Changed also the geometricMean() method to work with the new productN() and product() methods. Unit tests have been unaffected by the change. |

Fixes (finally) an old bug in calculation of the median. Users of any previous version are recommended to upgrade. When I fixed a previous bug in the calculation of the median, I forgot to apply the full fix, so it was calculating an erroneous value for data sets with an odd number of entries. Thanks to Diego Puga for pointing this out. It is good to get bug reports when one is getting old and forgetful. ;-) |

Many changes in the existing methods, and a number of new ones: - Added better error handling. - Refactored existing methods to delegate calculations better - Added value caching for invariant statistical parameters - Added optional parameters to some existing methods to enhance their processing or output. Preserve the original behaviour as default so as not breack backwards compatibility - Added new methods: - center() - studentize() - range() - geometricMean() - harmonicMean() - product() - productN() - percentile() - quartiles() - interquartileMean() - interquartileRange() - quartileDeviation() - quartileVariationCoefficient() - quartileSkewnessCoefficient() - Added a unit test class based on PEAR::PHPUnit |

Explicit casting of parameters passed to pow() to circumvent the warnings/errors given by some versions of the PHP interpreter. Thanks to Stephen Evans for pointing this problem out. |
