Cointegrating Regression

Dear all,

I have a doubt regarding to cointegrating regression. In my three variables, Two are I(1) and one is I(2). Estimating the cointegrating regression how have i put the equation on Equation Specification?

Shall i to put lx ly lz or d(lx) d(ly) d(lz,2) ?

Yours Faithfully

insufficient number of observations eviews

Dear all,

When i am testing the cointegration test or even estimating the VEC model the eviews shows up with "insufficient number of observations" and i dont know why.

If you could help me , i would appreciate that kindness

Convert variables I(2) to I(1)

Dear all,

I am testing unit root test and several series/variables present seccond differences or series I(2). However, i want to convert these series I(2) to I(1)

How can i Converth them in Eviews software?

Re: SVAR

For instance,

Killian (2010) writes et=A0^-1 εt , and Basher et al (2011) writes Aut = εt,

This way, if i want to follow one of them, i have to put my matrix restrictions in field A and B as a identity matrix. Am i correct?

Thank you for your time and consideration trubator.

Best regards

SVAR

Hello, I am with a doubt about SVAR matrices. Thus, in EViews the expression is Ae=Bu , for short-term. However, i am folowing Basher et al (2011) since the expression is Au=e ( "u" are the reduced - form errors and "e" strucutural shocks). As in eviews the matrice A is incorpora...

Re: commands Error

Trubator,

in the beggining of my codes i replaced to" %equation_cointeg=%dowjones +" "+"c"+" "+ %brentoil" and then
to calculate de equation cointegration i put equation cointeg.ls(h) {%equation_cointeg} and , even so, it doesn t work.

:(

Re: commands Error

But with that command it doesn t show me up no equation of cointegration in my eviews "environment"

The next commands that i have are:

i) cointeg.makeresids residcointeg
ii)series z=residcointeg(-{%d})
iii)sort z

Re: commands Error

someone help me

i wrote equation cointeg.ls(h) {%equation_cointeg} but the eviews keep showing me up the same message

"alpha series in specification - %dowjones c %brentoil - @EXPAND can convert to catagorical dummies in cointeg.ls(h) %dowjones c %brentoil%

why??

Re: commands Error

when i write : equation cointeg.ls(h) {%equation_cointeg}

as you wrote

the Eviews show me up " Alpha series in specification -DJ- @EXPAND can convert to catagorical dummies" and i dont know why
