Likelihood. Let X,,..., X, be an i.i.d. sample from a distribution with density function f(x, Ø) = {eif x > 0, if x <0 (2x Tif x >0 f(x, 0) = {0 where 0 > 0 is an unknown parameter. 1. Use method of maximum likelihood to find the estimator for 0. 2. Apply this formula to estimate 0 from the sample (0.5, 0.5, 1).

To find the Maximum Likelihood Estimator, the professor require us to follow and note 4 steps: 1. find L(θ) = product of all the f(XI, θ) 2. take ln(L(θ)) 3. take d/dθ of ln(L(θ)) and set the derivative to 0 4. solve for θ I did: 1) P(X > k) = 1-P(x <= k) = 1-integral of f(k) from 0 to k 2) find the function in terms of θ But I'm not sure what to do with the θ...
