Is it possible to calculate an exact/approximate expectation over an argmax function of a random variable?
given a non-increasing vector $b\in R^n$ I would like to calculate the expected argmax of the function f(b) = i*b_i.
More clear and mathematical meaning.
It's worth mentioning that I assume that the vector $b$ is drawn from some known distribution…

Find unbiased estimator for (1+λ)e−λ in a poisson distribution
My Attempt:
I tried using the MLE of λ which I find the sample mean. Then using the invariance property and it follows that (1+X¯)e^−X¯will be the MLE of (1+λ)e^−λ but I'm not sure if it is also unbiased.
