img
Object of class "Naturals"
:
The space of the image of this distribution has got dimension 1
and the name "Natural Space".
param
Object of class "PoisParameter"
:
the parameter of this distribution (lambda), declared at its
instantiation
r
Object of class "function"
:
generates random numbers (calls function rpois)
d
Object of class "function"
:
density function (calls function dpois)
p
Object of class "function"
:
cumulative function (calls function ppois)
q
Object of class "function"
:
inverse of the cumulative function (calls function qpois).
The quantile is defined as the smallest value \(x\) such that
\(F(x) \ge p\), where \(F\) is the distribution function.
support
Object of class "numeric"
: a (sorted)
vector containing the support of the discrete density function
