Regression layer accuracy report

Estimates map accuracy.We use the formulas as described in Scikit-Learn Regression metrics user guide. Observed and predicted target variables are matched by name.

Usage:

1. Start the algorithm from the Processing Toolbox panel.

2. Select a regression layer and an observed countinous-valued layer, then click run.

   

3. The output accuracy report will automatically be opened in your web browser.

Parameters

Regression layer [raster]

A regression layer that is to be assessed.

Observed continuous-valued layer [layer]

A continuous-valued layer representing a (ground truth) observation sample.

Open output report in webbrowser after running algorithm [boolean]

Whether to open the output report in the web browser.

Default: True

Outputs

Output report [fileDestination]

Report file destination.
