Question:

(Bayesian) Suppose that X is Poisson(λ + 1), and the prior distribution of λ is binomial(2,1/3).

(a) Find the Bayesian estimate of λ for mean square loss based on the single observation X, if X = 1.

(b) Find the Bayesian estimate of λ for mean square loss based on the single observation X, if X = 2

Hints:

Because of its prior distribution, λ can take only three values, 0,1,2.

Don’t expect its posterior distribution to be any distribution we have seen before;

You will have to compute (numerically) the posterior probabilities of the three possible values.

Determine the Maximum Likelihood Estimator for; 1. λ for the Poisson distribution. 2. θ for the Exponential distribution. Caveat: These are examples of distributions for which the MLE can be found analytically in terms of the data x1, . . . , xn and so no advanced computational methods are required and also in each assume a random sample of size n, x1, x2, . . . , xn

The number of imperfections in an object has a Poisson distribution with a mean λ = 8.5. If the number of imperfections is 4 or less, the object is called "top quality." If the number of imperfections is between 5 and 8 inclusive, the object is called "good quality." If the number of imperfections is between 9 and 12 inclusive, the object is called "normal quality." If the number of imperfections is 13 or more, the object is called "bad...

For the Poisson Distribution a. Is λ×T a parameter of position, scale, shape or a combination? Explain. b. We can treat “λ×T” as a single parameter, but they actually represent two parameters: λ and T. Say you stand by the side of the road and count the number of cars that pass by you in one minute. After repeating this process 10 times you find the average number of cars that pass in 10 minutes. In this case, what is...

Both X and S2 are unbiased for the Poisson λ. Which is better? Use the following steps to answer this question. a) Generate 200000 random numbers from the Poisson(λ = 2) distribution and arrange them in a matrix with 20 rows. Thus you have 10000 samples of size 20. b) Compute the 10000 sample means and sample variances and store them in objects means and vars, respectively. c) Compute the average of the 10000 sample means and the average of...
