20. develop a method for estimating the parameter of the Poisson distribution by a confidence level
Consider the following method of estimating λ for a Poisson distribution. Observe that p0 = P(X = 0) = e(-λ) Letting Y denote the number of zeros from an i.i.d. sample of size n, λ might be estimated by λ˜ = − log(Y/n) Use the method of propagation of error to obtain approximate expressions for the variance and the bias of this estimate. Compare the variance of this estimate to the variance of the mle, computing relative efficiencies for various...
A. What is the probability of obtaining exactly 6 events for a Poisson distribution with parameter u=4.0? B. What is the probability of obtaining at least 6 events for a Poisson distribution with parameter u=4.0?
a. What is the maximum likelihood estimator for the parameter 2 of the poisson distribution for a sample of n poisson random variables?
*******Please help!!!******* Thank you so much, any help is accepted 5.20 R : Consider a Poisson distribution with parameter λ=3 conditioned to be nonzero. Implement an MCMC algorithm to simulate from this distribution, using a proposal distribution that is geometric with parameter p 1/3. Use your simulation to estimate the mean and variance. 5.20 R : Consider a Poisson distribution with parameter λ=3 conditioned to be nonzero.
