Sample Covariance. Given n pairs of observations (x1, y1), (x2, y2), . . . , (xn, yn), sample covariance sxy is a measure of the direction and strength of the linear relationship between X and Y, defined as. 1 Xn. sxy − ̄y) (xi − ̄x)(yi. = n − 1 i 1 = sxy > 0: Positive linear relation; sxy < 0: Negative linear relation. The.
