See CAPINT1 in the SAS/QC Sample LibraryYou can specify options after the slash (/) in the INTERVALS statement to control the computation and printing of intervals. The following statements produce a table of one-sided lower prediction limits for the mean, which is displayed in Figure 5.26:
title 'Statistical Intervals for Fluid Weight'; proc capability data=Cans noprint; intervals Weight / methods = 1 2 type = lower; run;
The METHODS= option specifies which intervals to compute, and the TYPE= option requests one-sided lower limits. All the options available in the INTERVALS statement are listed in Summary of Options and are described in Dictionary of Options.
