Sir, how u convert fdi into fdlr(growth rate). In ARDL MODEL how can we apply HAC test? Autocorrelation, multicollinearity and heteroscedacity Is important or not in ARDL?
Very informative video sir, As a beginner like me this video helps me a lot, but i have a query if time series data have auto correlation where does impact or what will happen to time series.
Thank you for your message. If autocorrelation exist in time series regression, it effects standard error (SE) of coefficient. Then SE effects t-statistics (Coefficient/SE) and ultimately prob value changes. Change in prob values will effect the decision of significance of variable. It means in presence of autocorrelation, significance of variable is not reliable. If model shows any variable is significant or insignificant, might be the results are opposite. I hope you got the answer of your question. Feel free to contact me if you have further question.
After applying HAC test sir your Durbin watson value is 0.37 which shows autocorrelation exists because its between 0-2.. I didn't it?? You meant to say after applying HAC text we dont need to see durbin Watson value ???? And sir if prob value is 0.051 so we need to go towards removals of autocorrelation or not ??????? Kindly help . I would be very thankful to you
After applying HAC test, there will be no need to see DW. If LM test shows 0.051 prob then there is NO AUTOCORRELATION at 5 percent level of significance.
Hi can you please further clarify/elaborate of HAC test. Post HAC did not see any change in the either coefficient values or DW value. That what does it exactly do? further in that case can I run further run LM test to see it autocorrelation is removed?
Just noticed it changes t values. So if I simply try to understand the problem and HAC solution 1) Autocorrelation : does not give reliable T and P values 2) HAC test : does not adjust coefficient value or it basically adjusted t and P value to see of the coefficient is significant 3) The model shall still fail LM test as HAC test does not addresses auto correlation but basically adjust the T and P value to reconfirm the reliability of these estimates Is my understanding right?
Thank you for your message. Actually HAC correct standard error of estimates. It's leads to change t and prob value. No more confirmation is required if sample is large.
@@TJAcademyofficial thank you so much for quick revert. One more doubt after getting this clarification from u. what if if sample size is 12-15 data point. or in this case would would be rough cut sample for not doing further diagnostic?
@@TJAcademyofficial thanks for your reply, sir. Does it make sence to check autocorrelation for panel data? If l am using fixed effect, should l check autocorrelation??

great video, your way of teaching is easy to understand, keep making more videos.
Thank you sir..your way of teaching is superb..your lectures help me lot .
I am really very greatful to you
Thank you so much for this video, it really helped!!!
Sir u are amazing JAZAK ALLAH
Nice explanation. How to test autocorrelation with panel data? As the steps you provided can not be performed with panel data? Thank you
Sir, how u convert fdi into fdlr(growth rate).
In ARDL MODEL how can we apply HAC test?
Autocorrelation, multicollinearity and heteroscedacity Is important or not in ARDL?
Good morning sir 🙏Sir can u plzz begin with Econometric software GREtl ??
Sir jazak Allah
Please tell me, how can i add "serial correlation LM test" ? I dont find it in my eviews
Sir serial correlation for LM test is not available in my Eviews 12. can u please guide what to do.
awesome tutorial
Thank you
Sir if in ARDL or Johnson case we face autocorrelation can we apply HAC qnd how to apply sir

Why did you set lag at 1, not 2 as default??

Could i know should we look at the DW table to determine the range?
Sir how we can get eviews software from you??
R^2 > DW. It is spurious regression
Thank you for your message. Yes it is but the focus is autocorrelation here
why do you put lag 1?
Because of the assumptions of Durbin Watson
sir kindly explain endogeneity with eviews and also panel data analysis with eviews
Hi, please could you explain the difference between partial and serial autocorrelation? Thnaks
Hello, did you mean ACF and PACF?
@@TJAcademyofficial yes, l mean that
Let's consider lag 3.
In ACF all lag are included
In PACF only 3rd lag is considered.
@@TJAcademyofficial thanks for your reply, sir. Does it make sence to check autocorrelation for panel data? If l am using fixed effect, should l check autocorrelation??
Sirji please make videos on these:
ACF and PACF
White noise
ARMA model
Pleaseeee🙏🙏🙏
Thank you for your message. Currently working on Cointegration. Will covers these topics after that
@@TJAcademyofficial okay thanks
Will wait for these videos
@@TJAcademyofficial sir do you provide online coaching?
Depends
@@TJAcademyofficial okay on what it depends? I need to learn these
plz explain what is autocorrelation first before you go to the analysis, ppl need to understand first.
thanks
