Re: Re: st: consecutive observation - incomplete panel data (help)

Maarten, and also Sebastian Buechte, are correct.
Alfred has a spell problem.

Given three variables, a simpler condition than any
mentioned that all are non-missing is

!missing(var1, var2, var3)

Thus Alfred should look for spells defined by
that condition.

Dear Marteen, thank you for your suggestion, but it seems it doesn't 
help me. The link provides useful tricks, but my problem is quite 
different. I mean: starting from a large but incomplete database (three 
variables, from 1980 to 1998), I simply need to restrict my analysis to 
individuals (my units) that have
no missing data (on my three variables) for at least five
consecutive years. Until now I haven't found how to get this selection 
in Stata, and I still hope that you or someone else will help me (an 
example with a basic dataset would be a big hand).

You can find a lot of useful tricks in:

and in the Stata Journal article it refers to.
