Hi all,
I have a problem creating a variable that I think can be solved using some sort of loop but I don't know how to code it. I have an input dataset with information about mortgages, including the maturity for each one. I need to create a variable called year, that creates a line for each year from 0 to maturity for each contract. Therefore, the output dataset will have as many lines as contracts times (maturity +1, accounting for the zeroes). Below I set an example of my input and my expected output, so that it is easier to understand:
Input
CONTRACT_ID | PD | INDUSTRY | MATURITY |
13000 | 0,45 | construction | 3 |
12400 | 0,09 | retail | 5 |
37000 | 0,023 | tech | 2 |
Desired output
CONTRACT_ID | PD | INDUSTRY | MATURITY | YEAR |
13000 | 0,45 | construction | 3 | 0 |
13000 | 0,45 | construction | 3 | 1 |
13000 | 0,45 | construction | 3 | 2 |
13000 | 0,45 | construction | 3 | 3 |
12400 | 0,09 | retail | 5 | 0 |
12400 | 0,09 | retail | 5 | 1 |
12400 | 0,09 | retail | 5 | 2 |
12400 | 0,09 | retail | 5 | 3 |
12400 | 0,09 | retail | 5 | 4 |
12400 | 0,09 | retail | 5 | 5 |
37000 | 0,023 | tech | 2 | 0 |
37000 | 0,023 | tech | 2 | 1 |
37000 | 0,023 | tech | 2 | 2 |
data want;
set have;
do year=0 to maturity;
output;
end;
run;
