Many thanks for your support….CrunchEconometrix loves to teach, help me stay online.
I'm now writing an essay for an econometrics course, and your videos rescued me a lot! Box-Jenkins videos were the most understandable among all I've seen, and VAR ones are also great. Thank you very much!
Dear Ngozi, You are doing a great job, i like the way you put your explanations, easy to understand, you are a great my great tutor! i do have one suggestion though, could you please number your tutorials? sometimes it is not easy to tell whether there is a previous tutorial or next. Once again, keep up the good work, spread the knowledge!
Hi Anthony, thanks for the positive feedback on my videos. Deeply appreciated! 💕 Yes, I number my videos and I always mention the prerequisite videos to watch in all my presentations. Kindly share my Channel link with your students and academic networks. May I know where you are reaching me from?
Hi Florence, thanks for the encouraging remark. Deeply appreciated! Procedure for a bivariate VAR is the same as in any multivariate VAR. May I know from where (location) you are reaching me?
Thanks for your generosity for providing such useful tutorial, if I understand you well, is this what you mean The T-stat LNRGDP(-1) showed highly significant 7.68 which means a 0.99% increase on LNGDP for a 1% increase in LNGDP(-1). Similarly, The T-stat LNEDS(-1) showed highly significant 2.04 which means a 0.31% increase on LNGDP for a 1% increase in LNEDS(-1).

Hi Phillip, thanks for the positive feedback on my videos. Deeply appreciated! 💕 Strong exogenous influence is when other variables in the VAR model do not influence movement in the outcome variable. No industry guidelines as to the percentage. But any figure below 50% should do. May I know from where (location) you are reaching me?

Hi, this video was very informative! I have a question regarding the p values and coefficients I have obtained after running a VAR - some of my variables show a statistically significant p-value (less than 0.05) however they have a negative coefficient and negative t-statistics. What is your opinion on this? How shall I go about interpreting these results? Or is my model wrong? Fortunately this is only occurring to my control variables and not my variable of interest.
I like your video. Thank you. My question is in regards to the endogenity-exogenity terms. Regarding the terms under "From other variables", should the first one, "Strongly Exogenous" not be "implies strong influence on dependend variable"?. Or is it true to say "implies weak influence on dependend variable"?
Hi Okan, thanks for complimenting my video, deeply appreciated. The interpretation is correct. Remember that VAR is an endogenous model, so if other variables have weak influence on the outcome variable, it implies that those other variables exhibit "strong exogeneity"....may I know where you are reaching me from?
@@CrunchEconometrix That's right. I am from Turkey. I am also Phd studen in France. I taught Finance at Rennes School of Busines and at Rennes Campus of Coventry University. I am also finance practicioner. I am commodity trading expert.
When you do Var decomposition (multivariable process) with 2 lags, would it be meaningless to do bi-variate VAR and interpret results? Or the VAR model should also be multivariable?
Hello. Thank you so much for your tutorial! It is helping me a lot right now. :) But I am just wondering, in writing the VAR model, do I have to write the full model (even some of the coefficients are not significant) or I just need to present the model with only the significant coefficients included? Thank you so much!
I think you mixed up your queries. You specify a model BEFORE estimation and coefficients (significant and not significant) are obtained AFTER estimation
@@CrunchEconometrix what if I already specified the model, but after estimation, some of the obtained coefficients are not significant. Can I still use the nonsignificant coefficients in substituting to the specified model? P. S. Sorry if I have too much question.
Hi Ngozi thank you so much for your videos, i just have a question, how can you tell by the t-statisic what a variable is significant or not? What do you compare the t-statisic to?
Hi Davtians, thanks for the positive feedback on my videos. Deeply appreciated. The regression output is based on a 2-tailed test using the 95% confidence interval at which a t-stat of 1.96 is considered to be significant at the 5% level. However, because many students often get confused about the t-stat, I encourage the use of the p-values which gives the exact level of significance at which the H0 can be rejected...may I know from where (location) you are reaching me?
Hello. thank yo for uploading these good and very informative videos. I want to make you request that can you please make videos for estimating structural VAR (SVAR) and specifically how to impose restrictions. I am learning it these days but your help in this regard would be highly appreciated. Many thanks
Hi Fatima any helping results do you have for your question? I have to understand the SVAR model and how to apply restrictions to finish my Dessertaion. Best Regards
Thank you for the video. A 93,2% increase on real GDP? GDP almost doubles after a 1% increase em GDP(-1)?! does this make sense? or am I understanding this wrong? or is the variation of GDP in period t-1 responsible for 92,3% of the variation in period t?
Hello Dr, please in presenting your VAR results is there a need to presents all the results of the other dependent variables. in my case i have one dep. variable and three indep. variables. Do i need to presents the other independent variables being used as dependent variables?
Mam for running VAR model, our variable should be stationery at the same level. Is it necessary only for endogenous variables or also for exogenous variable. If all our variable are stationery at same level, but one exogenous variable are not, then we can run Var model or not. Please clarify

Hello CrunchEconometrix team, thank you for the great efforts. My question is about the S.E. column, how to interpret it and its role in the model?

very helpfull tutorial. i appreciate. but my principal preoccupation is how to run GMM model througt eviews?
You may need to check other online resources.
Thank you for the explanation ma. For the VAR estimates, how do you know when the results are significant?
Use the t-stat like I mentioned in the clip. I'll refer you to any basic econometrics textbooks for more info on hypotheses testing and inferences.
thanks for the head up😍

You scientifically interpret based on the outcome of your estimation. You can then find the intuition for it.
I agree with Pedro. Bosede means a 0.932% increase for a 1% increase.
Thanks for the clarity PJ, that was definitely a slip from me. Gracias!
Hello Dr, please in presenting your VAR results is there a need to presents all the results of the other dependent variables. in my case i have one dep. variable and three indep. variables. Do i need to presents the other independent variables being used as dependent variables?
The choice is yours really. You can report on all or only the main variable of interest. Also, check papers that used VAR and adapt their style.
hi!! we do not have to invert the signs??
Hi Andrea, not sure what you mean.
Mam for running VAR model, our variable should be stationery at the same level. Is it necessary only for endogenous variables or also for exogenous variable. If all our variable are stationery at same level, but one exogenous variable are not, then we can run Var model or not.
Please clarify
Hi Shubham, ALL the variables MUST be integrated of order one. I will advise you watch my VAR videos. Thanks.
