Description:
------------
The E_NOTICE says that the code itself try to increment an element of an array, but this element has no value.

File : PEAR/Math/Stats.php
Version : Math_Stats-0.9.0beta3
Line : 1216

It does $freq["$val"]++;

I added the following just before :

if (!isset ($freq["$val"]))
{
$freq["$val"] = 0 ;
}

$ diff Stats.php Stats_modified.php
1215a1216,1218
> if (!isset ($freq["$val"])) {
> $freq["$val"] = 0 ;
> }
