我有数据格式如下，
date time product value1 value2 value3
..

..
there are 10 different type of product. we call it P1, P2, P3, P4,....P10
I want to calculate Min/Max, mean, std of value1/2/3 for given product
in a range of datetime.
so my input is,
dataset, $product, $begin_datetime, $end_datetime
output is,
min/max, mean, std
Thanks for your help！
