Exact Confidence Interval for binomial proportions.


This package calculates the Confidence Interval (CI) for single binomial proportion, CI for difference of two binomial proportions, and CI for difference of difference. There are 4 major functions available: singleCI(k,n) gives the CI for binomial proportion given (k,n), pdiff(k1,n1,k2,n2, d) gives the probability that the difference of p1 from p2 is greater than d, and pdiffCI(k1,n1, k2,n2) gives the CI for difference of two binomial proportions given (k1,n1, k2, n2). numCI(k1,n1, k2,n2, K1, N1,K2,N2) gives the CI for difference of difference (p1-p2) - (P1-P2). At default, a uniform priori distribution of p is assumed. You may also specify the priori distribution parameter a0, b0 by assuming p follows a nonuniform beta distribution beta(a0, b0). Note that boost header files are needed to build the package.
