Testing in Conditional Likelihood Context

An implementation of extended Rasch modeling hypothesis testing in R. Provides 4 statistical tests, i.e. gradient test (GR), likelihood ratio test (LR), Rao score or Lagrange multiplier test (RS), and Wald test, for testing a number of hypotheses referring to the Rasch model (RM), linear logistic test model (LLTM), rating scale model (RSM), and partial credit model (PCM).
