Curve Fitting Improvements
General
Improve Fitting Graph and Residual Graphs
| Arrange multiple residual plots in one graph with multiple layers |
|---|
 |
| Support Normal Probability Plot of Residuals |
 |
Linear Fit
Auto-detect Outliers in Linear Fit Tool
In Linear Fit tool, outliers can be auto-detected and output
More Results supports in Apparent Fit
- Enable Standardized Residual, Studentized and Studentized Deleted Residual for Apparent Fit
- Support outlier result for Apparent Fit
Nonlinear Curve Fitting
Keep Zoom Status on Fit Curve tab When Doing Interactions
When doing a fit from graph, user can first uncheck Show Preview on Source Graph checkbox on Fitted Curves page. Then Fit Curve tab will show a preview fitted curve. Zoom In, Zoom Out and Rescale buttons are added on the tab to see more details during iteration or fitting.
