Betreff: st: stack question?
Dear Statalist,
Thank you very much for all of your suggestions on my encode question, I
really appreciated your kind help - my variables have been back into
numerical thanks to you.
I have another question and I was hoping you could help me on that too: I
would like to stack some variables in my dataset but at the same time keep
the rest of my variables - I am trying to code a loop for that but I can't
seem to get it right.
I.e., currently, my dataset currently looks like the following (I have about
100 indices for 15 years and 200 countries):
Indice Year CountryA CountryB CountryC
1 1995 .2 .a .1
1 1996 .36 .12 .45
2 1997 .15 .26 .45
2 1999 .22 .33 .11
3 1995 .a .22 .33
My question is how could I stack my country variables under one column named
"Country" by indice and year, and also have another column that would
contain my values?
so I would have the following:
Indice Year Country Values
1 1995 countryA .2
' 1995 countryB .a
' ' countryC .1
' 1996 countryA
' countryB
countryC
2 1997 countryA .15
' 1997 countryB .26
'
3 1995 countryA .a
1995 countryB .22
1995 countryC .33
Thank you very much in advance for any suggestion, I would immensely
appreciate your help again.
Arina
