Hi all,
I am wondering how could I write the code as to transform the way the data is presented. Currently, I have the following:
Firm 1 0.001
Firm 1 0.023
Firm 1 0.002
.... ....
Firm 4058 0.000
Firm 4058 0.001
Firm 4058 0.000
Firm 4058 0.001
I would like to transform the presentation such that the Firm 1 to 4058 are unique variables (columns) under which I have their returns:
Firm 1 .... Firm 4058
0.001 0.000
0.023 0.001
0.002 0.000
0.001
I am a beginner in SAS and couldn't find examples on the internet. Hope my issue is explained clearly.
Many thanks,
You probably need another variable to make it easy.
So add a ROW counter and then sort the data.
data fix ;
set have ;
by firm ;
row+1;
if first.firm then row=1;
run;
proc sort ;
by row firm ;
run;
And now you can use PROC TRANSPOSE to flip it around.
proc transpose data=fix out=want ;
by row ;
id firm ;
var value ;
run;
Firm_ Obs row _NAME_ Firm_1 4058 1 1 value 0.001 .000 2 2 value 0.023 .001 3 3 value 0.002 .000 4 4 value . .001
