WebMaximum likelihood is a relatively simple method of constructing an estimator for an un- known parameterµ. It was introduced by R. A. Fisher, a great English mathematical statis … WebThe likelihood function is the joint distribution of these sample values, which we can write by independence. ℓ ( π) = f ( x 1, …, x n; π) = π ∑ i x i ( 1 − π) n − ∑ i x i. We interpret ℓ ( π) as the probability of observing X 1, …, X n as a function of π, and the maximum likelihood estimate (MLE) of π is the value of π ...
