Using this simplification, consider the regression of y_i on x_i1 and x_i2 with no intercept. (a)Use the normal equation from the regression of y_i on x_i1 and x_i2 to derive an expression for the slope coefficents in terms of b1=(Sum y_i* x_i1)/(Sum(x_i1)^2) and b2==(Sum y_i* x_i1)/(Sum(x_i1)^2) the lope coefficient from the two simple regression of y_i on x_i1 and y_i on x_i2. (b)in part (a) you should have terms like =(Sum x_i1* x_i2)/(Sum(x_i1)^2) and =(Sum x_i1* x_i2)/(Sum(x_i2)^2). give an interpretation of these terms. (c)what does would it mean if the terms in part(b) were zero? what would the relationship between the slope coefficients from the long regression in (a) and the term b1 and b2 look like? how would you interpret this case? • Show less Ready to try a high quality writing service?
