Likelihood Interval for Variance Ratio of Two Samples from Normal Distribution

Description

Likelihood interval for variance ratio of two samples assuming normal distribution. Likelihood function plot is also shown. For faster calculation speed, plot option '0' is recommended. Sample size is not allocated.

Arguments

num.data	a numeric vector of data values, variance value at the numerator position; mandatory
denom.data	a numeric vector of data values, variance value at the denominator position; mandatory
conf.level	confidence level for the interval estimation
df.t	temporary degree of freedom for likelihood interval, default is 2.4. Sample size ratio is considered for the final degree of freedom.
k	cutoff value for likelihood interval. If not specified, F-test is used.

Value

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