Statistical Software Components from Boston College Department of Economics

Abstract: ndbci computes rates and Poisson confidence intervals for a single variable. In contrast to Stata's ci, ndbci calculates rates and confidence intervals for each level of a grouping variable. ndbci allows formatting of the output and naming of the group and outcome variables. ndbci also formats output for 1, 10, 100, 1000, 10000 and 100000 person years.

Language: Stata
Requires: Stata version 8.2
