Abstract
The XLISP-Stat statistics system is convenient for implementing new
statistical methods as it is freely available, reasonably fast and
contains a powerful programming language and support for dynamic
graphics.  An object-oriented system for modelling longitudinal data
using Generalised Estimating Equations has been developed in
XLISP-Stat and will be presented. The system includes a wide range of
choice for link function, error function and working correlation
model. Design matrices can be constructed using a model formula
specification for factor and metric variables and their
interactions. Diagnostic plots are also available which make use of
the dynamic graphics features of XLISP-Stat to link diagnostics for
different variables and for different observations on an individual.
