Hi,
I have a dataset with multiple ID's that I want to reduce to unique ID's through their respective weightings.
For example, the dataset below shows ID, some additional variables required (Var1, Var2) and the weighting (wt).
id | var1 | var2 | wt | AR_Q0 | AR_Q1 | AR_Q2 | AR_Q3 | AR_Q4 | AR_Q5 |
1 | xx | 345 | 0.5 | 10 | 11 | 12 | 13 | 14 | 15 |
1 | xx | 345 | 0.3 | 50 | 51 | 52 | 53 | 54 | 55 |
1 | xx | 345 | 0.2 | 20 | 21 | 22 | 23 | 24 | 25 |
2 | df | 321 | 0.7 | 30 | 31 | 32 | 33 | 34 | 35 |
2 | df | 321 | 0.1 | 40 | 41 | 42 | 43 | 44 | 45 |
2 | df | 321 | 0.2 | 50 | 51 | 52 | 53 | 54 | 55 |
I need to create multiple each AR_Qx value by the weighting and sum up the rows by ID so it looks like this. For example AR_Q5 is calculated as (15*0.5)+(55*0.3)+(25*0.2)=29
id | var1 | var2 | AR_Q0 | AR_Q1 | AR_Q2 | AR_Q3 | AR_Q4 | AR_Q5 |
1 | xx | 345 | 24 | 25 | 26 | 27 | 28 | 29 |
2 | df | 321 | 35 | 36 | 37 | 38 | 39 | 40 |
What is the most efficient way of performing this calculation. At the moment I am doing this in Excel.
Note: Unfortunately I am unable to modify the source dataset as it is part of another process.
Thanks in advance.
proc summary data=have;
class id;
id var1 var2;
var ar_q0-ar_q5;
weight wt;
output out=stats sum=;
run;
proc summary data=have;
class id;
id var1 var2;
var ar_q0-ar_q5;
weight wt;
output out=stats sum=;
run;
Thanks Paige!
