Improved Confidence Intervals for the Variance and Standard Deviation of a Normal Population.
Abstract
Shortest confidence intervals for the variance of a normal population are found as superior alternatives to the widely used equal-tail confidence intervals. Extensive tables of high precision are presented which enable the user to construct easily minimum-length confidence intervals for the variance, the standard deviation, and shortest unbiased confidence intervals. Characteristics and improved performance of the alternative confidence intervals are discussed in detail and illustrated graphically, with an emphasis on the optimal distribution of complementary tail area between the upper and lower tails.
