A methods to compute a confidence interval for a risk ratio
is provided. The method is based on a Wald interval for the log risk
ratio. Used by confIntDiagnostic
confIntRiskRatio(x, n, conf.level = 0.95)
x |
vector of length 2, number of successes in each group. |
n |
vector of length 2, total number of trials in each group. |
conf.level |
