Egret: Overview
The most user-friendly statistical package for epidemiologists is completely redesigned to take full advantage of Windows 95/98 and NT/2000.
Comprehensive Set of Models:
Many Not Available Elsewhere
Contingency tables
Logistic regression
Conditional logistic regression*
Logistic regression with random effects
Beta-binomial regression
Poisson regression
Weibull regression
Exponential regression
Cox proportional hazards regression
Cox regression with time-dependent covariates
Kaplan-Meier analysis and plots
Extensive post-fit analysis with plots, including delta-betas, hazard functions, and more.
Plus a new spreadsheet-based data editor and a statistical scratchpad
Unlike other epidemiology software, Egret permits the case/control ratio to vary over strata without using an approximation for the conditional likelihood function.
Bonus! EpiXact is now built into Egret
Cytel’s unique module for exact contingency table analysis for small-samples.
Odds ratio inference
Exact test of homogeneity for odds ratios
Exact test of unity for the common odds ratio
Exact confidence interval for the common odds ratio
Exact test of trend for k ordered binomial populations
Exact test of independence for k unordered binomial populations
Monte Carlo importance sampling option for difficult computations
