Re: Splitting up vectors

Thank you, this was similar to that what I figured out in the meantime. It worked perfectly. I still have two questions: 1) Did I understand the estimation right, when I said that the 53 estimates for each exogenous are the estimates from the cross-sectional regression in every point t between 1 and...

Splitting up vectors

Dear all, I have estimated a pooled estimation (32 firms over 53 weeks) in the following manner: firmpool.ls y? @perreg 1 @perreg beta? Now, I have 106 estimated coefficients (for every exogenous one estimate in each period). Following the Fama-MacBeth procedure, I am interesed in the averages of th...

But anyway, the original question was why does the arch not simply ignore estimations in which missing values arise? Is there a reasonable explanation?

Handling missing values/NAs

Hello everybody, I have a question regarding the way EViews treates missing values. Currently, I am writing a small program to estimate the market betas of 38 firms. I use a loop with 38 diagonal BEKK models, each with the return of one firm and "the" market to find the conditional covaria...
