Distribution Analysis: Descriptive Statistics

The Plots Tab

You can use the Plots tab (Figure 13.5) to create a histogram and a box plot of the chosen variable.

The histogram can include a kernel density estimate. You can determine the bandwidth for the kernel density method by selecting an option from the Selection method list. The options are as follows:

MISE
specifies that the kernel bandwidth is chosen to minimize an approximate mean integrated square error.
Sheather-Jones
specifies that the kernel bandwidth is chosen by a plug-in formula of Sheather and Jones.
Manual
sets the kernel bandwidth to the value of the Bandwidth field.

Note: SAS/IML Studio adds a kernel density estimate to an existing histogram when both of the following conditions are satisfied:
