AN EPIDEMIOLOGIC CALCULATOR SUPPORTING SPANISH SPEAKING VETERINARIANS IN A RESOURCE-LIMITED COMPUTING ENVIRONMENT

ABSTRACT: Statistical analysis is fundamental to the field of epidemiologic research. How - ever, commercial statistical software packages are very expensive for personal use. Some free packages are available from the Internet, but researchers do not always have access to a computer for installing such software as they like. The authors developed an epidemio - logic calculator, enabling sample size calculations as well as simple analyses, for Spanish speaking veterinarians in a resource-limited computing environment. There are at least four advantages to using the calculator, such as (1) no installation required, (2) no on-line connec - tion required during the calculation process, (3) the open-source attitude, and (4) the public- domain attitude.
