Wald and Wilson confidence intervals for Poisson rates

Description

Compute a confidence interval for Poisson rates using the Wald and Wilson methods.

Usage

confIntRate(x, t, conf.level = 0.95)

confIntRateWald(x, t, conf.level = 0.95)

confIntRateWilson(x, t, conf.level = 0.95)

Arguments

x	Number of events.
t	Total observation time.
conf.level	Confidence level for confidence interval.

Value

confIntRate returns a data.frame with columns: x, t, type, rate, lower, upper.

confIntRateWaldreturns a matrix with columns rate, lower, and upper.

confIntRateWilson returns a matrix with columns rate, lower, and upper.
