We generate a random variable Y ∼ Exp(1). Given Y = y, then we generate another exponential random variable X whose rate parameter is y.
(a) Find the joint density of (X, Y )
(b) Suppose we observe X = x but not the value of Y . What is now the conditional density of Y ?
We generate a random variable Y ∼ Exp(1). Given Y = y, then we generate another...
