Launch the Fit Curve Platform

To launch the Fit Curve platform, select Analyze > Specialized Modeling > Fit Curve. The launch window is shown in Figure 14.6.

For more information about the options in the Select Columns red triangle menu, see Column Filter Menu in Using JMP.

The Fit Curve platform launch window has the following features:

Y, Response

Specify the Y variable.

X, Regressor

Specify the X variable.


Specify a grouping variable. The fitted model has separate parameters for each level of the grouping variable. This enables you to compare fitted models and estimated parameters across the levels of the grouping variable.

Z, Supplementary

Specify one or more supplementary variables. Supplementary variables are not used in any of the calculations in the Fit Curve platform and including them does not affect the results. Supplementary variables are variables you might want to use in future analyses of the results from Fit Curve. When you specify supplementary variables, they are included in the table that is created by the Make Parameter Table option. In JMP Pro, if you specify one or more supplementary variables and a grouping variable, a Curve DOE Analysis option is made available for the fitted models. See Curve DOE Analysis.


Specify a variable that contains the weights of the observations.


Specify a variable that contains the frequencies of the observations.


Specify a variable to perform a separate analysis for every level of the variable.
