Question
We would like to fit a linear regression estimate to the dataset D = (2) (N) ,, (x (i) with x"" ER" by minimizing the ordinary least square (OLS) objective function: N M J(w) -E w; X j =1 i=1 Specifically, we solve for each coefficient Wk (1 <k < M) by deriving an aJ (w. =0. What is the expression for each Wk in terms of (a) expression of Wk from the critical point the dataset (v(1) N, yN) and w1, ·', Wk-1, Wk+1, *', WM ? Select one: Wi Wk = i =1 (Xk M Wk = Wk = x) 4=1 Wk = (b) How many coefficients do you need to estimate? When solving for these coef- ficients, how many equations do you have? Select one: N coefficients, M equations M coefficients, N equations M coefficients, M equations N coefficients, N equations
