R: Random Generation from the Wrapped Normal Distribution

rwrpnorm {CircStats} | R Documentation

## Random Generation from the Wrapped Normal Distribution

### Description

Generates pseudo-random numbers from a wrapped normal distribution.

### Usage

    rwrpnorm(n, mu, rho, sd=1)

### Arguments

`n` | number of random variables to generate.
`mu` | mean direction in radians of the wrapped normal distribution.
`rho` | concentration parameter. rho must be between 0 and 1.
`sd` | different way of select `rho`, see details below.

### Details

n random variables are generated from a normal distribution with mean direction mu, and variance -2*log(rho). The function returns these values modulo 2*pi. You can set `rho` by using `sd` with the following equivalence:

ρ = \exp{- σ^2/2}

### Value

Returns a vector of n independent random variables generated from a wrapped normal distribution.
