I am tryign to use ARDL for a panel. Dependent variable is renewable energy capacity. For few countries for first few years there was no capacity (therefore 0). Then for few years may be low value (such as 0.7kw per capita). I think i cannot use logarithm for 0 and value below 0 such as 0.7 will become negative when done logarithm. Will it be ok to use values as they are without making them into logarithm for dependent and independent variables. please advise. Thank you.

What if cointegrating equation (speed of adjustment/ error correction term) value is positive and insignificant (In Short run equation panel of ARDL results)? kindly explain

Thank you so much. it is clear and well explained. I have one question please, How can we include regressors being fixed ( for example the initial level of GDP) in the specification. When I do so, I have a message error "Near singular matrix"

Thank you for sharing valuable info. I have one question, when i perform panel ARDL model, the results show error of near singular matrix. what does it mean, i cannot run the regression. waiting for ur valuable suggestions.

Just excellent! Thank you very much for keeping it simple and didactic. When I think how Econometrics was taught 30 years ago this is just a great leap forward allowed by software technologies. Kudos! I have two questions if you allow me: (i) You have not commented the Coeq - 0,88 which I suppose is the Error Correction Term (ECT) and the speed of adjustment to long term equilibrium. Correct? (ii) My rough and outdated knowledge of panel econometrics was based on the use of pooled OLS and the fixed Effect vs. Random approach based on the Hausman Test (1978). Is this approach still valid or totally outdated given its lack of consideration for stationarity analysis which became a central issue in time series econometrics? Best regards.

Thanks sir for this valuable lecture. Please tell while applying ARDL model in panel data, other features of optimal regression equation like high r square and adjusted r square, Durbin-Watson value (near two), significance of Prob(F-statistic ), no serial correlation, No hetroscedasticity and normality of residuals is to be ensured or not need to be checked??

Hi Sir, thank you for the video. I have just a quick question. Could please let me know whether l should look at cross countries coefficients in the short run? Is it not enough to interpret the results you obtained for whole country? Thanks

@@econacademy16 thank your for reply. One more question please. Let's assume that l am looking at the effect of investment on gdp for 10 developing countries in the short and long run. In this case, do l need to interpret the cross countries coefficients in the short run? Actually l could not understand the different between the general regression and cross countries coefficients. Thanks
