The CAPABILITY Procedure

Summary of Options

The following tables list the PPPLOT statement options by function. For complete descriptions, see the section Dictionary of Options.

Distribution Options

Table 5.53 summarizes the options for requesting a specific theoretical distribution.

Table 5.53 Options for Specifying a Theoretical Distribution

Option

Description

BETA(beta-options)

specifies beta P-P plot

EXPONENTIAL(exponential-options)

specifies exponential P-P plot

GAMMA(gamma-options)

specifies gamma P-P plot

LOGNORMAL(lognormal-options)

specifies lognormal P-P plot

NORMAL(normal-options)

specifies normal P-P plot

WEIBULL(Weibull-options)

specifies Weibull P-P plot

Table 5.54 summarizes options that specify distribution parameters and control the display of the diagonal distribution reference line. Specify these options in parentheses after the distribution option. For example, the following statements use the NORMAL option to request a normal P-P plot:

proc capability data=measures;
   ppplot length / normal(mu=10 sigma=0.3 color=red);
run;

The MU= and SIGMA= normal-options specify and for the normal distribution, and the COLOR= normal-option specifies the color for the line.
