4. In class on Monday, we will considered two-sided confidence intervals for B given a single...
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...
Need help with stats true or false questions Decide (with short explanations) whether the following statements are true or false a) We consider the model y-Ao +A(z) +E. Let (-0.01, 1.5) be a 95% confidence interval for A In this case, a t-test with significance level 1% rejects the null hypothesis Ho : A-0 against a two sided alternative. b) Complicated models with a lot of parameters are better for prediction then simple models with just a few parameters c)...
