Package to calculate statistical parameters of numerical arrays of data. The data can be in a simple numerical array, or in a cummulative numerical array.

A cummulative array, has the value as the index and the number of repeats as the value for the array item, e.g. $data = array( 3=>4, 2.3=>5, 1.25=>6, 0.5=>3 );

Nulls can be rejected, ignored or handled as zero values.

This is old code I wrote for PEAR. Originally it was tracked in CVS, then it was moved to SVN, and now I am importing it to git :-)
