2. Find the MLE for the discrete RV given in problem 5 of HW2 (using the particular data indicated in that problem). Then, explain why your answer for the MLE cannot be surprising (like it was on HW2). You should also draw a picture of the likelihood and log-likelihood (on the same axes) in Desmos and copy your Desmos inputs and picture into your solutions. Thinlk carefully about the domain of this graph x=1 5. Suppose a discrete RV is...

Instructions: For each of the following distributions, compute the maximum likelihood estimator based on n i.d. observations X····, Xn and the Fisher information, if defined. If it is not, enter DNE in each applicable input box. which means that each X1 has density exp (-( 1)2 202 Hint: Keep in mind that we consider σ2 as the parameter, not σ . You may want to write τ-σ2 in your computation. (Enter barx_n for the sample average Xn and bar(X_n 2)...
