You ought to give a much clearer excerpt of your data.

If it is really as simple as the one below, use -egen myrowmiss, rowmiss()- and you can easily drop depending on whether the row has any missings by -drop if myrowmiss >0 & !mi(myrowmiss)-.

Hi and thanks for your response. That's not what I'm looking for. I
will be more explicit.
Supose the folliwing data set with each row represents a panel
observations for a variable:

1 2 3 4 5 6 7 8
. . 3 4 5 6 7 8
1 2 3 . 5 6 7 8
1 2 3 4 5 6 7 .
1 2 3 4 5 . . .

I want to keep only the observations like the first one and drop the others.

Hi Statalisters,

I have a very unbalanced panel data set, composed for a lot of panel
and 12 years. I'm interested in "balance" this panel, keeping only the
panel tha have information for a set of variables in all the period.
How can I do that?

Thanks
