如果是数据，手动输入，代码求解即可

如果是带有格式的数据，起码要把年份按行填满，SAS以行为观测导入

如果第四季度存在，在EG的时间序列数据准备中设置直接选按季度

如果不存在，时间序列是无法进行的，需要在EG中的时间序列数据准备中做插值，插值方法见我发的另一篇回复。

***generating a random numbers to create a data set ;
data a(keep=vars); 
 do j=1 to 18;
 vars=int(abs(rannor(j)*100));
 output;
 end;
run;
%macro one(yn=2,qr=3);***year come from 1999 to 2000;***set quarter 3;
%do i=1 %to 3;***read in three variables;
data b&i;
 year=1998;
 onum=(&i-1)*6;
 do m=1 to &yn;***control the year;
 year=year+m;
 do n=1 to &qr;***control the quarter;
 on=onum+n;***control the point number;
 quarter=n;
 set a point=on;***control the observations numbers; 
 var&i=vars; 
 output; 
 end;
 onum=on; 
 end;
 stop;
run;
proc sort;
 by year quarter;

%end;
%mend;
%one
data c(drop= m onum n vars);
 merge b1 b2 b3;
 by year quarter;
run;
proc print data=a;
 title 'The Raw Data Set';
run;
proc print data=c;
 title 'The Objective Data Set';
run;

这样好像有道理!
