[程式] Model is not full rank,線性相依?(SAS)
[軟體程式類別]:
SAS
[程式問題]:
資料處理ˇ
[軟體熟悉度]:
低(1~3個月)
[問題敘述]:
跑完回歸後result出現以下這段話
Note: Model is not full rank. Least-squares solutions for the parameters are
not unique. Some statistics will be misleading. A reported DF of 0 or B means
that the estimate is biased.
我的model是
Y=CEO_Accexp+TOT_Incentive+CEO_Accexp*TOT_Incentive
其中CEO_Accexp為Dummy,非1即0
想請問
1.問題是出在程式還是回歸模型? (我認為有可能是線性相依,但太久沒碰計量了= =)
2.full rank是什麼意思?
[程式範例]:
proc reg data=CEO_Incentive_1_Y4_RegTable;
where accrual_error NE . and CEO_ACCEXP NE . and TOT_Incentive NE . and
CEO_ACCEXP_TOT NE .;
model accrual_error=CEO_ACCEXP TOT_Incentive CEO_ACCEXP_TOT;
test CEO_ACCEXP=0, TOT_Incentive=0, CEO_ACCEXP_TOT=0;
quit;
