Curve Fitting Improvements

General

Improve Fitting Graph and Residual Graphs 

ORG-10263

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

ORG-10263

In Linear Fit tool, outliers can be auto-detected and output

     

More Results supports in Apparent Fit

ORG-11852

  • 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

ORG-10303

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.
