Rolling regression with time dummies 13 Dec Hi, for a seminar we want to calculate Enviromental Dynamsim based on Dess, Beard For this purpose the industrial what is dummy variable coding should be regressed against time where time represents a rolling 5-year period as time dummy variable to get the standard error.

We use Stata 14 with all updates. Unfortunatly it's prohitted to publish the data here. We would like to go into each industry and there perform a regression over the sales and as an independent variable a dummy variable of time with a time window of 5 years. Approach 1 is as follows: Code:. Tags: None. Nick Cox. Your Approach 2 should therefore be a loop over industries and definitely not over observations, which would just repeat many regressions to no good end.

But you're looping over sectors and looping over years, which aren't especially difficult. The following sketch might help. Comment Post Cancel. Hello Nick, what is dummy variable coding for your fast answer. Unfortunately, the code of the logic does not fit for us, since at the beginning the average is formed by the sectors. We want to go into every sector and what is dummy variable coding the sales there over the years and not summarize them over a mean before.

Do you have any idea for this? I loop over sectors and all that summarize does is find the identifiers to loop over. There is no averaging. Do try the code and study it. It is close to what you ask for. Your link was to Jacobs, B. Journal of Operations Management, The sentence. Thanks again for your help! We now regressed manually by doing a regression for each of the 31 years with the same logic as you did Dependent Varibable Sales, Independent Variable: Dummy Variable also created manually and the window for years.

We get 31 new variables with the standard errors that we summarized afterwards. I think the logic is the same as yours. Unfortunately your loop didn't work for us and Stata tells us "no observations". It would be nice to compare the results. Last edited by Daniel Held ; 15 Dec Darius Lennart. Hi all, for our calculations covered in our paper we want to do the same procedure as it was done does potato chips raise cholesterol 8.

We understand the logic of the procedure, however we are not sure how the sectors were defined. Are sectors just a placeholder for industries? How are the sectors defined? Thanks in advance. Previous Next. Yes No. OK Cancel. Not helpfull.
