WebApr 17, 2024 · (i) Find the maximum likelihood estimator of θ My solution: θ = n ∑ i = 1 n x i Therefore, E ( θ ^) = 1 θ (ii) Hence show that the maximum likelihood estimator of ψ = ( 1 − θ) θ is the sample mean ( X ¯). Try as I might, I can't re-arrange the answer to question 1 into the form shown in question 2. Please may someone help me? statistics WebMay 20, 2013 · p = n (∑n 1xi) So, the maximum likelihood estimator of P is: P = n (∑n 1Xi) = 1 X. This agrees with the intuition because, in n observations of a geometric random variable, there are n successes in the ∑n 1 Xi trials. Thus the estimate of p is the number of successes divided by the total number of trials. More examples: Binomial and ...
