stats_dens_normal

Probability density function of the normal distribution

Description

float stats_dens_normal(float $x, float $ave, float $stdev)

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.

Parameters

x

The value at which the probability density is calculated

ave

The mean of the distribution

stdev

The standard deviation of the distribution

Return Values

The probability density at x or false for failure.
