Measured vs. Predicted (<method>)

Model menu > Error (<method> = Leave One Out or Test Data or Training Data) > Measured vs. Predicted

Note
The description of this window refers to the error that is based on the Leave-One-Out method, but it applies analogously to the errors based on training or test data.

In each plot, the model output is displayed on the X-axis and the measuring points are displayed on the Y-axis. A perfect match between the two would result in a "pearl necklace" (y = x) on the line drawn in blue. The further the points are removed from the blue line, the greater the difference between measurement and model output. This allows visually determining the model quality.

It also allows recognizing outliers, i.e. points that are located far away from the blue line. Possible reasons for their occurrence can be measurement errors or even a still insufficient model quality.

In the header of each graphic, the model type as well as the RMSE and the R² value are displayed. These are two standard variables for assessing the quality of models (see the ASCMO-STATIC Help).

The Measured vs. Predicted (<method>) window contains the following elements:

File

• New

  Note
  Unavailable in some scatter plot windows.

  Opens the Select Axes window where you can select axes pairs to be plotted in an additional window.

• Export All Data

  Exports all data points into an Excel (*.xls, *.xlsx), CSV (*.csv), MDF3 (*.dat) or MDF4 (*.mf4) file.

• Export Intersection of Selected Data

  Exports the data points in the overlap area of all rectangles into an Excel (*.xls, *.xlsx), CSV (*.csv), MDF3 (*.dat) or MDF4 (*.mf4) file. These data points appear as red dots in the scatter plot.

  

  If there is no area where all rectangles overlap, or if the overlap area of all rectangles is empty, there are no data points that can be exported.

• Export Union of Selected Data

  Exports the data points in all rectangles, i.e. all colored dots in the scatter plot, into an Excel (*.xls, *.xlsx), CSV (*.csv), MDF3 (*.dat) or MDF4 (*.mf4) file.

  This export function works for overlapping and non-overlapping rectangles.

• Close

  Closes the window.

Extras

• Remove All Rectangles/Lassos

  All rectangles or lassos in the scatter plots are removed again.

• Detect Outlier

  Identifies all outliers determined according to the defined criteria and marks them with a red circle.

• Unmark All

  All marked points are unmarked.

• Set Outlier Threshold

  Note
  Only available if the Advanced Settings are enabled.

  Shows a slider and an editing field in the plot window.

  

  Points that meet both of the following conditions are identified as outliers:

  • Outlier Threshold

    The adjustable value ranges from 10^-14 to 1 (level of significance).

  • Sigma

    Value of standard deviation

• Delete Marked Points and Retrain

  Deletes all points marked in any of the plots, saves the dataset and starts a new model training.

• Show Inputs

  Opens the Inputs for Measured vs. Predicted (<method>) window.

View

• Plot Settings

  Opens the Edit Axes window where you can set the minimal size of the plots in pixel. If you change the size and click OK or Apply, each scatter plot smaller than the new values is adapted automatically.

  Note
  The information in the Edit Axes window will be saved in ASCMO-STATIC and used in all scatter plots.

• Prepare Print

  Opens the Prepare Print Options window where you can adjust the look of the plot area. The settings are reset when you close the plot window.

  

• Save as Bitmap

  This allows the content of the window to be saved in a series of graphic formats.

• Copy to Clipboard

  Copies the window content to the clipboard.

• Update

  Updates the plots in the window.

Help

• User Guide: Opens the PDF User Guide.

• Online Help: Opens the online help (F1).
