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.

Figure 13.5: Selecting Plots

Note: Stat 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.
