StatsExpPDF

StatsExpPDF (x, µ, σ)

The StatsExpPDF function returns the exponential probability distribution function

$$\displaystyle f(x ; \mu, \sigma)=\frac{1}{\sigma} \exp \left(-\frac{x-\mu}{\sigma}\right),$$

where µ is the location parameter and σ > 0 is the scale parameter. Use µ = 0 and σ = 1 for the standard form of the exponential PDF. It returns NaN for σ = 0.
