Returns the population covariance of two variables, ml.data.frame fields.
1 | cov.pop(x, y)
|
x |
a ml.data.frame field. |
y |
a ml.data.frame field |
The function eliminates all pairs for which either the first element or the second element is empty. After the elimination, if the length of the input is 0, the function returns the empty sequence.
