Documentation/How Tos/Calc: EXPONDIST function

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.
