时间Tue Apr 26 21:36:23 2011
大家好
我是用SAS跑panel模型
不知道这个error的意思是什麽
ERROR: Not enough observations with non-missing model variables for model
statement in cross section company=11.
还有是因为什麽出了问题?
以下是我的log档
34 proc sort data=ratpo;
35 by company financial_year;
36 run;
38
39 proc panel data= ratpo;
40 id company financial_year;
41 model tgpw_growth=changerbc lnta dummy_stock dummy_group dummy_mutual
longtail_ratio_npw / fixonetime ;
42 run;
ERROR: Not enough observations with non-missing model variables for model
statement in cross section company=11.
NOTE: The SAS System stopped processing this step because of errors.
NOTE: PROCEDURE PANEL used (Total process time):
real time 0.58 seconds
cpu time 0.32 seconds
麻烦大家了 谢谢^^

3F：→ linlowmoon:原本以为unbalance的话 自动就会设定missing data 04/27 21:48
4F：→ h0h1:我都手动删除耶，写程式先算出观测对象的长度如果是1就删掉 04/27 22:15
