Question: Given data points (x i , y i ), i = 1, 2,...., n and y i = b 0 + b 1 x i

Given data points (xi, yi), i = 1, 2,...., n and yi = b0 + b1xi + ci.

Let RRS( b0 , b1) = i=1n (yi - b0 - b1xi)2

x =(1/n) i=1n xi

y =(1/n)i=1n yi

Show that

b^0 = y - b^1x

b^1 = ( i=1n ( xi - x )( yi - y )) / ( i=1n ( xi - x )2 )
