LBI (version 0.2.2)

LIbin: 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)

Value

y

positive (concerning) event count

n

total trial count

PE

maximum likelihood estimate on the proportion

LL

lower limit of likelihood interval

UL

upper limit of likelihood interval

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.
