Can someone tell me if SAS has a procedure to calculate two-sided tolerance intervals, based on sampling, for a normal distribution that contains the central p-content of that distribution for some given confidence? These are different than the two-sided tolerance intervals that merely contain p-content of the distribution. D. B. Owen (1964) "Control of Percentages in Both Tails of the Normal Distribution," Technometrics is a good reference, as is the Krishnamoorthy and Mathew (2009) text book Statistical Tolerance Regions (see Chapter 2, and Table B3 in appendix.) Appreciate any help!
