CDFPLOT Statement |
The following tables list all options by function. The "Dictionary of Options" describes each option in detail.
BETA(beta-options) | plots two-parameter beta distribution function, parameters and assumed known |
EXPONENTIAL(exponential-options) | plots one-parameter exponential distribution function, parameter assumed known |
GAMMA(gamma-options) | plots two-parameter gamma distribution function, parameter assumed known |
LOGNORMAL(lognormal-options) | plots two-parameter lognormal distribution function, parameter assumed known |
NORMAL(normal-options) | plots normal distribution function |
WEIBULL(Weibull-options) | plots two-parameter Weibull distribution function, parameter assumed known |
You can specify options in parentheses after each distribution option to control features of the theoretical distribution function. 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 and for the distribution function. If you do not specify these parameters, maximum likelihood estimates are computed. Table 2.2: Options Used with All Distribution Options
