LIpois {LBI}

Likelihood Interval of the Mean assuming Poisson Distribution

Description

Likelihood interval of lambda assuming Poisson distribution.

Usage

  LIpois(x, k, conf.level=0.95, eps=1e-8)

Arguments

x

mean or lambda, the count in a time unit.

k

1/k likelihood interval will be calculated

conf.level

approximately corresponding confidence level. If k is specified, this is ignored.

eps

Values less than eps are considered as 0.

Details

It calculates likelihood interval of mean(lambda) assuming Poisson distribution. The likelihood interval is asymmetric and there is no standard error in the output.

Value

PE

point estimation for the lambda

LL

lower limit of likelihood interval

UL

upper limit of likelihood interval
