ToBivariate

tobivariate($x,$y)

Combines two separate data parameters into a bivariate parameter. The number of data points in $x and $y must match.

If $x=data(1,3,5,6,7,7,9)

and

$y=data(7,6,6,4,3,2,2)

$b=toBivariate($x,$y)

=> $b = (1,7) (3,6) (5,6) (6,4) (7,3) (7,2) (9,2)

You can calculate correlation coefficient and regression lines on bivariate parameters using regr(), regslope() and regintercept().
