rwrappedstable: Random Generation from the Wrapped Stable Distribution

Description

Generates pseudo-random numbers from a wrapped stable distribution.

Usage

rwrappedstable(n, scale=1, index, skewness, control.circular=list())

Value

Returns a vector of n independent random numbers generated from a wrapped stable distribution.

Arguments

n

number of random numbers to generate.

scale

the scale of the distribution.

index

number from the interval (0, 2]. An index of 2 corresponds to the normal, 1 to the Cauchy. Smaller values mean longer tails.

skewness

number giving the modified skewness. Negative values correspond to skewness to the left (the median is smaller than the mean, if it exists), and positive values correspond to skewness to the right (the median is larger than the mean). The absolute value of skewness should not exceed 1.

control.circular

the attribute of the resulting object.

Details

n random numbers are generated from a stable distribution with with parameters index, skewness and scale. The function returns these values modulo 2*pi.
