note 84680 added to ref.stats

There are some undocumented functions in this extension, eg I found the following by reading the DCDFLIB docs and some trial and error: <?php /** * stats_cdf_normal($x, $mean, $sd, 1) * @return float cumulative probablity */ echo stats_cdf_normal(1.96, 0, 1, 1) . "\n"; /** * stats_cdf_normal($p, $mean, $sd, 1) * @return float x which bounds cumulative probalility $p */ echo stats_cdf_normal(0.975, 0, 1, 2) . "\n"; // less useful // echo stats_cdf_normal(0.4,0.5,0.6,3) . "\n"; // echo stats_cdf_normal(0.4,0.5,0.6,4) . "\n"; ?> ---- Server IP: 92.48.74.199 Probable Submitter: 87.86.250.33 ---- Manual Page -- http://www.php.net/manual/en/ref.stats.php Edit -- https://master.php.net/note/edit/84680 Del: integrated -- https://master.php.net/note/delete/84680/integrated Del: useless -- https://master.php.net/note/delete/84680/useless Del: bad code -- https://master.php.net/note/delete/84680/bad+code Del: spam -- https://master.php.net/note/delete/84680/spam Del: non-english -- https://master.php.net/note/delete/84680/non-english Del: in docs -- https://master.php.net/note/delete/84680/in+docs Del: other reasons-- https://master.php.net/note/delete/84680 Reject -- https://master.php.net/note/reject/84680 Search -- https://master.php.net/manage/user-notes.php
