| Exp-class {distr} | R Documentation |
The exponential distribution with rate λ has density
f(x) = lambda e^(- lambda x)
for x >= 0.
C.f. rexp
Objects can be created by calls of the form Exp(rate).
This object is a exponential distribution.
img:"Reals":
The space of the image of this distribution has got dimension 1
and the name "Real Space".param:"ExpParameter":
the parameter of this distribution (rate), declared at its instantiation r:"function":
generates random numbers (calls function rexp)d:"function":
density function (calls function dexp)p:"function":
cumulative function (calls function pexp)q:"function":
inverse of the cumulative function (calls function qexp)
