Challenge Problems
Push your limits with challenges.
Question 1
Consider a Bayesian network represented as A → B ← C, D → A. If B is conditioned but D is not, determine the independence of A and C. Justify your reasoning.
💡 Hint: Analyze the paths through the collider's definition.
Question 2
Construct a Bayesian network diagram with four variables that demonstrate both blocked and unblocked paths. Explain your findings regarding independence.
💡 Hint: Diagram it to clarify the paths!
