Simulate data for log-normal response time IRT modelling

Description

Simulate data for log-normal response time IRT modelling

Usage

Arguments

N

the number of persons.

K

the number of items.

rho

the correlation between the person ability and person speed parameter.

td

set time-discrimination to one (default: false).

WL

define the time-discrimination parameter as measurement error variance parameter (default: false).

kpa

the number of predictors for the person ability parameters (optional).

kpt

the number of predictors for the person speed parameters (optional).

kia

the number of predictors for the item-difficulty parameters (optional).

kit

the number of predictors for the item time intensity parameters (optional).

Value

an object of class simLNIRT.
