SAGA.statistics_regression.1: Multiple Regression Analysis (Points and Predictor Grids)

Linear regression analysis of point attributes with multiple grids. Details of the regression/correlation analysis will be saved to a table. The regression function is used to create a new grid with regression based values. The multiple regression analysis uses a forward selection procedure.
