In SICSresearch/IRTpp_old: Estimating IRT parameters using the IRT Methodology

Description

Usage

irtpp(dataset = NULL, model, dims = 1, initialvalues = NULL,
  filename = NULL, output = NULL, restricted.items = c(), m)

Arguments

dataset	The matrix with the responses from the individuals
model	The model used to calibrate the parameters
dims	The dimensions to use on the estimation, remember to use the initial parameters if you want highquality estimation
initialvalues	The matrix with the initial values for the optimization process
filename	Optional argument specifying a CSV file to read instead of a dataset in memory
output	Optional. Additonal arguments that need to be documented by cristian
fixeditems	Optional. Items to fix.
