| Resumen |
It is known that Pearson’s correlation coefficient r is equal to the cosine of the angle between the vectors ⃗x and ⃗y describing the centered data. We use this known fact to show that r describes how closer the corresponding unit vector
⃗ex = ⃗x is to the y-unit vector ⃗ey = ⃗y than to its opposite - |
