ABayes Is the confidence Region R(a,b) symmetric around the Bayesian estimatorA , as defined earlier? Why or Why not? (a)Yes, because by construction, confidence intervals and hence confidence regions are symmetric around any consistent of the parameter (b)Yes, because our posterior distribution is symmetric and we chose a and b such that (-o0, a) and (b,oo) have an equal 5% Probability. (c)No, because our posterior distribution is not symmetric (it is either skewed to the left or skewed to the...

Bayesian Estimation and Confidence Regions: Concept Questions Σχ.-12 Consider the scenario where we observe n 10 random variable with sum AMAP M. Bayes Compare the values of the Bayes' estimator A0.833 and the maximum a-poster estimator -0.75 calculated earlier. Which of the following statements correctly describes the relative values and provides an accurate justification for it? (a) because this inequality will always hold regardless of the prior or model choice 1 ABaves AMAP (b) A< 1 because this inequality will...
