The method of moments estimator of μ based on Xn is the sample mean Mn = 1 n n ∑ i = 1Xi. E(Mn) = μ so Mn is unbiased for n ∈ N +. var(Mn) = σ2 / n for n ∈ N + so M = (M1, M2, …) is consistent.

Compute the posterior probability given a Bernoulli distributed likelihood

NettetFor example, The binomial distribution can also be used to calculate the likelihood of a specific number of successes occurring in a given number of independent Bernoulli trials with a defined probability of success for each trial. This type of calculation is known as the binomial probability distribution. NettetP ( X = x) = λ x e − λ x! x = 0, 1, 2, …. The parameter λ represents the expected number of goals in the game or the long-run average among all possible such games. The expression x! stands for x factorial, i.e., x! = 1 ∗ 2 ∗ 3 ∗ ⋯ ∗ x. P ( X = x) or P (x) is the probability that X (the random variable representing the unknown ...
