(PECL stats >= 1.0.0)
stats_dens_f — Probability density function of the F distribution
Description
float stats_dens_f ( float $x , float $dfr1 , float $dfr2 ) Returns the probability density at x, where the random variable follows the F distribution of which the degree of freedoms are dfr1 and dfr2.
Parameters
x
The value at which the probability density is calculated
dfr1
The degree of freedom of the distribution
dfr2
The degree of freedom of the distribution
Return Values
The probability density at x or FALSE for failure.
