ANN: stats0.1.2a calculator statistics for Python

[Steven D'Aprano]

I am pleased to announce the third public release of stats for Python. 
This is a minor point release, mostly consisting of improved tests and 
documentation, plus the addition of six new statistics functions:

midhinge, quartile_skewness, cumulative_sum, running_sum, stderrskewness, 
stderrkurtosis.

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)
  * skewness 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.
