Please help me to improve the code. Thanks

timyu — Mon, 29 Jun 2015 20:52:16 GMT

1. the code is same for each year. Can we use a loop?

2. I want to use 1% 9% 10% ... to split the group. In this code below, I have to split the group manually for each year. Is there an easier and efficient way to do that?

Thank you very much!!!
