求助，用froniter4.1做sfa超越对数生产函数模型时怎么算不出来结果!?-经管之家官网！

本人小白一枚，近两天由于论文刚刚步足SFA。现在想做一个最简单的，但是不知道怎么就是算不出来数先是数据：

序号	时期	lny	lnL	lnK
1	1	11.05	13.43182553	13.91407897
2	2	11.22	13.49639561	13.92982171
3	3	11.45	13.52443741	13.98196896
4	4	11.52	13.60503024	14.37108883

t	(lnL)^2	(lnK)^2	t^2	lnL*lnK	t*lnL	lnK	t*lnL	lnK
1	180.4139371	193.6015936	1	186.8914812	13.43182553	13.91407897	193.6015936	13.91407897
2	182.1526944	194.0399328	4	188.0023845	26.99279122	13.92982171	388.0798656	13.92982171
3	182.9104072	195.4954559	9	189.098264	40.57331223	13.98196896	586.4863678	13.98196896
4	185.0968478	206.5281943	16	195.5190982	54.42012095	14.37108883	826.1127772	14.37108883

再是设置文件：
2 1=ERROR COMPONENTS MODEL, 2=TE EFFECTS MODEL
dx.dta DATA FILE NAME
dx1.out OUTPUT FILE NAME
1 1=PRODUCTION FUNCTION, 2=COST FUNCTION
y LOGGED DEPENDENT VARIABLE (Y/N)
4 NUMBER OF CROSS-SECTIONS
4 NUMBER OF TIME PERIODS
4 NUMBER OF OBSERVATIONS IN TOTAL
9 NUMBER OF REGRESSOR VARIABLES (Xs)
y MU (Y/N) [OR DELTA0 (Y/N) IF USING TE EFFECTS MODEL]
7 ETA (Y/N) [OR NUMBER OF TE EFFECTS REGRESSORS (Zs)]
n STARTING VALUES (Y/N)
IF YES THEN BETA0
BETA1 TO
BETAK
SIGMA SQUARED
GAMMA
MU [OR DELTA0
ETA DELTA1 TO
DELTAP]
NOTE: IF YOU ARE SUPPLYING STARTING VALUES
AND YOU HAVE RESTRICTED MU [OR DELTA0] TO BE
ZERO THEN YOU SHOULD NOT SUPPLY A STARTING
VALUE FOR THIS PARAMETER.
