更多信息和选项
- To use VarianceCI, you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
- VarianceCI[list] gives a confidence interval {min,max} for the population variance estimated from list.
- For confidence level α, min=var df/q(1+α)/2 and max=var df/q(1-α)/2 where var=Variance[list], df=Length[list]-1, and qi is the i
quantile of a 
distribution with df degrees of freedom. - The following option can be given:
-
ConfidenceLevel 0.95 probability associated with a confidence interval
