" Maybe you could you collapse with if and by?"




I think there was enough -by()- to go around in my line

*******
collapse (firstnm) var1 var2, by(country year)
*******

What do you want to add to that? What kind of -if- qualifier do you have in mind?

Thanks to your help, Martin, I got rid of my initial probelm, but 
unfortunately I'm still not totally happy with the result.
Now my dataset looks like follows:

country     year       var1       var2    var3
A                  x            1             .           .
A                  y            2             .           .
A                  x             .             3          .
A                  y             .             4          .
A                  x             .              .          5
A                  y             .              .          6

But I would like to have all the observations for the different 
variables of the same country and year to appear in the same row, like

A                 x             1            3           5
A                 y             2            4           6

Thanks in advance

Mareike

You could also try:


*************

clear*

inp country:mylabel str4 variable int year obs, auto
  A var1   2000   3
  A var1   2001   4
  A var2   2000   7
  A var2   2001   11
  B var1   2000   13
  B var1   2001   32
  B var2   2000   23
  B var2   2001   34
end

compress
list, noo

gen var1=obs if variable=="var1"
gen var2=obs if variable=="var2"

collapse (firstnm) var1 var2, by(country year)
list, noo

Betreff: st: Reorganization of pael data

Dear Statalist,

I have a panel dataset that is structured the following way:

country variable year observation
  A        var1   x   obs_A_var1_x
  A        var1   y   obs_A_var1_y
  A        var2   x   obs_A_var2_x
  A        var2   y   obs_A_var2_y
  B        var1   x   obs_B_var1_x
   .
   .
   .

But I want it to be structured as followed:

country year var1 var2
    A    x
    A    y
    B    x
    B    y

Is there a command for transposing the data like that?

Thanks in advance

Mareike
