Distribution Analysis: Descriptive Statistics |
Plots Tab |
You can use the Plots tab to create a histogram and a box plot of the chosen variable. (See Figure 13.5.)
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:
specifies that the kernel bandwidth is chosen to minimize an approximate mean integrated square error.
specifies that the kernel bandwidth is chosen by a plug-in formula of Sheather and Jones (Jones, Marron, and Sheather; 1996).
sets the kernel bandwidth to the value of the Bandwidth box.
Note:SAS/IML Studio adds a kernel density estimate to an existing histogram when both of the following conditions are satisfied:
The histogram is the active window when you select the analysis.
The histogram variable and the analysis variable are the same.
