HISTOGRAM Statement

Summary of Options

The following tables list the HISTOGRAM statement options by function. For detailed descriptions, see "Dictionary of Options".

Parametric Density Estimation Options

Table 4.1 lists options that display a parametric density estimate on the histogram.

Table 4.1: Parametric Distribution Options

BETA(beta-options)	fits beta distribution with threshold parameter $\theta$ ,scale parameter $\sigma$ ,and shape parameters $\alpha$ and $\beta$
EXPONENTIAL(exponential-options)	fits exponential distribution with threshold parameter $\theta$ and scale parameter $\sigma$
GAMMA(gamma-options)	fits gamma distribution with threshold parameter $\theta$ ,scale parameter $\sigma$ ,and shape parameter $\alpha$
LOGNORMAL(lognormal-options)	fits lognormal distribution with threshold parameter $\theta$ ,scale parameter $\zeta$ ,and shape parameter $\sigma$

WEIBULL(Weibull-options)	fits Weibull distribution with threshold parameter $\theta$ ,scale parameter $\sigma$ ,and shape parameter c

Table 4.2 through Table 4.10 list options that specify parameters for fitted parametric distributions and that control the display of fitted curves. Specify these options in parentheses after the distribution keyword. For example, the following statements fit a normal curve with the keyword NORMAL:

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

The COLOR= normal-option draws the curve in red, and the MU= and SIGMA= normal-options specify the parameters $\mu=10$ and $\sigma=0.5$ for the curve. Note that the sample mean and sample standard deviation are used to estimate $\mu$ and $\sigma$ , respectively, when the MU= and SIGMA= options are not specified.
