Likelihood Interval for Variance of Single Sample from Normal Distribution

Description

Likelihood interval for variance of single sample assuming normal distribution. Likelihood function plot is also shown. For faster calculation speed, plot option '0' is recommended.

Arguments

data	a numeric vector of data values; mandatory
conf.level	confidence level for the interval estimation
df	degree of freedom for likelihood interval; default is 1.2
k	cutoff value for likelihood interval. If not specified, F-test is used.

Value

demo	basic demographics of data
LI	estimated interval of variance by LI
LI.sd	estimated interval of standard deviation by LI
CI	estimated interval of variance by CI
plot	likelihood-related plots
