4.1. Consider the linear regression model Yi = = a + Bxi + €i, i = 1,..., n, ‚ €ñ are random variables with zero mean and independent • 9 in which €1,. of (x₁,...,xn). (a) Suppose the e; are independent normal and have common variance ♂². Find the maximum likelihood estimates of a, ß, and o². (b) Suppose (€₁,·.·‚¤n)à has a multivariate normal distribution with covariance matrix o²V, where V is a known correlation matrix and o is an unknown parameter. Find the maximum likelihood estimates of a, ß, and o².
