Hi

I have a set of data like this:

    *Time of Day* *Pct of Daily Volume* 9:45 7.50% 10 6.25% 10:15 4.45%
10:30 4.80% 10:45 4.45% 11:00 4.20% 11:15 2.50% 11:30 2.30% 11:45 2.25%
12:00 2.45% 12:15 2.60% 12:30 2.00% 12:45 2.05% 13:00 2.40% 13:15 1.90%
13:30 3.10% 13:45 2.90% 14:00 2.80% 14:15 2.50% 14:30 3.40% 14:45 4.40%
15:00 5.40% 15:15 4.00% 15:30 4.70% 15:45 6.20% 16:00 8.50%

I want to fit a curve to the data and get the best function fitted,
therefore I can calculate the integral of the function.
How can I do that?

Thanks,
Shirin
