Panel Generalized Method of Moment (GMM) in Eviews (Dynamic)

[@naeemkhan4246]

thanks alot for the efforts. is there any video in which you gave applied GMM for mediation analysis. kindly share the link

[@ChekwubeMadichie]

Not yet

[@ononiwukelechiclinton2596]

Please what is the solution to this? Kindly give a video or explanation to demonstrate this issue I had while running the gmm what does this mean kindly explain 'number of instruments greater than number of observations'

[@vaishnavibalaji6811]

Sir i have run three models. In that for two models AR(1) and AR(2) p values are shown as NA. And in the third model pvalue of AR(1) is 0.963. please explain sir most of the AR p values are shown as NA. What does it mean. Does it mean it's a bad model

[@mohamedseddiksakai9447]

how did you work to graduate a model panal generalized method , i did not show me this model just model generalized method and in this model there is on test bond seriel and there a problem with an application @DYN ??

[@rizalaelatsaro4496]

Hello thanks for your video. I dont know how to input data excel to eviews on this process. Is it the same as entering data in panel data?

[@ChekwubeMadichie]

You should first arrange your data in Excel and then copy to the Eviews to set up your workfile or you can set up a workfile in Eviews and then input your data manually. I will make a separate video for that.

[@ChekwubeMadichie]

Dear Riza Laela Tsaro, you can now watch how to input time-series and panel data into the Eviews workfile @ kzbin.info/www/bejne/ap3Ucnmvhs2Zirc

[@barbragwokyalya9483]

Thanks for the detailed explanations. At what point do we have descriptive statistics and correlation analysis? What comes first? diagnostic tests for normal distribution, unit root, serial correlation, heteroskedasticity, multicollinearity or all these are catered for by the regression estimation? I observe that differencing/lagging caters for unit root, endogeneity is also managed here. When is the co-integration test done? What if n if less than t? what estimation techniques should be used? How do we establish whether data requires internal instrumental variables?

Hello thanks for sharing the valuable information.

Welcome

[@ismailaganiyou7879]

Hello Professor, Thank you for this very rich video for us first-time researchers. I am currently performing an analysis and need to use the Generalized Moment-Based Regression (GMM) method. I wanted to know how to determine the number of lags to include in the endogenous variables.

[@ChekwubeMadichie]

There's no formal procedure for determining the number of lags to include as instruments for endogenous variables. Lag 1 is usually the default for instrumenting the endogenous regressors while lag 2 of dependent variable is used to instrument the predetermined regressor (ie lag 1 of dependent variable).

[@mahesadavaw]

Why there is no Intecept in the regression? please help

[@ChekwubeMadichie]

A constant is specified but it doesn't come visible in the results.

[@gudinagoda6945]

Thanks for your helpful video tutorial. I want to ask you if we should test the unit root in the Panel Generalized Method of Moment (GMM)? If our variabes are of different order of integration (some are stationary at level and some are stationary after first difference), can we use the Panel Generalized Method of Moment (GMM)?

[@lequotidien5441]

Hello Pr. How can we interprete J-statistic in output of panel System GMM ? How can i obtain sargan-Hansen test with eviews? How can we interprete the output of system GMM model? When you have two equations. I work with eviews 10. Thanks !

[@nazialatif5112]

Very helpful and informative lecture. Thank You so much, sir. Please can You tell us how to find the Wald test statistics and Hansen test for instruments?

[@khaledzubdeh1326]

Hi. thanks for the valuable information, I tried on my model but keeps rejecting it and giving msg that: Number of instruments greater than number of observations. what do in this case? thanks again

[@ChekwubeMadichie]

Revisit the instrument specification and follow my guidelines in the video. If the problem persists, re-estimate with fewer instruments. Also, be mindful of the size of N and the number of k as you specify the instruments.

Can the time series data be used in gmm in eviews? If possibe how the data be arranged for gmm? Please help me

[@ChekwubeMadichie]

Yes, the data is time series. You can arrange in excel and copy to Eviews or set the data up from Eviews. You need to know how to set up the cross-section ID and date ID. It's very simple.

[@mdnaiemhossain6074]

@@ChekwubeMadichie thanks..actually i am totally new in gmm method. And my data is time series..so i face some problems. I wish a vedio based on time series data not panel data in eviews..

I have other videos on time series data analyses. Except you're talking about country-specific time series GMM, there are videos on time series on my channel. I will make a video on country-specific time series GMM soon.

Sir , The autocorrelation at AR(1) should be significant whereas AR(2) should be insignificant (Beck et al., 2013 and Roodman, 2009). May i please know what must be the pvalues for AR(1) and AR(2)

[@ChekwubeMadichie]

The pvalues for AR(1) should be less than 0.05 (significant) while that of AR(2) should be greater than 0.05 (insignificant) for that condition to be met.

[@moyosoreadedapo-aisida9802]

Is system GMM the same as orthogonal deviation?

[@ChekwubeMadichie]

No, they're not the same. However, if the instrument condition is met, the usual system gmm can be estimated with the forward orthogonal deviation transformation.

[@ChekwubeMadichie]

The instruments must be strictly exogenous and must have larger impact on the regressors. I will make a video on two-step.

[@afnanghanayem7016]

Hello and thank you, should I apply diagnostic tests on panel data set before starting GMM? if yes which tests I should apply?

You should start with endogeneity test and sargan test of overidentifying restrictions.
