PHP stats_rand_gen_noncentral_t() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be discussing briefly about the stats_rand_gen_noncentral_t() Function.

The stats_rand_gen_noncentral_t() Function generates a single random deviate from the non-central t-distribution.


Following below is the syntax to use this function -

float stats_rand_gen_noncentral_t( float $df, float $xnonc )

Parameter Details



The degrees of freedoms



The non-centrality parameter

Return Value

This built-in PHP function returns a random deviate from the non-central t-distribution with a degrees of freedoms df, and the non-centrality parameter xnonc.


This built-in function was first introduced in statistics extension (PHP version 4.0.0 and PEAR v1.4.0). In this tutorial guide, we used the latest release of stats-2.0.3 (PHP v7.0.0 or newer and PEAR version 1.4.0 or newer).


The following example below generates a single random deviate from the non-central t-distribution with a degree of freedom set to 2, and non-centrality parameter set to 1 -

   var_dump(is_float(stats_rand_gen_noncentral_t(2, 1)));


When the above code is executed, it will produce the following result -



Following is an error case. In the following example, we have passed df < 0. A warning is shown in logs -

   // error cases
   var_dump(stats_rand_gen_noncentral_t(-0.1, 1)); // df < 0


The above code will produce the following result and a warning in logs PHP Warning: stats_rand_gen_noncentral_t(): df <= 0. df: -1.000000E-1


Alright guys! This is where we are going to be rounding up for this tutorial post. In our next tutorial, we will be studying about the PHP stats_rand_gen_normal() Function.
