EXPONDIST


Calculates values for an exponential distribution.

Syntax:

EXPONDIST(x, λ, mode)

The exponential distribution is a continuous probability distribution, with parameter λ (rate). λ must be greater than zero.
If mode is 0, EXPONDIST calculates the probability density function of the exponential distribution:



If mode is 1, EXPONDIST calculates the cumulative distribution function of the exponential distribution:


Example:

EXPONDIST(0, 1, 0)
returns 1.
EXPONDIST(0, 1, 1)
returns 0.
