stats_dens_normal — Probability density function of the normal distribution
$x
, float $ave
, float $stdev
) : float
Returns the probability density at x
, where the
random variable follows the normal distribution of which the mean is
ave
and the standard deviation is
stdev
.
x
The value at which the probability density is calculated
ave
The mean of the distribution
stdev
The standard deviation of the distribution
The probability density at x
or FALSE
for failure.
