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
GUMBEL(Gumbel-options)	specifies Gumbel P-P plot
IGAUSS(iGauss-options)	specifies inverse Gaussian P-P plot
LOGNORMAL(lognormal-options)	specifies lognormal P-P plot
NORMAL(normal-options)	specifies normal P-P plot
PARETO(Pareto-options)	specifies generalized Pareto P-P plot
POWER(power-options)	specifies power function P-P plot
RAYLEIGH(Rayleigh-options)	specifies Rayleigh 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 $\mu$ and $\sigma$ for the normal distribution, and the COLOR= normal-option specifies the color for the line.
