PROC CAPABILITY: Summary of Options

The CAPABILITY Procedure

Summary of Options

The following tables list all options by function. The section Dictionary of Options describes each option in detail.

Distribution Options

You can use the options listed in Table 5.8 to superimpose a fitted theoretical distribution function on your cdf plot.

Table 5.8 Options for Specifying a Theoretical Distribution
Option	Description
BETA(beta-options)	plots two-parameter beta distribution function, parameters $\text{[math]}$ and $\text{[math]}$ assumed known
EXPONENTIAL(exponential-options)	plots one-parameter exponential distribution function, parameter $\text{[math]}$ assumed known
GAMMA(gamma-options)	plots two-parameter gamma distribution function, parameter $\text{[math]}$ assumed known
LOGNORMAL(lognormal-options)	plots two-parameter lognormal distribution function, parameter $\text{[math]}$ assumed known
NORMAL(normal-options)	plots normal distribution function
WEIBULL(Weibull-options)	plots two-parameter Weibull distribution function, parameter $\text{[math]}$ assumed known

Table 5.9 summarizes options that specify distribution parameters and control the display of the theoretical distribution curve. You can specify these options in parentheses after the distribution option. For example, the following statements use the NORMAL option to superimpose a normal distribution:

proc capability;
   cdfplot / normal(mu=10 sigma=0.5 color=red);
run;

The COLOR= option specifies the color for the curve, and the normal-options MU= and SIGMA= specify the parameters $\text{[math]}$ and $\text{[math]}$ for the distribution function. If you do not specify these parameters, maximum likelihood estimates are computed.
