Chapter , Problem 16(choose chapter or problem)
Consider fitting the curve \(y=\beta_0 x+\beta_1 x^2\) to points \(\left(x_i, y_i\right)\), where \(i=1, \ldots, n\).
a. Use the matrix formalism to find expressions for the least squares estimates of \(\beta_0\) and \(\beta_1\).
b. Find an expression for the covariance matrix of the estimates.
