VarianceCI

VarianceCI[list]
gives a confidence interval for the population variance estimated from list.
  • VarianceCI[list] gives a confidence interval {min, max} for the population variance estimated from list.
  • For confidence level Alpha, min=var df/q(1+Alpha)/2 and max=var df/q(1-Alpha)/2 where var=Variance[list], df=Length[list]-1, and qi is the i^(th) quantile of a Chi2 distribution with df degrees of freedom.
  • The following option can be given:
