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 , min=var df/q(1+)/2 and max=var df/q_((1-alpha)/2) where var=Variance[list], df=Length[list]-1, and qi is the ith quantile of a 2 distribution with df degrees of freedom.
  • The following option can be given:
