Type: SystemDouble
A single point in the distribution range. For a univariate distribution, this should be a single double value. For a multivariate distribution, this should be a double array.

Return Value

Type: Double
The probability of x occurring in the current distribution.

The Probability Density Function (PDF) describes the probability that a given value x will occur.

The Normal distribution's PDF is defined as PDF(x) = c * exp((x - μ / σ)²/2).
