Re: ARDL - Trend Specification

I think Igor is right. It's time to end this discussion. Before we do however, there is something to be said about peddling "strong" authors and "common in the literature" practices. The reason @EnjoFaes and @mickeykozzi are confused is because they are reading articles without h...

Re: ARDL - Trend Specification

In the last 7 days, you seem to have been involved in more than 6 different EViews Forum threads related to ARDL questions. All are related or revolving around the same general idea. Most of the questions you've been asking have been answered by myself and/or Igor, or, you have been guided to the or...

Re: ARDL/ECM Bounds test question (EVIEWS11)

The original authors of the ARDL bounds test, namely Pesaran, Shin and Smith (2001) (PSS henceforth) have the following advice in their paper: Two sets of asymptotic critical values are provided for the two polar cases which assume that all the regressors are, on the one hand, purely I(1) and, on th...

Re: ARDL/ECM Question

There appears to be 2 methods in finding ARDL and ECM... I'm not aware that there are multiple approaches to expressing the contemporaneous ARDL form into its EC equivalent. They are both equivalent representations of the same underlying structure. However, the ARDL model is typically estimated via...

Re: ARDL/ECM Question

Hi, So how do I find the residual results for the ECM/ARDL? Bth the original ARDL and the parsimonious ECM/ARDL use the same seated mod, so I'm guessing they have the same residual result??? The residuals from the contemporaneous and the ECM model are identical. All inferences on the residuals gene...

I suggest you start by reading our blog series on ARDL estimation.

Yes. The Johansen test is done on the VECM representation.

Re: Vector Error Correction Model (VECM)

Why do you need peer-reviewed journals to show this? You can do so yourself directly. It's pretty rudimentary. I'll give you the case for p = 1 and p = 2. You can use mathematical induction or a brute force method to demonstrate the general case. VAR(1) => Y_t = Gamma * Y_{t-1} + Beta * X + eps_t = ...

Re: ARDL Model Estimation Problem

Hi! The reason that you don't see the constant or trend terms in the long-run levels equation is due to the fact that you are estimating ARDL using the deterministic scheme 5 which does not subject the constant and the trend to the long-run restriction. In other words, the constant and trend are NOT...

Re: ARDL Substituted Coefficients

Ah! I think I understand your point now. What you are claiming is "incorrect" is in fact the Error Correction Form (ECM) of the ARDL model. And you are right! The ECM is NOT equal to the cointegrating equation that we display in the outputs we have pasted earlier, namely. Cointegrating Equ...

Hi Jamel, I'm not entirely sure how you're obtaining that output, but when I run the estimation on my end, the output I receive is: ---------- Estimation Command: ========================= ARDL @FL(REALCONS,1) @FL(REALGDP,1) @ Estimation Equation: ========================= REALCONS = C(1)*REALCONS(-...

Re: EViews 11: DHF seasonal unit root test

Hi! At the moment we've chosen to only support HEGY, Likelihood HEGY, Canova-Hansen, and the Variance Ratio seasonal unit root tests. Following Ghysels, Lee, and Noh (1994) we've decided against initial support for the DHF test. This is by no means a permanent decision and we may in fact decide to s...

Re: ARDL model - ECM regression

What form of the ECM were you expecting? Theoretically transforming the ARDL equation to an ECM equation results in the form you are seeing in the EViews output. I suggest you take a look at our 3-part blog series on ARDL estimation to understand why this is the case. This conversion from the ARDL e...

Re: Unit root test for autocorrelation

To determine if residuals are serially correlated, you must use tests designed to test for this specifically. The most famous of these tests is the Durbin-Watson, but you should probably use the LM tests proposed by White, Breusch-Pagan-Godfrey, Harvey, and so on. Note that if you are testing for un...
