In LBI: Likelihood Based Inference

Likelihood Interval for a Proportion or a Binomial Distribution

Description

Likelihood interval of a proportion in one group

Usage

  LIbin(y, n, k, conf.level=0.95, eps=1e-8)

Arguments

y	positive event count of a group
n	total count of a group
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 a proportion in one group. The likelihood interval is asymmetric and there is no standard error in the output. If you need percent scale, multiply the output by 100.

Value

y	positive (concerning) event count
n	total trial count
PE	point estimation for the proportion
LL	lower limit of likelihood interval
UL	upper limit of likelihood interval
