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:
Start the algorithm from the Processing Toolbox panel.
Select a regression layer and an observed countinous-valued layer, then click run.
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.
