Note: The input table should not contain missing values. You can use the Missing Value node to replace them.

Options

Geometry column: Select the geometry column to use.
Dependent variable: The column containing the dependent variable to use for the calculation of Multiscale Geographically Weighted Regression.
Independent variables: The columns containing the independent variables to use for the calculation of Multiscale Geographically Weighted Regression.
Search method: Bw search method: ‘golden’, ‘interval’. Golden Search— Determines either the number of neighbors or distance band for each explanatory variable using the Golden Search algorithm. This method searches multiple combinations of values for each explanatory variable between a specified minimum and maximum value. Intervals— Determines the number of neighbors or distance band for each explanatory variable by incrementing the number of neighbors or distance band from a minimum value.
Bandwith min: Min value used in bandwidth search
Kernel: type of kernel function used to weight observations; available options: ‘gaussian’ ‘bisquare’ ‘exponential’
