時間Tue Jan 20 17:29:50 2009
請教一下
如果要檢驗截距的變動
設一個虛擬變數的話
data cost;
infile 'c:\book111.prn';
input year cost labor capita ;
if year>1985 then d1=1; else d1=0;
d1labor=d1*labor;
d1capita=d1*capita;
run;
proc reg data=cost/ ;
model cost=d1 labor capita/ ;
run;
小弟的設法是這樣設的
可是電腦老是跟我說他跑不出來
896 proc reg data=cost/ ;

200
