Type: SystemDouble
A single point in the distribution range.

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 Cauchy's PDF is defined as PDF(x) = c / (1.0 + ((x-location)/scale)²) where the constant c is given by c = 1.0 / (π * scale);
