I have created a linear regression model using Proc Reg output my parameters to use in Proc Score and produced the predicted values in my output table. However when I used Proc Score on data (including the data used to build the model) the values for the data I used to build the model are different in Proc Score to the output predicted values in Proc Reg. Can anyone explain this? (EG 7.1) Target P_Reg P_Score 88806 89207.13 89300.56 89051 89286.64 89421.16 89397 89364.52 89541.75 90354 90080.69 90134.00 90984 90552.01 90541.30 91283 90979.03 90948.60
