gives a confidence interval for the ratio of the population variances estimated from and from .
- To use VarianceRatioCI, you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
- VarianceRatioCI[list1,list2] gives a confidence interval for a ratio of the population variances estimated by Variance[list1] and Variance[list2].
- For confidence level α, and where ratio=Variance[list1]/Variance[list2] and is the i quantile of an F-ratio distribution with Length[list1]-1 numerator and Length[list2]-1 denominator degrees of freedom.
- The following option can be given:
ConfidenceLevel 0.95 probability associated with a confidence interval
