Show Prediction Expression

In the Fit Least Squares report, the Show Prediction Expression option shows the equation used to predict the response. Figure 3.20 shows an example for the Drug.jmp sample data table. This expression is given as a typical JMP formula. For example, to predict the response for someone on Drug a with x = 10, you would calculate, with some rounding: –2.696 - 1.185 + 0.987(10) = 5.99.

Tip: To specify the number of digits in the prediction formula, go to File > Preferences > Tables and change the Default Field Width value.
