Figure 8.3 Fit Y by X Launch Window

The word Logistic appears above the image, to indicate that you are performing a logistic analysis.

Note: You can also launch a logistic analysis from the JMP Starter window. Select View > JMP Starter > Basic > Logistic.

When the response is binary and has a nominal modeling type, a Target Level menu appears in the launch window. Use this menu to specify the level of the response whose probability you want to model.

For more information about the Fit Y by X launch window, see Introduction to Fit Y by X. For more information about the options in the Select Columns red triangle menu, see Column Filter Menu in Using JMP.

Your data can consist of unsummarized or summarized data:

Unsummarized data

There is one row for each observation containing its X value and its Y value.

Summarized data

Each row represents a set of observations with common X and Y values. The data table must contain a column that gives the counts for each row. Enter this column as Freq in the launch window.
