hi, thank you for video
i have a question, when we run a unit root test, why the coeff of d(oil(-1)) should be negative?
thx in advance.

Dear Professor,
your tutorials are really helping us. I have learnt a lot especially ARDL model through your videos. I would like to suggest that if you can develop more videos on Sarima, Farima, ARCH, Garch etc... going to be massively beneficial to people in the academic circle.I am from Sri Lanka. Pls. think of what I suggested to you. Also Panel data, monthly data, Using STATA and so on.

Hello Professor. I have a question, when I change the value of the maximum lags in the ADF test on my monthly data my results change. How do I know how many max lags should I use?

Hello sir.... If the series does not become stationary even after 2 difference. Then what to do

thank you, professor, please, I have a question.
When we do a panel unit root test, is it needed to determine the (lag) as we do in cointegration test or not?.

Hi, , can we change the amount of the maximum length besides still choosing and using AIC?? For example, in your vid is 15, so can we change the amount to 10 or 5 maybe?

Professor, may I humbly submit one request? I have learned that for working with non-stationary time series there is an approach by the name of Cochrane-Orcutt iteration method. Can you make a detailed video on the topic while showing how it is done in eviews? How the results are to be interpreted etc?

professor can we apply correlation analysis to a deat which is stationary at first difference but partialy with intercept and partialy without it?
