multicolliniearity in the system (GMM-HAC)?

Hello,
I am dealing with dynamic panel data in simulatnaous system Equations.

In Eviews 7.1, Is there any way to detect multicolliniearity in system after using the system in GMM-HAC option?

Re: p value for J-statistics for simultaneous equation (gmm)

Gareth, Thanks for reply and your help. I am using Eviews system -GMM-Hac For eviews system-gmm HAC, for the following model , total moment conditions is just total instrument number? Could you please help me for it? In 2 equations, I have total 12 instruments (including constant), so total moments ...

p value for J-statistics for simultaneous equation (gmm)

Hello, Could you please help me how I can find p-value for J-statistics in simulataneous equation with GMM? Specifically, I am looking "the degrees of freedom (df)" number for simulatneous equation with GMM method. I could not find how to calculate it. IF I know that, I think I can find p-...

instrumental rank for simultaneous equaion system (gmm)

Hello, In system object (simulatneousg equations) for gmm-hac and gmm-cross secion, there is J-statistics, but there is no instrumental rank info. Therefore, I can cant calculate sargan statistcs p-value and I cannot give a comment for J-statistic. In panel Equation for gmm, Eviews give both J-stati...

instrumental rank for simultaneous equation (GMM method)

Hello, Could you please help me how I can find instrumental rank for simultaneous equations with GMM for panel data? I want to calculate sargan stattistics by using J-statistics. I need instrumental rank for calculation. In Panel Estimation, Eviews give both instrumental rank and J-statistics , but ...

Hansen/Sargan test for simultaneous equations with gmm

Hello, In simultaneous equations for panel data, there is J-statistics for GMM. In manual I found that I can get Sargan test result (p-value) by using J-statistics pval=@chisq(j-statistics, (instrument rank - number of variables)) for panel data. 1) Is it also valid for simultaneousg equation in pan...

Re: Dynamic Panel Method/Arelleno-Bond

Hello In eviews manual (panel estimation examples), there is manually calculation method for first order auto correlation for panel. - first saving residuals then regress resid on resid(-1) and checking coeefcient whether it is less -0.5 or not. If higher, no first order autocorrelation. There is al...

Hello, I also need those Arellano-bond test for 1 st order autocorrelation (M1) and second order autocorrelation (M2) Is there M1 and M2 test for dynamic panel estimation in GMM in Eviews 7.1? I could not find that option in Eviews Or if there is no that choice automatic, is there any way to do it m...

persistence parameter in EGARCH

Hello all, Do you know how to find persistence parameter in EGARCH? I could not get any info in Eviews 7 manual. In literature, I found that "persistence of volatility is captured by the β coefficient alone in EGARCH specification", but it is not clear whether all absolute of sum β's <1 or...

Re: EqTabs (Equation summaries)

Hello Gareth,
It is very helpful program, thank you

I used EqTabs stack table version for AR MA model (ls y c ar(p) ma(q)) but it did not give the probability values of AR and MA coeffcient, it just gives C's probability. How can I get probabilities of AR and MA coefficienst?
Thanks

Re: ARIMASel (Automatic ARIMA selection)

Gareth, Thank you for reply and your help. It is really helpful program. Is it possible to increase AR and MA to 20 instead of 10? I know, you make reservation some ARMA parameters for SAR and SMA as there is limitation for usage of ARMA parameters in Eviews, but, in case I make 0 to SAR and SMA, Ca...

Re: regression in loop structure and saving results

Thanks Gareth.
But I could not find the translation formula from tstats to p in there?
I am remembering that in Eviews manual I see the transformation formula from tstats to p value, but I could not find it now.
If you know the formula, could you please give it?
