Marginal distributions of the nodes when conditioning on TR=1.
although the frequency of treated crops is greater, the loss is greater than for
the cases where treatment was not applied.
For the moment, we based our inference just on the marginal distributions
of the nodes conditional on a single node. In fact, many other configurations
are possible, such as fixing several nodes and considering simultaneously the
marginal or joint distributions ...
