, ip=Scored2pl)
tsc(Scored2pl, th)
