LNRTQ: Log-normal response time modelling with variable person speed...

In LNIRT: LogNormal Response Time Item Response Theory Models

Description

Log-normal response time modelling with variable person speed (intercept, trend, quadratic)

Usage

LNRTQ(RT, X, data, XG = 1000, burnin = 10)

Arguments

RT	a Person-x-Item matrix of log-response times (time spent on solving an item).
X	explanatory (time) variables for random person speed (default: (1:N.items - 1)/N.items).
data	either a list or a simLNIRTQ object containing the response time matrix. If a simLNIRTQ object is provided, in the summary the simulated time parameters are shown alongside of the estimates. If the RT variable cannot be found in the list, or if no data object is given, then the RT variable is taken from the environment from which LNRTQ is called.
XG	the number of MCMC iterations to perform (default: 1000).
burnin	the percentage of MCMC iterations to discard as burn-in period (default: 10).

Value

an object of class LNRTQ.
