Dear Stata specialists
I am quite a rookie at Stata. I want to summarize my data into 5 year periods. I have a data set with over 120 countries and my time period is from 1980 to 2010. Now I want to create the averages for 5 year periods (1980-1984; 1985-1989; 1990-1994; ...).
The problem is, that my panel is UNBALANCED, so there is data MISSING at some points. So for example when there are just 3 values avaiable in a 5 year periode I just want to have the mean of these 3 values.
My data set looks like that:
and in the end it has to look like that:
Can you please advise me on the code I can use for this? I am writting on my bachelor thesis and it is really important.
Thank you very much in advance![]( "Smile")
