Migrating from PECL/Stats to Packagist/MathPHP

[A30001881]

Hi Team,

I am currently using below functions from PECL/Stats extension. I have enabled the extension on Azure Web App.

        1. stats_cdf_normal
        2. stats_dens_normal

PECL/Stats does not have a .dll for PHP8. So I am trying to switch to MathPHP
Could you please let me know what are the corresponding functions in MathPHP for above 2 functions ?
Also could you please tell me if MathPHP has dll file for PHP 8.2 ?

Kind Regards
Tharanga

Hi Tharanga,

Thank you for your interest in MathPHP.

MathPHP works with PHP 8.2. There are no system libraries or modification needed to PHP. You can install MathPHP as a standard PHP composer package. Instructions are on the main page.

For similar stats functions, you can check out the MathPHP\Probability\Distribution\Continuous namespace in MathPHP. There are no global functions, but rather individual classes that provide similar functionality. These functions may be what you are looking for:

use MathPHP\Probability\Distribution\Continuous;

$σ = 1;
$μ = 0;
$x = 2;

$normal = new Continuous\Normal($μ, $σ);
$pdf    = $normal->pdf($x);
$cdf    = $normal->cdf($x);
