Breakpoint Regression - Quick Tab
The Quick tab of the Breakpoint Regression dialog box contains the options described here.
| Element Name | Description |
|---|---|
| Variables | Click the Variables button to display the standard variable selection dialog box, in which you select a dependent variable and the independent or predictor variables. |
| Breakpoint | The Breakpoint group box contains two option buttons: Estimated by program and User-defined. |
| Estimated by program | Select the Estimated by program option button for STATISTICA to estimate the breakpoint (starting at the mean for the dependent variable). |
| User-defined | Select the User-defined option button to specify a breakpoint for the regression (in which case, the breakpoint value that you enter in the adjacent box will be treated as a constant in the estimation procedure, rather than as a parameter to be estimated).See also: Nonlinear Estimation - Piecewise Regression. |
