CDFPLOT Statement: 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 5.9 to superimpose a fitted theoretical distribution function on your cdf plot.

Table 5.9 Options for Specifying a Theoretical Distribution
Option	Description
BETA(beta-options)	plots beta distribution with threshold parameter $\text{[math]}$ , scale parameter $\text{[math]}$ , and shape parameters $\text{[math]}$ and $\text{[math]}$
EXPONENTIAL(exponential-options)	plots exponential distribution with threshold parameter $\text{[math]}$ and scale parameter $\text{[math]}$
GAMMA(gamma-options)	plots gamma distribution with threshold parameter $\text{[math]}$ , scale parameter $\text{[math]}$ , and shape parameter $\text{[math]}$
GUMBEL(Gumbel-options)	plots Gumbel distribution with location parameter $\text{[math]}$ and scale parameter $\text{[math]}$
IGAUSS(iGauss-options)	plots inverse Gaussian distribution with mean $\text{[math]}$ and shape parameter $\text{[math]}$
LOGNORMAL(lognormal-options)	plots lognormal distribution with threshold parameter $\text{[math]}$ , scale parameter $\text{[math]}$ , and shape parameter $\text{[math]}$ ,
NORMAL(normal-options)	plots normal distribution with mean $\text{[math]}$ and standard deviation $\text{[math]}$
PARETO(Pareto-options)	plots generalized Pareto distribution with threshold parameter $\text{[math]}$ , scale parameter $\text{[math]}$ , and shape parameter $\text{[math]}$
POWER(power-options)	plots power function distribution with threshold parameter $\text{[math]}$ , scale parameter $\text{[math]}$ , and shape parameter $\text{[math]}$
RAYLEIGH(Rayleigh-options)	plots Rayleigh distribution with threshold parameter $\text{[math]}$ and scale parameter $\text{[math]}$
WEIBULL(Weibull-options)	plots Weibull distribution function with threshold parameter $\text{[math]}$ , scale parameter $\text{[math]}$ , and shape parameter $\text{[math]}$

Table 5.10 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.
