#' Goodness-of-fit of the user-defined weight matrix of the linear logistic test model
#'
#' The linear logistic test model (LLTM, Fischer, 1973) is estimated as a restricted Rasch model. For the LLTM, the user has to set up a design matrix. To assess the fit of this user-defined weight matrix, a method is proposed by Baghaei and Hohensinn (submitted) which is analogous to the parallel analysis in factor analysis.
#'
#' This package allows to conduct this proposed approach for an LLTM.
