LInormVar {LBI}

Likelihood Interval of sd and variance assuming Norml Distribution

Description

Likelihood interval of sd and variance assuming normal distribution. This is estimated likelihood interval, not profile likelihood interval.

Usage

  LInormVar(x, k, conf.level=0.95)

Arguments

x

a vector of observation

k

1/k likelihood interval will be calculated

conf.level

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

Details

It calculates likelihood interval of sd and variance assuming normal distribution in one group. The likelihood interval is asymmetric and there is no standard error in the output.

Value

PE

point estimation for the proportion

LL

lower limit of likelihood interval

UL

upper limit of likelihood interval
