I work for a bank. There are 2 groups of accounts chosen randomly when they
were booked. Those 2 groups of accounts are comprised about 20% of the
whole portfolio. One group is called the champion and the other is called
the challenger. The champion has the same strategies as the rest of the
whole portfolio, except the challenger, which has different stratgies. We
try to have the challenger outperformed the champiom for at least 6 months,
so we can implement the same strategies to the rest of the portfolio, then
create a new challenger. I want to perform a statistical test (maybe
t-test)to conclude that the challenger has outperformed the champion overall
in a 6 month period. Should I use their average performances such as
profits or revenues each month for 6 months (n=6 for the challenger and n=6
for the champion, each month for each group is a data point or (n)), or
should I compare by using each individual account each month for 6 months
(n=10,000 accounts for the challenger, n=10,000 accounts for the champion).
I apologize if my question is too naive; I took only 1 statistics class.
Any suggestion, idea for the test or forcasting is greatly appreciated.
Sincerely,
John Anderson
