小弟在编写out-of-sample regression 模型进行回归时，遇见问题：

拟合优度过高， 回归结果为：

小弟想请教到底什么地方出现问题，原始程序为：

%let model1=totaltransactionvalue1 priorcap1 totalcommonequity1 gdp1 beta1 percentsought1;

ods pdf file='C:\Users\feng\Desktop\haw project\sas assi\outsample2.pdf' startpage=yes uniform;

%macro out_loop;

%do i=2006 %to 2010;

%v(start_est=1989, end_est=&&i., start_forecast=&&i., end_forecast=&&i.+1);

%end;

%mend outer_loop;

%macro v(start_est= , end_est= , start_forecast= , end_forecast= );

data X;

set a;

if year gt &end_est then xcontrolpremium1=.;

if &start_est<= year <=&end_est then xcontrolpremium1=controlpremium1;

if &start_est<= year <=&end_forecast;

run;

proc reg data=x;

model controlpremium1=&model1;

output out=predicted_out;

title 'regression model';

run;

%mend v;

%out_loop;
