Eigenvectors from Principle Component Analysis
I used Eviews and Matlab to extract the factor loadings (eigenvectors) on a dataset. For a particular principle component (PC 3), Eviews shows negative signs on the factor loadings while Matlab had positive signs. Not sure if this is a bug in Eviews. I said this because a commercial software that I ...

What is the command line for copying the eigenvectors from the Principal Component Analysis table into a matrix as a column vector? Thank you.

Do you have any examples or illustrations that can be shared with me? I just want to make sure what I am doing is correct--to be on the safe side.

Principal Component Regression
Hi EviewGareth:
Can Eviews perform principal component regression? I don't see this as an option in the drop down when creating an Equation object.

Does anyone know if Eviews can perform orthogonal regression?

Re: Sample coding for extracting Eigenvectors
Hey Gareth,
My meaning of extract is to save the eigenvectors in a variable. Thanks for pointing out the command reference.

Sample coding for extracting Eigenvectors
Hi,
Can anyone with Eviews programming experience to post sample code on how to extact eigenvectors? One condition: these eigenvectors are computed using ordinary covariances.
Thank you!

Re: Information Criterion
Sorry. My English must be really bad. Allow me to try it again.
Is there a way to run stepwise regression with the option of using a specific information criterion such as AIC or BIC? I know this can be accomplished in R. I don't see such a flexibility in Eviews.

Information Criterion
Using Eviews version 7.2. I would like to know if there is a way to run OLS using information criterion such as AIC, BIC, or adjusted R^2. I think I am right by saying that this cannot be accomplished directly using the GUI interface. I imagine this has to be done using the command line. Can someone...

Re: Recursive estimation
I meant:
Using observations from 1990M01 to 1999M12 to estimate 2000M01(forecast). Then using observations from 1990M01 to 2000M01(actual) to estimate 2000M02.

Re: Recursive estimation
Gareth, If I have a recursive regression that estimates the following: 1) Estimate 2000M01 using observations from 1990M01 to 1999M12. 2) Estimate 2000M02 using observations from 1990M01 to 2000M01. Follwing your logic, for 1) I would set the sample period as follows: 1990M01 to 2000M01? And 2) 1990...

Recursive estimation
Hi, I am struggling with doing this task in Eviews. I have an OLS equation with one independent variable (of lag 1). The sample period is from 2000M01 to 2001M12. Once I have this estimated equation, I go to View-->Stability Diagnostics-->Recursive Estimates (OLS only), I clicked on the Recursive Co...

Re: Rolling Regression Forecasting
Hi, I know there is an existing rolling regression add-ins for Eviews. However, I am looking for a rolling regression add-in that performs rolling regression AND have the model selects the given regressors that maximizes a selection criterion (like Akaike) for one-step forecast. Is there such an add...

GARCH(1,1) example in help file
Hi,
Eviews help file provides an example of GARCH(1,1) model of the first difference of log daily S&P 500 (DLOG(SPX)). The sample period is from 1/2/90 to 12/31/1999. So the estimated variance from this model is for 1/2000, right?
