Several software packages for the analysis of general agreement indices and association models are available. Only a few programs are mentioned here; an excellent overview can be found at the home page of J. Uebersax (2003). Outstanding programs are SAS (SAS, 2000) and LEM (Vermunt, 1997b). SAS is a powerful tool that allows the modeling of practically all possible loglinear models. LEM is a very flexible and easy-to-handle freeware program for the analysis of categorical data. All loglinear models presented in this chapter have been analyzed using LEM.
