VECM: Deterministic Factors & t-stat for CointEq in EC

[dada]

Dear users,

I have 1 problem and 1 question.
I apply the VECM for a time series. My dependent variable is default probablity and all variables are I(1).

My problem:
I want to determine the deterministic components for my VECM.
My independent variables have different deterministic components so I can't derive my deterministic factors from theory. Another problem is, that I'm just interested in a cointegration relation of 1 (default probability is the variable I want to explain). So I'm not interested in more ranks than 1. I applied pentula and modified pentula principle but the problem is, I get more ranks and - as said before - I'm just interested in 1 cointegration relation. So, how can I determine the deterministic components of my VECM for rank = 1?

My question:
When I get my VEC estimates does my CointEq1 need to be significant in my Error Correction "D(default_probability)"? What does it mean when CointEq1 is not significant?

Thx a lot,
dada
