Consider the following Bayesian network and answer the following questions. For justification you must use the d-separation algorithm and specify which canonical case of conditional independence is in effect. For example, if the question is: Are S and T conditionally independent given R? Justify. Standard Answer: They are conditionally independent because S & T are in tail- to-tail connection (case 2) and R is in the path from S to T a) Are P and Q conditionally independent given S? Justify b) Are P and Q conditionally independent given V? Justify. c) Are P and W conditionally independent given R? Justify. d) Are S and T conditionally independent given P? Justify. e) Are U and W conditionally independent given V? Justify
