in #14 there is something different. betewwn the predict variable when Iam using the code predict predict ,xb and what Iam did in the equation to check if its correct or not
so for example in 2010 the coefficient of varx = 1.039071 and coefficient of varY = -0.8751376 and the constant 0.645611 and the equation 0.645611+1.039071*C2134+(-0.8751376*E2134) =1.1754 and when Iam using this code you send it to me the predict = 1.6745 . could you please that. if you dont mind and thank you again for your help
