Re: Rolling regression with some missing entries

Dear Gareth, thanks for your reply. I think I find my problem. I need to make the rolling window for each firm stops by firm's last non-NA observation, and then carry on the repetition to the next firm. I defined the last non-NA observation by %end=@otod(@ilast(temp{!m})) in the loop. But in the fol...

Re: Rolling regression with some missing entries

Dear Gareth, Sorry for the confusion. My code seems have some problems: error as: insufficient number of observations to estimate equation. Because the ending and starting date of non-NA is different for each firm, so the round is also firm-dependent, so is the dimension of the matrix that holds the...

Re: Rolling regression with some missing entries

Dear Gareth, thanks for you prompt reply. I have tried to program for one firm (firm 10873), whose begining 50 and last 40 observations are NAs. I use monthly data and rolling 1 year ahead every 3 years. '------------------------------------ !window=36 !step=12 !length=@obsrange !nrolls=@round((!len...

Re: Rolling regression with some missing entries

Dear Gareth, I have a similar problem: I try to run the rolling regresssion on each firm data in a pool workfile (360 obs * 300 firms) For each firm: 36 window with 12 step for each firm using firm=c(1)+c(2)*mkt. And loop across all 300 firms. The problem is my pool data is not balanced. So most of ...

Re: Continuous Observations - Panel Data

Dear Gareth, I can re-structure them in a panel. So panel.
Again I really appreciate your time.

Re: Continuous Observations - Panel Data

Dear Gareth,

I have a similar problem, I also have an unbalanced pool containing 800 firms. I need to extract the firms having obs more than 60 and put them in a new workfile. I am stuck in the programing, will you please help me out?

Thanks so much.

Re: panel data extract

All in the same workfile. Does the unstack work in this senario?

Re: panel data extract

Extract the independent time series for each firm into a new workfile. Thanks!

Re: panel data extract

Dear Eviews expert,

I have a similar query: I have an unbalanced panel data set (with cross sectional id and time/date), and I intend to extract the time series for each firm, could you please give me guidance on this?

I really appreciate! :D

Best regards,

Amber

Re: How to compute p-value with Empirical Distribution

Dear Gareth, 1. I ran regression y=c+beta*x, and get the c as empirical_c. 2. I bootstrapped 1000 times on residuals from step 1, to get 1000 bootstrapped c. And also get the bootstrap distribution for boot_c. 3. I want to get the p-value/percentile of empirical c in boot_c distribution. And this is...

Re: How to compute p-value with Empirical Distribution

Dear Gareth, I have run the bootstrap for constant term of the regression for 1000 times, and get the distribution for constant term. Now I want to get the p-value for the empirically regressed constant term (for instance 1.9) on the bootstrapped constant distribution, how can I code it? I have trie...

Re: How to compute p-value with Empirical Distribution

Dear Gareth, I also have the same problem as Tang. But in my case, it is just simply calculate a given dot's p-value of the empirical distribution. Is the p-value for the given dot (suppose it is 2) also the percentile in the empirical distribution? Or different? It so, would you please kindly teach...
