Webb1.3 - 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.
