please show me procedures,thanks Suppose Yi = beta xi + ei. In this equation X is non-random. beta is a parameter (unknown), and epsilon ~ N(0,singma). Find the mean of Y. Find the variance of V. What distribution does Y follow? Write down the likelihood function based on n observations of Y and x. Find the maximum likelihood estimate of beta. Denote it with beta Show that the estimate of part (e) Ls unbiased estimator of beta Find the variance of this estimate Solution http://www.stat.yale.edu/Courses/1997-98/101/linreg.htm http://onlinestatbook.com/2/regression/intro.html.
