Re: st: Question on data management
the question is, how your data look like but I suppose you have individual
data, i.e. for each child a row, so this might help:
I have the children data that includes household id, children's age and
children's birth date.
Using this information, I want to create new three variables;
1. Age difference between children
2. Preceding birth interval
3. Succeeding birth interval
Could you help me how to calculate these new three variables?
Thanks for your kind help in advance.
