distr (version 1.5)

Dirac-class: Class "Dirac"

Description

The Dirac distribution with location $l$, by default $=0$, has density $d(x) = 1$ for $x = l$, $0$ else.

Objects from the Class

Objects can be created by calls of the form Dirac(location). This object is a Dirac distribution.

Extends

Class "DiscreteDistribution", directly. Class "UnivariateDistribution", by class "DiscreteDistribution". Class "Distribution", by class "DiscreteDistribution".

Examples

D <- Dirac(location = 0) # D is a Dirac distribution with location=0.
r(D)(1)
# r(D)(1) generates a pseudo-random-number according to a Dirac
# distribution with location = 0,
# which of course will take 0 as value almost surely.
d(D)(0) # Density of this distribution is 1 for x = 0.
p(D)(1) # Probability that x < 1 is 1.
q(D)(.1) # q(D)(x) is always 0 (= location).
location(D) # location of this distribution is 0.
location(D) <- 2 # location of this distribution is now 2.
