Details
Syntax	`apoc.math.regr(label, propertyY, propertyX) :: (r2, avgX, avgY, slope)`
Description	Returns the coefficient of determination (R-squared) for the values of propertyY and propertyX in the given label.
Input arguments	Name	Type	Description
	`label`	`STRING`	The label of the nodes to perform the regression on.
	`propertyY`	`STRING`	The name of the y property.
	`propertyX`	`STRING`	The name of the x property.
Return arguments	Name	Type	Description
	`r2`	`FLOAT`	The coefficient of determination.
	`avgX`	`FLOAT`	The average of the x values.
	`avgY`	`FLOAT`	The average of the y values.
	`slope`	`FLOAT`	The calculated slope.

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');
