[Numpy-discussion] Is there a function to calculate ecnomic beta coefficient in numpy given two time series data.

Timeseries1 = daily or weekly close of stock a
Timeseries2 = daily or weekly close of market index (spx, qqqq, etc)
Beta of stock a is what I would like to compute as explained in this article
on Wikipedia:
http://en.wikipedia.org/wiki/Beta_coefficient
I'm trying to compute the beta of entire stock market (about 15,000
instruments) one stock at a time and would like to use the spiders and qqqq
to represent the overall market.
Thanks,
Vineet
