| ExportPLSCalibration | Exports a PLS calibration model from the specified table. |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetAnalysis | Gets the worksheet analysis stored in the specified model table. |
| GetAvailablePLSCalibrationTables | Gets the available tables that contain PLS calibration models. |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |

| PCAOnColumns | Starts a principal component analysis using the selected worksheet columns. |
| PCAOnRows | Starts a principal component analysis using the selected worksheet rows. |
| PlotCrossPredictedVersusActualY(DataTable) | Plots the cross prediction values of all y components invidually in a graph (without allowing a Gui to catch some errors). |
