The Open Epi Initiative: The types of calculations currently performed by OpenEpi include: OpenEpi has been reviewed, both by media organizations and in research journals. Once in the word processor you can change font sizes and make other modifications to the results.
Various confidence intervals for proportions, rates, standard mortality ratio, mean, median, and percentiles. Ninety five percent confidence intervals are the default, but users can select from a list of other confidence levels Ooenepi Figure 5.
For example, for a single two-by-two table, in addition to the conventional results presented in other programs, OpenEpi provides estimates for: The OpenEpi developers have had extensive experience in the development and testing of Epi Info, a program developed by the Centers for Disease Control and Prevention CDC and widely used around the world for data entry and analysis. OpenEpi was initially developed to perform analyses found in the disk operating system DOS version of Epi Info modules StatCalc and EpiTable, to improve on the types of analyses provided by these 2.31., and to provide a number of tools and calculations not currently available in Epi Info.
