PROBPLOT Statement |
The following tables list the PROBPLOT statement options by function. For complete descriptions, see the "Dictionary of Options" section.
BETA(beta-options) | specifies beta probability plot for shape parameters , specified with mandatory ALPHA= and BETA= beta-options |
EXPONENTIAL(exponential-options) | specifies exponential probability plot |
GAMMA(gamma-options) | specifies gamma probability plot for shape parameter specified with mandatory ALPHA= gamma-option |
LOGNORMAL(lognormal-options) | specifies lognormal probability plot for shape parameter specified with mandatory SIGMA= lognormal-option |
NORMAL(normal-options) | specifies normal probability plot |
WEIBULL(Weibull-options) | specifies three-parameter Weibull probability plot for shape parameter c specified with mandatory C= Weibull-option |
WEIBULL2(Weibull2-options) | specifies two-parameter Weibull probability plot |
Table 9.2 through Table 9.9 summarize options that specify distribution parameters and control the display of a 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 probability plot with a distribution reference line:
proc capability data=measures; probplot length / normal(mu=10 sigma=0.3 color=red); run;
The MU= and SIGMA= normal-options display a distribution reference line that corresponds to the normal distribution with mean and standard deviation , and the COLOR= normal-option specifies the color for the line.
