Summary of Options

COMPHISTOGRAM Statement

Summary of Options

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

Normal Curve Options

Table 3.1 summarizes options that specify features of fitted normal distributions requested with the NORMAL option. Specify these options in parentheses after the NORMAL option.

Table 3.1: Normal-Options

COLOR=color	specifies color of normal curve
FILL	fills area under normal curve
L=linetype	specifies line type of normal curve
MU=value	specifies mean $\mu$ for fitted normal curve
SIGMA=value	specifies standard deviation $\sigma$ for fitted normal curve
W=n	specifies width of normal curve

For example, the following statements use the NORMAL option to fit a normal curve in each cell of the comparative histogram:

proc capability;
   comphistogram / class = machine
                   normal(color=red l=2);
run;

The COLOR= normal-option draws the curve in red, and the L= normal-option specifies a line style of 2 (a dashed line) for the curve. In this example, maximum likelihood estimates are computed for the normal parameters $\mu$ and $\sigma$ for each cell since these parameters are not specified.

Kernel Options

You can specify the options listed in Table 3.2 in parentheses after the keyword KERNEL to control features of kernel density estimates requested with the KERNEL option.

Table 3.2: Kernel Options

C=value-list \| MISE	specifies standardized bandwidth parameter c for kernel density estimate
COLOR=color	specifies color of the kernel density curve
FILL	fills area under kernel density curve
K=keyword	specifies NORMAL, TRIANGULAR, or QUADRATIC kernel
L=linetype	specifies line type used for kernel density curve
W=n	specifies line width for kernel density curve
