VarianceRatioCI


gives a confidence interval for the ratio of the population variances estimated from and from .
  • gives a confidence interval for a ratio of the population variances estimated by Variance and Variance.
  • For confidence level , and where ratio=Variance[list1]/Variance[list2] and is the i^(th) quantile of an F-ratio distribution with Length[list1]-1 numerator and Length[list2]-1 denominator degrees of freedom.
