WebIn Poisson distribution, the mean of the distribution is represented by λ and e is constant, which is approximately equal to 2.71828. Then, the Poisson probability is: P (x, λ ) = (e– λ λx)/x! In Poisson distribution, the mean is represented as E (X) = λ. For a Poisson Distribution, the mean and the variance are equal. It means that E (X ... Web1.3 - Unbiased Estimation. On the previous page, we showed that if X i are Bernoulli random variables with parameter p, then: p ^ = 1 n ∑ i = 1 n X i. is the maximum likelihood estimator of p. And, if X i are normally distributed random variables with mean μ and variance σ 2, then: μ ^ = ∑ X i n = X ¯ and σ ^ 2 = ∑ ( X i − X ¯) 2 n.
