j statistic and Determinant residual covariancein Panel GMM

hi. The estimation results shows the j statistic and the Determinant residual covariance. siince the output does not show instrument rank, how can I get the p-value for both the j-statistic and the Determinant residual covariance.

Re: J statistics and GMM

to get the pvalue of the j statistics you use the below:


scalar pval=@chisq(J-Statistic, instruemntrank-nummber of regressors in the model)

my question is how do you execute that command in eviews 8

maximum variables for VAR system

please is there a maximum number of variables to be included in a VAR system? I have 20 variables, using annual time series from 1970-2011.

model performance indicators

when you estimate a system using GMM, what can be used as model performance indicators as R2 is no longer valid

unit root and GMM

do you need to do a panel unit root test in conjunction with the system GMM estimation ? or the time series do not need to be stationary for GMM estimation to yield valid estimates?

comparing regressors

when comparing regressors in the same model, to see which regressor's effect on the dependent variable is stronger; which is more important: the size of their coefficients or their significance levels

date format

Hi all. I am trying to estimate a panel system. however i am using three year averages. what format should the date be in so that eviews can i dentify it. because in excel i wrote 1970-1972, but eviews can indentify it as date. how should i rewrite it

Regressor Endogeneity Test

Dear all,

I cant find View/IV Diagnostics and Tests/Regressor Endogeneity Test when I click on view. using eviews 7.2. what can be the problem? i am using time series data, three-year averages.

3 equation system

hi everyone, trying to estimate a three equation system using 3sls. However, the dependent variable on the 3rd equation keeps giving me a syntax error. so does eviews only estimate 2 equation systems?

instruments for GMM

I have used the lags of the exogenous variables as instruments but get 'near singular matrix' error. What should I do pls. What should the instruments be. I am using GMM estimation. Gdp=c(1) +c(2)*D(gdp)+c(3)*D(D(lab))+c(4)*D(D(londsv))+c(5)*D(D(capflow))+c(6)*D(res)+c(7)*D(D(hcap))+c(8)*inf+c(9)*D(...
