Data Conversion to Stationary. Model Two. EVIEWS

[@prof.m.k.sukumarannair4203]

Prof. Hossain is very clear in his exposition.His slowness is a blessing to us who listen to him. I will be attending to all his lectures on econometrics. His classes are extremely useful to those who are not familiar with the packages.

"I can make joom for you"- Man I love your explanation! Was perfect!

[@barbragwokyalya7097]

Wow! Thanks prof,this is the best video tutorial series I have ever seen on the internet. Thanks for your kindness free tutorials. Amazing and God bless you. I don't need to pay anyone to learn EViews.

[@sayedhossain23]

You have to convert all variables (dependent or independent) into stationary and use the stationary data to run a regression model.

Very clear and useful video even 10 years later :)

[@Nico-ij6ef]

Thank you very much.Was very nice that you spoke slowly to understand everything.

[@sayedhossain23]

Nicolae Stan Thank you. I spoke slowly so that everyone can understand my voice. However please join Hossain Academy Facebook below so that we can communicate better. Thank you Sayed Hossain from Hossain Academyfacebook.com/groups/hossainacademy/

He is amazing. Great. He has made me understand econometrics models.

First of all thank you so much sir. It really help me to do my thesis.

[@sayedhossain23]

You are most welcome

Hi! One question. Suppose I have a non stationary monthly time series and after applying the ADF test I find that equation 3 (random walk with drift and trend) makes the series stationary, i.e. the constant and trend, as well as several lags are significant. What is the next step? Should I run an OLS regression of the first difference of my variable on a constant, a trend and all of the significant lags (12 maybe), then get the residuals and save them and work with that time series? Or after running the OLS regression should I pick the estimated values of the constant, the trend, the resulting residual series and the significant lags and then generate a new series with those values?

[@trialzzz]

Hello Sayed, I have got 2 questions. I would like to know why some figures turn into negative after having made the data stationary? Also, I would like to know why some data appears as NA after the conversion? The conversion seems to totally cancel some data.

[@marwanassar5028]

sorry for bothering you sir, i used the l-jung test for a variable in my model for a sample of 22 obseravtions and lags 10 , and took the first and second yet probabilities are still less than 5%, so what should i do? thank you

[@MagicFireDragon66]

Hey, nice vid! Do you perform this test on only the y(dependent) variable or also on all the x(explanatory) variables?

[@everyonesmeow]

Hi I have a question. If I have a time dummy, e.g. 0 for some period and 1 for some period.. and I have first differenced other variables to make them stationary, then what should I do with the dummy? should i also first difference the dummy?

[@sayedhossain23]

candychu Dummy keep it as it is. You do not need to differenced dummy

[@everyonesmeow]

Sayed Hossain thank you!

Video is nice. I want to set a seasonal model of three year dam water level data. I dont know how to do seasonal differentian. can you please tell me steps to go for fitting the model.

[@sayedhossain23]

In future I have planned to do this type of video

[@saadidhothar1129]

Sir what's command for 2nd difference. please tell me . my data is non stationary at first level even.

[@jaffarabbas3437]

also tell me if in ARDL there is serial correlation and functional form test also fails, can we ignore them ?

[@sayedhossain23]

You can not ignore serial correlation test under any circumstances. Better you do not report functional form test result.

[@m.walidhemat6319]

Hi, Do we need to test all variables, dependent and independent, for stationarity or we should just use this test for dependent variable?

[@shenyingzhang5280]

What if the data is still in-stationary after first differencing?

[@jigsmeizter]

hi sayed... how do you get the 2nd difference? what command do i type? pls pls reply.. my variable is stationary in the 2nd difference..

[@sayedhossain23]

Eviews command: DX1=d(X1), DX2=d(DX1)

Thank you sir!

[@montassarkahia3136]

Hello Sayed; Firstly, I want to know how to run the error correction model in case of panel. Secondly, how can I distinguish between the short time causality and the long time causality on the output? And to say that exist bidirectional or unidirectional causality. I need your help. Best Regards

[@sayedhossain23]

I have not done it also yet

[@montassarkahia3136]

hallo sayed please think about panel var (p-var). it is original now. God bless you

[@sayedhossain23]

I have not done anything with panel error correction model yet but will do in future...

[@mohamad27kh1]

Hi, Thank you so much for complete describe. I just have a question. I have a problem for using my data in time series model. my data has trend and are not stationary. I use first difference but it did not work and I used second diff but it also did not work. So my professor suggested me to use residual of my data as stationary data. what is your opinion in my case? can it work or not? I would be realy please if you can help me in this case.

[@amaokine8212]

I have four variables which are not stationary, after 1st difference, three of the variables are now stationary but the last one, i have to difference it twice thus 2nd difference before it became stationary. Can i use all the four variables with1st and 2nd difference in my study?

[@jaffarabbas3437]

hi Sayed your videos are awesome and I am getting very god information from your videos. I am having a problem which I want to discuss with you. I am estimating my ARDL model in eviews and one of my variable was stationary on second difference. I took first difference and its working fine now. Do You think I can take first difference of my independent variable and then use ARDL ?

[@getachewguadie9541]

[@zulqarnainmushtaq9972]

ASALAM ul KUM Sir; I had taken log of all five variables and now all five variables are stationary at second difference (NONE). Is it possible to proceed to next test with variables stationary at second difference or need to transform the variables to make them stationary at first difference then can proceed to next test? I'll be using ARDL model to test the long run relationship then to VECM followed by Granger Causality test. I am really struck jazakallah if you can help me to proceed.

How we calculate exponential growth rate ( For example: major principal crops) when time series data are non-stationary. Please reply urgently or upload a video on this topic.

[@pk1st714]

Sir u should not be sorry for talking slowly...it actually helps us in learning

[@ddplop1100]

Mr.Sayed, this word Sayed In arabic means the leader or the man of the ppl, thanks for your videos , I learned a lot from you , I am doing the misalignment of exchange rate , using seven fundamental variables , GDP , OPEN TOT NFA GOVex And two more dummy variables, And I am running a PMG estimators model. except GDP all other variables are stationary at level. GDP is stationary at the first different. when I use the GDP, I get very small R square, and no sense for my results, but if I use DGDP i get high R square, with consistent results , but not significant DGDP, my question is: when reporting , should I say that it is in the first different , and when running the regression shall i use the the DGDP or the GDP? i am confused thank you in advence

Badly explained. You must keep all learners at the same level. You are behaving as though you have taught them and now walking them through, very bad. I did not see what you were typing when converting variable "a" to log form. You should improve on your tutorials. Bye
