This functions will be the equivalent for "DISTR.NORM.N" on excel, like an other user said it's for Gaussian normal distribution.
$x as value to analyze
$ave as average
$stdev as deviation

stats_dens_normal — Probability density function of the normal distribution
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.

I'm not certain that I've figured this one out correctly but it should return the value of a (Gaussian) normal distribution of the given properties at the given location.
$x - the X-Value to request
$ave - the 'expected value' (i.e. location of the peak) for the distribution. For most uses this will just be 0.
$stdev - the standard deviation of the distribution. For most uses this will be 1.
