Consider the multiple regression model y = xβ + subject to a set of linear constraints of the form cβ = γ, where c is m × (k + 1) matrix. the gauss-markov conditions hold and also ∼ n(0, σ2 i). are the quadratic expressions y0 (i − h)y and y0 (h − h1)y independent? (h and h1 are the hat matrices of the full and reduced model respectively.)

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
