Description Author

This class can calculate the mean, variance and deviation of a set of values.

It takes a set of values and perform several types of statistic calculations on them like: mean, sample variance, population variance, sample standard deviation and population standard deviation.

The class can process arrays, objects with the Traversable interface and single values.

As result it can return individual values, associative arrays, of a formatted string in a configurable format.

Details
This package includes the following files:

I recommend installing the DocBlox PEAR package and generating the documentation
that way. From the command line:

$ cd path/to/meansdev
$ docblox run -f meansdev.php -t doc

This software is contributed to the public domain.
