Question

We refer again to the pair of continuous variables X,Y of

f_X,Y(x,y) = l²exp[-lx] for 0 < y < x < ∞ for some parameter l > 0.

Consider the transformation U = X – Y and V = Y.

Determine the joint pdf of U an V using the Jacobian of the transformation, the support of U and V, etc. Do not forget the support.

Are U and V independent? What are their marginal probability density functions and parameters?

They are gamma (U) and exponential (V)

Definition Definition Probability of occurrence of a continuous random variable within a specified range. When the value of a random variable, Y, is evaluated at a point Y=y, then the probability distribution function gives the probability that Y will take a value less than or equal to y. The probability distribution function formula for random Variable Y following the normal distribution is: F(y) = P (Y ≤ y) The value of probability distribution function for random variable lies between 0 and 1.
