Covariance
Summary
The covariance of two random variables measures how they vary together. It is positive when large values of one go with large values of the other, and negative in the opposite case. The node covariance gives the precise definition.
What this node needs for W2
- edge instance_of in: at least two examples (0 of 2)
- edge not_instance_of in: at least one non-example (0 of 1)
- edge specializes both: the more general notions and the special cases (0 of 1)
The writing levels say how complete the text of a node is. They do not measure its truth.
