- Covariance[ <List 1 of Numbers>, <List 2 of Numbers> ]
- Calculates the covariance between the elements of the specified lists.
- Example:
Covariance[{1, 2, 3}, {1, 3, 7}]yields 2, the covariance of {1, 2, 3} and {1, 3, 7}.
- Covariance[ <List of Points> ]
- Calculates the covariance between the x and y coordinates of the specified points.
- Example:
Covariance[{(1, 1), (2, 3), (3, 7)}]yields 2, the covariance of {1, 2, 3} and {1, 3, 7}.
