Spatial Error Model

ML estimation of the spatial error model with all results and diagnostics. More details can be found at Luc Anselin. Spatial Econometrics: Methods and Models. Kluwer, Dordrecht, 1988.

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.
ID column: Select the column which contains for each observation in the input data a unique ID, it should be an integer column. The IDs must match with the values of the Spatial Weights node ID column. If 'none' is selected, the IDs will be automatically generated from 0 to the number of rows flowing the order of the first input table.
Dependent variable: The column containing the dependent variable to use for the calculation of the spatial ML_Error model.
Independent variables: The columns containing the independent variables to use for the calculation of the spatial ML_Error model.
Method: if ‘full’, brute force calculation (full matrix expressions) if ‘ord’, Ord eigenvalue method if ‘LU’, LU sparse matrix decomposition

Advanced Settings

Advanced Setting

Epsilon: tolerance criterion in mimimize_scalar function and inverse_product
