I am pleased to announce the second public release of stats for Python, and the first targeted at Python 3.x.
http://pypi.python.org/pypi/stats stats is a pure-Python module providing basic statistics functions similar to those found on scientific calculators. It has over 40 statistics functions, including: Univariate statistics: * arithmetic, harmonic, geometric and quadratic means * median, mode, midrange, trimean * mean of angular quantities * running and weighted averages * quartiles, hinges and quantiles * variance and standard deviation (sample and population) * average deviation and median average deviation (MAD) * skew and kurtosis * standard error of the mean Multivariate statistics: * Pearson's correlation coefficient * Q-correlation coefficient * covariance (sample and population) * linear regression * sums Sxx, Syy and Sxy 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
