Class "Unif"

The uniform distribution has density $$d(x) = \frac{1}{max-min}$$ for $min$, by default $=0$, $\le x \le max$, by default $=1$. C.f. runif

Keywords
distribution
Objects from the Class

Objects can be created by calls of the form Unif(Min, Max). This object is a uniform distribution.

Extends

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

Is-Relations

By means of setIs, R knows'' that a distribution object obj of class "Unif" with Min 0 and Max 1 also is a Beta distribution with parameters shape1 = 1, shape2 = 1, ncp = 0.

Examples
U <- Unif(Min=0,Max=2) # U is a uniform distribution with Min=0 and Max=2.
r(U)(1) # one random number generated from this distribution, e.g. 1.984357
d(U)(1) # Density of this distribution is 0.5 for x=1.
p(U)(1) # Probability that x<1 is 0.5.
q(U)(.1) # Probability that x<0.2 is 0.1.
Min(U) # Min of this distribution is 0.
Min(U) <- 1 # Min of this distribution is now 1.
Min(U) # Min of this distribution is 1.
Min(U) <- 0
is(U/2,"Beta") # yes
V <- U/2; as(V,"Beta")
