Hi SAS Experts,
I have a dataset consisting three variables - Questions, Dummy, Score. The variable "Dummy" consists of two values - either 0 or 1. I want to restructure the dataset.
The current data set is shown below -
Questions | Dummy | Score |
q7 | 0 | -0.17 |
q7 | 1 | 0.085 |
q8 | 0 | -0.24 |
q8 | 1 | 0.085 |
q9 | 0 | -0.19 |
q9 | 1 | 0.07 |
q10 | 0 | -0.22 |
q10 | 1 | 0.077 |
q11 | 0 | -0.21 |
q11 | 1 | 0.043 |
q12 | 0 | -0.28 |
q12 | 1 | 0.08 |
The desired formatted data is shown below -
Questions | 0 | 1 |
q7 | -0.166 | 0.085 |
q8 | -0.242 | 0.085 |
q9 | -0.187 | 0.07 |
q10 | -0.222 | 0.077 |
q11 | -0.206 | 0.043 |
q12 | -0.278 | 0.08 |
Please let me know if you have any query(s). Any help would be greatly appreciated!
Thanks in advance
Use proc transpose..
proc transpose data=have out=want (drop=_name_);
by Questions notsorted;
id Dummy;
var Score;
run;
try this,
data have;
input Questions :$10. Dummy : Score ;
cards;
q7 0 -0.17
q7 1 0.085
q8 0 -0.24
q8 1 0.085
q9 0 -0.19
q9 1 0.07
q10 0 -0.22
q10 1 0.077
q11 0 -0.21
q11 1 0.043
q12 0 -0.28
q12 1 0.08
;
run;
proc transpose data =have out=want(drop=_name_);
by questions notsorted;
id dummy;
var score;
run;
Depending on the setting of system option VALIDVARNAME, the new variables will be named _0 and _1 (VALIDVARNAME=V7) or 0 and 1 (VALIDVARNAME=ANY), respectively. A variable named 0 needs to be adressed as '0'n in the following code, which may be a hassle.
May I ask why you want to do this transformation?
Most data manipulation, reporting and analysis is easier to do with your original lay-out.
