The states of the parent affect the noisy node states in increasing order.
In this mode, the first state of the parent variable has no effect, then each subsequent state has increasing causal influence of the noisy node states.
The states of the parent affect the noisy node states in decreasing order.
In this mode, the last state of the parent variable has no effect, and previous states have increasing causal influence over the noisy node states.
Determines the order in which the states of a parent of a noisy node increasingly affect the noisy states.
