We know that Γ ( r, λ) = 1 Γ ( r) λ r x r − 1 e − λ x if x ≥ 0 . In this case the likelihood function L is. By apllying the logaritmic function to L we semplificate the problem so. and now we must find the point of max of l o g L, so ∂ L ∂ λ = − T + n r λ = 0 which have as solution λ ^ = n r T.

WebAnd, the last equality just uses the shorthand mathematical notation of a product of indexed terms. Now, in light of the basic idea of maximum likelihood estimation, one reasonable way to proceed is to treat the " likelihood function " \ (L (\theta)\) as a function of \ (\theta\), and find the value of \ (\theta\) that maximizes it.
