Return to the original model. We now introduce a Poisson intensity parameter X for every time point and denote the parameter () that gives the canonical exponential family representation as above by θ, . We choose to employ a linear model connecting the time points t with the canonical parameter of the Poisson distribution above, i.e., n other words, we choose a generalized linear model with Poisson distribution and its canonical link function. That also means that conditioned on t,...

Question 3 (5101) Suppose that N ~ Poisson(2), and that X has a conditional distribution that depends on N. There are two possible models for this conditional distribution: • Model M: X|N=n~ N(2*n, 02 = 1) • Model M2: X|N=n~ N(2+n + n2,02 = 1) The only difference between M, and M2 is the conditional mean function - the mean function is linear in M, and quadratic in M2. a If M is true: Find E(X) and V.

On a highway, cars pass according to a Poisson process with rate 5 per minute. Trucks pass according to a Poisson process with rate 3 per minute. The two processes are independent. Let Nc(t) and NT(t) denote the number of cars and trucks that pass in t minutes, respectively. Then N(1)=NC(1)+NT(1) is the number of vehicles that pass in minutes.
