/math-82cf10eee6fa9feaacb137cff874409c.png?v=0 "b = \frac{\sum{(x-\bar{x})(y-\bar{y})}}{\sum{(x-\bar{x})^2}}")
where /math-6fbdf291cda891b99cf211417ad1df18.png?v=0 "\bar{x}")
and /math-bacfc7141fdfd692244b6c50891d1f7b.png?v=0 "\bar{y}")
are the means of x and y.
Syntax
double Slope(vector vx, vector vy)
Parameters
vx
- Input vector for independent variable.
vy
- Input vector for dependent variable.
Return
Return the the slope of the linear regression of the given curve.
Example
newbook; col(A) = data(1,5); col(B) = uniform(5); Slope(col(A),col(B)) = ;
