The Loglinear Analysis MT application module (LOGLIN) contains procedures for the analysis of categorical data using loglinear analysis. This application is thread-safe and takes advantage of structures.
The estimation is based on the assumption that the cells of the K-way table are independent Poisson random variables. The parameters are found by applying the Newton-Raphson method using an algorithm found in A. Agresti (1984) Analysis of Ordinal Categorical Data.
You may construct your own design matrix or use LOGLIN procedures to compute one for you. You may also select the type of constraint and the parameters.
Fits a hierarchical model given fit configurations
Will fit all 3-way hierarchical models of a table
Provides for cell weights
LOGLIN can estimate most of the models described in such texts as Y.M.M. Bishop, S.E. Fienberg, and P.W. Holland (1975) Discrete Multivariate Analysis, S. Haberman (1979) Analysis of Qualitative Data, Vols. 1 and 2, as well as the book by A. Agresti.
Platform: Windows, Mac and Linux.
Requirements: GAUSS/GAUSS Light version 8.0 or higher.
