[Limdep Nlogit List] one and one-half bound dc cvm

[유진채]

I have been working with one and one-half bound ditchotomouse cvm and have problem to get computer output using limdep program. The input code and output and error massages are like followings;

name list; bh=one, ubid; bl=one, lbid$
 PROBIT ; lhs=res1
 ;rhs=one , bid1$
name list; bh=one, ubid; bl=one, lbid$
maximize ;label= B1, B2
  ;start=b
  ;maxit=100
  ;fnc=
  PBH=PHI(-dot(bh))|
  PBL=PHI(-dot(bl))|
  yY*LOG(1-PBH)
  +YN*LOG(PBH-PBL)
  +nN*LOG(PBL)$

--> name list; bh=one, ubid; bl=one, lbid$
--> maximize ;label= B1, B2
      ;start=b
      ;maxit=100
      ;fnc=
      PBH=PHI(-dot(bh))|
      PBL=PHI(-dot(bl))|
      yY*LOG(1-PBH)
      +YN*LOG(PBH-PBL)
      +nN*LOG(PBL)$
Error:   212: SURE or 3SLS:EQn=list. n is invalid, nonpositive or > 20

Any advice would be
appreciated.
 Thanks
