exponentialDistribution -- exponential distribution

Synopsis

Usage:

exponentialDistribution lambda
Inputs:
- lambda, a number, the rate parameter (positive);
Outputs:
- a continuous probability distribution,

Description

The exponential distribution, the waiting time between events in a Poisson process, where lambda is the expected number of events in one unit of time.

i1 : X = exponentialDistribution 0.25

o1 = Exp(.25)

o1 : ContinuousProbabilityDistribution

i2 : density_X 2

o2 = .151632664928158

o2 : RR (of precision 53)

i3 : probability_X 3

o3 = .527633447258985

o3 : RR (of precision 53)

i4 : quantile_X 0.4

o4 = 2.04330249506396

o4 : RR (of precision 53)

i5 : random X
