I hope it will be added in the next upgrade. thanks

good idea for state space object 8) , I have a simple suggestion too for this option, to add an other option to spicify lag for AR, SAR order and MA, SAR order, if I would like to estime this model: y c ar(1) ar(3) sar(12) ma(2) sma(24). the option like this: SARIMA order: D: AR: MA: SD: SAR: SMA: s...

I hope there will be a plan for the next version , thanks for your reply

hi, if the next version of EViews 9 can do VMA and VARMAX or not.

I know, but the problem with VMA terme. I can make VARX model but VARMA not is there any way?

This add-in calculates the estimated spectrum of a series object. if the next version will support equation object, state space object, logL object (this is my suggestion). for example I estimate ARMA(2,1) next I chose PROC next add-in next periodogram, the same for state space and logL objects. hav...

hi
is there any way to estimate VARMAX or VARIMAX model in eviews 8 or in next version?
kind regrads

I have simple suggestion, if the next version will calculate and graph periodogram and spectral density with different windows for equation object for ARMA model and for group series, for all objects for example: LogL object state space object...etc?
kind regards.

I have some suggestion, in EViews Estimation ARMA using the backcasting method of Box and Jenkins, or by conditional least squares, why do not put an option to estimate ARMA with a third method like maximum likelihood, and add an option to kalman filter like stata software. 2nd to add option in arch...

thank's for your help and your reply MR startz and MR Glenn.

hi, i have simple question how to add a linear restriction in a model example: cobb douglas production function f(K,L)=A*[K^c(2)]*[L^c(3)] y=f(K,L); A=c(1); log(K)=x; log(L)=z y=c(1)+c(2)*x+c(3)*z 1/i would like to restricted c(3)=0,2 at first and show c(1) c(2) c(3) in output equation 2/second rest...

the significant coefficients can not chow asterisks for GARCH model, can you modified it to chow for GARCH.

hello, I want to know if TSDGP Add-in can generate ARFIMA model (improve TSDGP in the future). second question: are there a function fracdiff to facilitate working with time series data (to make it easier to forecast :? ). third question: for the test ADF can you for example to add option to calcula...
