This function returns the value of a student-T-distribution with the total area of 1.
$dfr are the degrees of freedom for that distribution (aka k)
$x is the X-Value for which the value should be returned

stats_dens_t — Probability density function of the t-distribution
Description
stats_dens_t
( float
$x
, float $dfr
) : float
Returns the probability density at x, where the
random variable follows the t-distribution of which the degree of
freedom is dfr.
Parameters
-
x -
The value at which the probability density is calculated
-
dfr -
The degree of freedom of the distribution
Return Values
The probability density at x or FALSE for failure.
