epicure: A Package of 5 Programs for Generalized Risk Modeling and Person-Year Computation

Programs for the anaylsis of medical, public health, epidemiologic, econometric, and reliability data

analysis of survival time studies, case-control studies, clinical trials, case-cohort studkes, radiation protection and quality control studies
general models - including additive, multiplicative, and geometric mixture models for absolute and relative risks
likelihood-based confidence bounds, profile likelihood evaluation and plots
quasi-likelihood estimates with user-defined variance functions
handles complex analytical problems such as those incolcing time-dependent covarites
detailed documentation and extensive examples

programs share a common command syntax
automatic generationof log and command scipt files for permanent session record and replication or modification of prior analyses
command scipts can be used in interactive sessions and can be nested
