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=colorspecifies color of normal curve
FILLfills area under normal curve
L=linetypespecifies line type of normal curve
MU=valuespecifies mean \mu for fitted normal curve
SIGMA=valuespecifies standard deviation \sigma for fitted normal curve
W=nspecifies 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);

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 | MISEspecifies standardized bandwidth parameter c for kernel density estimate
COLOR=colorspecifies color of the kernel density curve
FILLfills area under kernel density curve
K=keywordspecifies NORMAL, TRIANGULAR, or QUADRATIC kernel
L=linetypespecifies line type used for kernel density curve
W=nspecifies line width for kernel density curve
