rvmeanunif: The distribution of the mean of uniform random variables

Description Usage Arguments Details Value Author(s) Examples

Description

The distribution of the mean of uniform random variables with each of them in the interval (-1, 1), then scaled and shifted.

Usage

1
rvmeanunif(n = 1, mode = 0, scale = 1, df)

Arguments

n

Length of the vector to output

mode

Mode (center) of the distribution

scale

Scale (half-width) of the distribution around the mode

df

"degrees of freedom": number of independent components to average

Details

Assuming that all inputs are constants, each generated variable has a mode (center) at mode, constrained between (-scale, scale).

The shape becomes more and more bell-shaped (Normal) as the number of the independent variables in the sum (mean) increases.

The case of df=2 (mean of two variables) is the special case of the symmetric triangular distribution in the range

Value

A random vector of length n.
