In beckerbenj/eatAnalysis: Convenience function for various analysis types
item.logit R Documentation
Simulates 1PL or 2PL responses
Description
Simulates responses following a 1PL or 2PL model given item parameters assuming normally distributed person parameters.
Usage
item.logit(z, slope = 1, thr)
Arguments
z
A vector of item difficulties.
slope
A vector of item discrimination parameters. Default is 1 and equals a 1PL model.
thr
A vector of item threshold parameters.
Value
A list with two matrices. First matrix includes the responses, seconds matrix includes the correct response probabilities.
