[Numpy-discussion] non-standard standard deviation

2009-11-29 Thread Dr. Phillip M. Feldman
All of the statistical packages that I am currently using and have used in the past (Matlab, Minitab, R, S-plus) calculate standard deviation using the sqrt(1/(n-1)) normalization, which gives a result that is unbiased when sampling from a normally-distributed population. NumPy uses the sqrt(1/n)

Eloi: take a look at , which contains a discussion on, and a patch for, not embedding manifest files in *.pyd when compiling with MSVC. You could recompile the PYD/DLL files that depend on the VC90.CRT in winSXS with the patch applied, or manually remove the ma

[Numpy-discussion] convert strides/shape/offset into nd index?

Hi all, I'm curious as to what the most straightforward way is to convert an offset into a memory buffer representing an arbitrarily strided array into the nd index into that array. (Let's assume for simplicity that each element is one byte...) Does sorting the strides from largest to small
