1 | riskratio.conf(x, n, plot = TRUE, conf.level = 0.95, log = "")
|
x |
a vector of counts of successes in each independent sample |
n |
a vector of the number of trials in each independent sample |
plot |
whether to plot the confidence density and curve |
conf.level |
the confidence level for the confidence interval indicated on the confidence curve |
log |
'x' to plot risk ratio on log-scale |
A list containing the confidence functions pconf, dconf, cconf, and qconf for the relative risk between two proportions, as well as the P-curve and S-curve.
