mrstab {alphastable} | R Documentation |
mrstab
Description
generates iid
realizations from bivariate stable vectors using the methodology proposed by Modarres and Nolan (1994).
Usage
mrstab(n, m, alpha, Gamma, Mu)
Arguments
n |
sample size |
m |
number of masses |
alpha |
tail index parameter |
Gamma |
vector of masses |
Mu |
location vector |
Value
a vector of n
numeric values
Note
mrstab()
assumes that masses are located at unit sphere with addresses s_j=(cos(2*pi(j-1)/m), sin(2*pi(j-1)/m))
; for j=1,...,4
.

Examples
# We use the following command to simulate n=200 iid vectors from a two-dimensional stable
# distribution with alpha=1.3, with a vector of 4 masses as gamma=(0.1,0.5,0.5,0.1)^T,
# and mu=(0,0)^T.
