Hi, Josef,
Thanks very much for the quick and helpful response.
Could you also comment on the use of lstsq(): Why it leads to inconsistent
result?
Cheers, Anthony

Hi, all,
It is probably a newbie question.
I trying to use scipy/numpy in a finanical context. I want to compute
the correlation coeff of two series (returns vs index returns). I tried
two appoarches
Firstly,
from scipy.linalg import lstsq
coeffs,a,b,c = lstsq(matrix, returns) # matrix con

Is there a Numpy windows help file?
Cool!
But where is it? I can't find it in my numpy 1.2.1 installation?!?
I like the Python 2.5 Windows help file too and I agree it is a fast

Yes, this is exactly what I was after, only the function name did not
ring a bell (I still cannot associate it with something meaningful for
my use case). Thanks!

Hi Numpy discussions
Quite often I find myself wanting to generate a boolean mask for fancy
slicing of some array, where the mask itself is generated by checking
if its value has one of several relevant values (corresponding to
states)
So at the the element level thsi corresponds to checking if

Indeed, even more so for C.
