Class "Unif"
The uniform distribution has density
d(x) = 1/(max-min)
for min, by default =0, ≤ x ≤ max, by default =1.
C.f. runif
Objects can be created by calls of the form Unif(Min, Max).
This object is a uniform distribution.
imgObject of class "Reals": The space of the image of this distribution has got dimension 1
and the name "Real Space".
paramObject of class "UnifParameter": the parameter of this distribution (Min and Max),
declared at its instantiation
rObject of class "function": generates random numbers (calls function runif)
dObject of class "function": density function (calls function dunif)
pObject of class "function": cumulative function (calls function punif)
qObject of class "function": inverse of the cumulative function (calls function qunif)
.withArithlogical: used internally to issue warnings as to interpretation of arithmetics
.withSimlogical: used internally to issue warnings as to accuracy
.logExactlogical: used internally to flag the case where there are explicit formulae for the log version of density, cdf, and quantile function
.lowerExactlogical: used internally to flag the case where there are explicit formulae for the lower tail version of cdf and quantile function
Symmetryobject of class "DistributionSymmetry";
used internally to avoid unnecessary calculations.
Class "AbscontDistribution", directly.
Class "UnivariateDistribution", by class "AbscontDistribution".
Class "Distribution", by class "AbscontDistribution".
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.
signature(.Object = "Unif"): initialize method
signature(object = "Unif"): returns the slot Min of the parameter of the distribution
signature(object = "Unif"): modifies the slot Min of the parameter of the distribution
signature(object = "Unif"): returns the slot Max of the parameter of the distribution
signature(object = "Unif"): modifies the slot Max of the parameter of the distribution
signature(e1 = "Unif", e2 = "numeric"): multiplication of this uniform distribution
by an object of class ‘numeric’
signature(e1 = "Unif", e2 = "numeric"): addition of this uniform distribution
to an object of class ‘numeric’
