Re: Heteroskedasticity test

The White test is in many ways a pecial case of the BPG test. Both tests are appropriate, but the BPG allows more flexibility in modelling the nature of heteroscedasticity by explicitly specifying its functional form.

Re: I(1),I(0) and cointegration

Actually, we have our own three part blog series on ARDL estimation, and your are strongly encouraged to read it. http://blog.eviews.com/2017/04/autoregressive-distributed-lag-ardl.html?m=1 http://blog.eviews.com/2017/05/autoregressive-distributed-lag-ardl_8.html?m=1 http://blog.eviews.com/2017/05/a...

Re: Trend-stationarity and cointegration

Have a look at this document to help you out. Indeed, two trend stationary variables can be co-integrated. What happens, however, is that the cointegrating relationship purges the effect of the deterministic trend. If this was not the case, it would imply the presence of a trend in the cointegrating...

Re: AR and lagged dependent variables

OLS Is just an estimation method which may or may not produce consistent estimates. Although I'm not sure of which mostly in particular you refer to in your post, I am almost certain that the inclusion of an AR(1) term in your regression will not invalidate (in terms of consistency) the OLS estimato...

Re: Estimation of the Dynamic Common Correlated Effects Estimator (DCCE)

The procedures of which you speak are generally termed "second generation" panel models. At the moment, these are not available in EViews. Nevertheless, they are on our to-do list and will be introduced in a future release.

Re: ARDL/ Wald Test Restrctions on Long Run Parameter

You mean Eviews does not have the capability to conduct a long run Wald test using these variables or any other variables at this time? No! EViews has the capacity to do almost anything you want, however, it may not be automated at the moment and you may have to write the program yourself. What I m...

-0.117421 INV** = -0.117421 INV(-1) + 0 D(INV).


No! It means the coefficient on D(INV) is the same as for INV(-1). In other words, -0.117421. I made that explicit in my previous post.

Re: ARDL/ Wald Test Restrctions on Long Run Parameter

Unsure of how to go about this...in re-estimating the ECM, are we to create new variables series to do that? I have a similar issue and I am trying to conduct Long Run Wald test to test for asymmetry on some partial sum first differenced variables similar to the Shin et al. (2014) technique. I have...

I believe this should do it. I've commented the code.

We will describe how to do a Monte Carlo experiment in an upcoming blog post. That would certainly help you get started.

Re: URGENT ARDL interpretation Issue

This just means that if your model has variables which are chosen to have zero lags, they have a special interpretation. In your particular case, for instance, the coefficient associated with INV** is -0.117421. The note basically says that: -0.117421 INV** = -0.117421 INV(-1) -0.117421D(INV). Accor...

Re: time-varying cointegration

At the moment, time-varying nonstationary estimation is not something that is directly supported, but a custom code using kernel weighting can be programmed in EViews. Eventually, we hope to implement native estimation procedures of the type you've mentioned here.

You're right, the
