Re: Backtesting

There are no built-in backtesting routines in EViews.

Re: Fama-MacBeth regression

It should be very simple for you to modify the add-in to put the ts regression output into a spool. For example, in the add-in code replace the fragment beginning with "' calculate betas from ts regressions of portfolio/asset returns on market returns" with: ' calculate betas from ts regre...

Re: Fama-MacBeth regression

Don't wait for another update. Now that the add-in is producing the time series coefficients, it should be easier for you to follow Fama-French 1993 methodology.

Re: Fama-MacBeth regression

I've added a line to the Fama-MacBeth add-in to produce the coefficients from the timeseries regressions. The updated program is now available for download and more details are in the documentation.

Re: Fama-MacBeth regression

Thanks for your feedback, but I have no immediate plans to enhance the add-in. To get what you want you could extract the piece of the program that does the first step (the time series regressions) and then modify this to get your time series output.

Re: Fama-MacBeth regression

I can't help you with that. There are many possible risk factors and how you determine them is up to you.

Re: Fama-MacBeth regression

I don't understand what you're asking. The add-in will calculate the betas for you from your risk factors.

Re: Fama-MacBeth regression

The Excel file you posted has 43 observations (including the NAs) but your example shows 50 observations. Where are your extra observations coming from? Also, this isn't necessary to solve your problem, but I noticed you've dropped the date information going from Excel to EViews. Keeping this might ...

Re: Fama-MacBeth regression

Works for me.

By the way, you can also enter the series as "p*" and " rf mk f*" (without the quotes).

Re: Fama-MacBeth regression

If you look at your data you will see that series "p5" has NAs. The add-in will not work with NAs in series. One solution is to change the sample to exclude them.

Re: Fama-MacBeth regression

You will need to make some minor code changes. Change the size of "subbhat" to hold the additional variable, and add it before the cross-sectional regressions are done. Also change the size of "subgamma" to hold the coefficient from the additional variable and the size of the &qu...

Re: Fama-MacBeth regression

1. EViews simply reports the F-statistic. It's up to you to decide what significance level you want.

2. Since the cross-sectional average regression uses robust standard errors, use the robust F-statistic (Wald F-statistic).

Re: Fama-MacBeth regression

There's no such thing as "gamma," as defined in the add-in, for individual portfolios. gamma is a measure of the premium you get from exposure to a certain risk factor. That's why there's one for each factor (plus the constant). I strongly suggest you read the documentation so you understa...

Re: Fama-MacBeth regression

The Fama-MacBeth documentation will answer your questions.

1. See section 2 ("GUI") on how to enter portfolio returns and factors.

2. See equation 2 and surrounding text for the definition and use of gamma.
