(b) Find the natural log of the likelihood function simplifying as much as possible. Loglikelihood = (c) Take the derivative of the log likelihood function you found in part (b) and make it 0. Solve for the unknown population parameter as a function of some of the summary statistics we know (X¯, or S 2 or whatever applies. ) That is your maximum likelihood estimator (MLE) of the unknown parameter. PART C ONLY Problem 2. Consider a random sample of...

R codeing simulation For n = 20, simulate a random sample of size n from N(µ, 2 2 ), where µ = 1. Note that we just use µ = 1 to generate the random sample. In the problem below, µ is an unknown parameter. Plot in different figures: (a) the likelihood function of µ, (b) the log likelihood function of µ. Mark in both plots the maximum likelihood estimate of µ from the generated random sample (2) For n-20,...
