Question

I really need the answers to these two small questions. I post several times but no one answer. If you can answer, I will even pay you. Please state your paypal number if you answer it. Thank you!

4. Suppose that (Xi,K), , (XN,Yv) denotes a random sample. Let Si-a+ bXi, T, e+dy, where a, b, c and d are constants. Let X-., Σ Xi, and σ Σ (Xi-X)2, with the analogous expressions for y, ST. Let ởXY-NT Σ(Xi-X)(y-y), and let PXY-ƠXY/(σχσΥ), with the analogous expressions for S, T (e) Let Bo BX be the best linear projection of Y on X. Similarly let omS be the best linear projection of T on S. How do 7o and n relate to Bo and B1? (f) Let ^o and ^i be the OLS estim ators of 70 and i . and ^i relate to 30 How do Yo and Bi , the OLS estimators of ß0 and ß?
