LLAMA: an Object-Oriented System for Log Multiplicative Models
David R. Firth · COMPSTAT · 1998
Llama is an interactive environment, implemented in XLISP-STAT, for the specification and fitting of log linear and log multiplicative models to contingency tables. This paper describes the model syntax and object-oriented design of Llama, and some statistical and algorithmic features including the use of over-parameterized representations of models.
