I am pleased to announce the first public release of stats for Python. http://pypi.python.org/pypi/stats
stats is a pure-Python module providing basic statistics functions similar to those found on scientific calculators. It currently includes: Univariate statistics including: * arithmetic, harmonic, geometric and quadratic means * median, mode * standard deviation and variance (sample and population) Multivariate statistics including: * Pearson's correlation coefficient * covariance (sample and population) * linear regression and others. This is an unstable alpha release of the software. Feedback and contributions are welcome. -- Steven D'Aprano -- http://mail.python.org/mailman/listinfo/python-list
