When to use none?
When Intercept?
When trend?

[@salmanhussain5153]

MashaAllah sir ❤️ crucial information

[@sidrahussain6923]

Thank you very much its great help to understand the concepts. May Allah bless you Ameen

[@takmilahsan]

Thanks for explaining Stationary Series and Unit Root Test in such a nice manner.

[@TJAcademyofficial]

Also See below videos. This will give you more info.

[@johnkoirala]

I really loved all of your concise lecture series. I had so many misconfusion on Statistics (econometrics) but now i am much more confident, i understand the concept well. Thank you so much.

[@TJAcademyofficial]

My pleasure 🙂

[@lochanbatala4410]

Awesome Dr..

[@uttambarua2951]

Excellent clarification

[@mehboobsultana826]

thanks for such a valuable lecture

[@boukhrisazhar2461]

Thannnks again for your hard work .. i am learning many things from you ..
So please sur
I have a panel data
1- what i choose for unit root test ADF/PP or CIPS (cross-Sectional dependent?? I didn't know what is the difference between the two?? (Because in the articles i saw the both methods!!
2- after i do the unit root test, did i use the differences of the variables when for example estimate Var ? Like D(gdp) i(1)

[@OnlineCommerce247]

In multivariate analyses, if some variables are stationary by choosing intercept and some variables are stationary by choosing trend and intercept. Can we run further regression analysis?
Thanks

[@ayadhichem4567]

Ok sir, concerning the series you tested in the video is this series stationary or not??? in the third equation (with trend and intercept) the p-value is less than 0.05 so there is no unit root this what means the stationarity of the series but the series was not stationary in the two other equations and in addition to this the trend coefficient in equation three was significant, so the series is not stationary???

[@surajrout2482]

Thank you

[@usakha02]

how to use this unit root test to determine the lags used to estimate VAR?

[@analysis9394]

sir, how to take unit root result to word and how to fix the data to be stationary

[@gitikaarora7727]

Thank you very much sir

[@chandnirana369]

Sir please make video on BDS test in eviews. There is not even a single video available on this topic. I urgently need its please sir if possible make a short video 🙏

[@dilshadbano5990]

what if the series is not stationary at intercept and stationary with intercept and trend, should we conclude that the series is stationary?

[@mahabubbashas6809]

Assalamu walekum sir,
I have 20 stokcs (Independent variables) and NIFTY 5O INDEX(dependent variable)
Step 1: applied adf test (all variables are stationary at 1 level)
step 2: applied johansen cointegration approach
step 3: Yes if there is cointegration between stocks and nifty 50
step 4: applied vecm model
after this any other analysis can we do sir for risk reduction ?
zajakallah khier

[@chandnirana369]

I hope now I can submit my thesis ..thank you sir..and

[@TJAcademyofficial]

Best of luck for your thesis 👍

[@agha3779]

Mashallah Sir

[@TJAcademyofficial]

JazakAllah

[@geetanjali3436]

Sir is it possible to test the stationary properties of variable without log transformation

[@TJAcademyofficial]

Yes

[@shabbarimam4779]

Sir, if during unit root testing 2 variables are at level and 3 variables are at first difference so which technique we used...ARDL,OLS,Johansen cointegration or someone else?

[@TJAcademyofficial]

Thank you for your message. ARDL is appropriate.
Also watch below video for model selection

hi
i have a question. i am considering a panel data of 30 observations in total (6 banks X 5 years each) and i can't perform the unit root test, saying that there is not enough observations.
what should i do? i can't increase my sample because of unavailability of information.

[@TJAcademyofficial]

Thank you for your message. Stationary analysis is required for long (time series observations) data. Your data are short so need to apply stationary analysis. Find the link below for panel analysis on your data.

[@celebritiesclub534]

If one variable is in second difference so we will transform into log so after put log on such variable in order to comes in stationary or in 1st difference we will again use this log variable in unit root test ????
If 1 variable in second difference and other 4 variables is in 1st difference so we will run Johansen cointegration test Or not ?????????
Plszzz sir guide

[@TJAcademyofficial]

Thank you for your message.
1. Yes, after transformation it should be confirmed.
2. Johansen cointegration assumes that all variables are I(1) or first difference stationary.

[@neelamrathi8850]

Sir what is weak stationary

Jzak Allah sir
Plz intrpret t values

[@annusingh704]

sir, please make a video on,... how to make a series stationary.

[@dilipbjha]

Thank you for this. Further, can you please clarify on followings
1) how to choose between none, intercept and intercept+ trend based ADF test model?
2) what should be decision rule if there is conflicting results. For example, if none and intercept based test shows not stationary and intercept + trends shows stationary of the time series?

[@TJAcademyofficial]

1. You can test with intercept and trend and intercept. None is not considered mostly because majority of the variable related to economic and finance does not have zero initial point.
2. Use another test like PP to confirm.
