Conditional variance

Summary

The conditional variance of XX given some information measures the spread of XX around its conditional expectation. It is itself a random variable. The node conditional variance gives the precise definition.

What this node needs for W1
  • an inventory row: the row of the inventory that the node accounts for (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
