UniformSupp: Moments and Moment Generating Function of the Uniform Distribution

Description

Raw moments, limited moments and moment generating function for the Uniform distribution from min to max.

Usage

munif(order, min = 0, max = 1)
levunif(limit, min = 0, max =1, order = 1)
mgfunif(x, min = 0, max = 1, log = FALSE)

Arguments

order
order of the moment.
min, max
lower and upper limits of the distribution. Must be finite.
limit
limit of the random variable.
x
numeric vector.
log
logical; if TRUE, the cumulant generating function is returned.

Value

  • munif gives the $k$th raw moment, levunif gives the $k$th moment of the limited random variable, and mgfunif gives the moment generating function in x. Invalid arguments will result in return value NaN, with a warning.

Details

The $k$th raw moment of the random variable $X$ is $E[X^k]$, the $k$th limited moment at some limit $d$ is $E[\min(X, d)^k]$ and the moment generating function is $E[e^{xX}]$.
