Confidence Intervals for Comparisons of Binomial or Poisson Rates

Computes confidence intervals for the rate (or risk) difference ("RD") or rate ratio (or relative risk, "RR") for binomial proportions or Poisson rates, or for odds ratio ("OR", binomial only). Also confidence intervals for a single binomial or Poisson rate, and intervals for matched pairs. Includes asymptotic score methods including skewness corrections, which have been developed in Laud (2017, in press) from Miettinen & Nurminen (1985) <doi:10.1002/sim.4780040211> and Gart & Nam (1988) <doi:10.2307/2531848>. Also includes MOVER methods (Method Of Variance Estimates Recovery), derived from the Newcombe method but using equal-tailed Jeffreys intervals, and generalised for incorporating prior information. Also methods for stratified calculations (e.g. meta-analysis), either assuming fixed effects or incorporating stratum heterogeneity.
