<element name="DESCRIPTION" text="This algorithm performs a regression analysis, studying the relation between two quantitative variables. The dependent variable is introduced using a points layer, while the independent one is introduced using a raster layer. The algorithm analyzes the relation between them and generates a new raster layer with values of the dependent variable, based on the values of the independent one" description="Description" type="0"> |
