poisson.ci {biostat3} | R Documentation |
A wrapper for the poisson.test
that allows for vector values.
poisson.ci(x, T = 1, conf.level = 0.95)
x |
number of events. |
T |
time base for event count. |
conf.level |
confidence level for the returned confidence interval. |
This uses stats::poisson.test
for the calculations.
A matrix (or vector) with columns giving lower and upper confidence limits for each parameter. These will be labelled as (1-level)/2 and 1 - (1-level)/2 in % (by default 2.5% and 97.5%).
