VarianceRatioCI
VarianceRatioCI[list1,list2]
gives a confidence interval for the ratio of the population variances estimated from list1 and from list2.
Details and Options
- To use VarianceRatioCI, you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
- VarianceRatioCI[list1,list2] gives a confidence interval {min,max} for a ratio of the population variances estimated by Variance[list1] and Variance[list2].
- For confidence level α, min=ratio/q(1+α)/2 and max=ratio/q(1-α)/2 where ratio=Variance[list1]/Variance[list2] and qi 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
