st: VEC command and aconstraints option

[Kevin Amess <Kevin.Amess@nottingham.ac.uk>]

Hello,

I am having a problem with placing constraints on adjustment parameters in a VECM model.

When I run:
constraint 1 [D_leqlibor]LD.llbovalue_real=0
vec llbovalue_real lgfcf_bi_real lFTSEallshare leqlibor if tin(1979q1,), lags(2) aconstraints(1)

I receive the following error message:
[LD.llbovalue_real] not found
r(111);

Could anyone advise as to what I am doing wrong?

Kevin.
