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