Usage Examples

The examples in this section are based on the following sample graph:

CREATE (:REGR_TEST {x_property: 1 , y_property: 2 })
CREATE (:REGR_TEST {x_property: 2 , y_property: 3 })
CREATE (:REGR_TEST {y_property: 10000 })
CREATE (:REGR_TEST {x_property: 3 , y_property: 6 });

CALL apoc.math.regr('REGR_TEST', 'y_property', 'x_property');
