How do you do ARMA-Egarth model in Eviews? Or even PARCH, TARCH, EWMA or GARTH??? I tried doing Quick>Estimation> dlogreturn c ar(1) ma(2), as I have previously identified my arma model as AR(1) and MA(2), however, I keep receiving error messages: ARCH estimation requires a continuous sample? The on...

Hi, I have identified an ARMA model (1,2) but I was wondering whether it is possible to include a dummy variable for a structural break on Eviews, and how would you forecast it?

How would you go about doing it?

What happens if your ARMA model has a very high JB value (non-normality), do you need to transform the data and redo everything (start the box-Jenkins methodology again)? H
ow would you transform the data if necessary?
Does the ARMA model typically give high non-normal residual?

Trying to conduct the Breush-Godfrey test using ARMA (1,2) however, keep receiving the error message: not available with this estimation method (ARMA ML). What does this mean? Did I do something wrong? What could be wrong with the data to receive this result?

For the first-stage F you want the reduced form. Wouldn't you get the same generalised equation but like different letters instead? How would you do it with so many variables? What difference does it make? Cause I did get an answer but I think I did it the structural formula way and get a low F-sta...

For the first stage of the equations would you just input LS of the structural equation for equations 1 and 2 to get the F-stat or would you input the reduced form equation to get the F-stat?

That looks correct. So it's probably a problem with your data. Could it not be something to do with the second equation having 1 additional variable compared to equation 1 or that the variable X2 exists in both equations? Nope. The former means that the first equation is overidentified and the latt...

How would you do it when there is an unequal number of variables in the two equations. I am sure the equation is over-identified so 2sls should work right, or at least produce some results from half the equation?

Show us the commands you use and maybe attach the EViews workfile. Quick, Estimate Equation, 2sls Equation specification: Y1 c Y2 + X1 + X2 + X3 + E Instruments: XI X2 X3 X4 X5 X6 I think I got near a singular matrix for this one. How are you meant to do 2sls when you got 2 simultaneous equations w...

How do you let Eviews know which variables are endogenous and which variables are exogenous in tsls, and the variables that form the 2 equations?

Say I got 2 equations: (1) Y1 = Alpha + Y2 + AX1 + BX2 + CX3 + E (2) Y2 = Beta + Y1 + DX4 + BX2 + FX5 + GX6 + U How would you do the 2sls? I keep getting singular matrix error messages or insufficient instrument variables? I have been inputting equation 1 as model specification and X1, X2, X3, X4, X...
