Random generation for some symmetric continuous distributions.
rvgs is used to random generation from some standard symmetric continuous distributions.
rvgs(n, family, xi)
n |
number of observations. |
family |
Supported families include Normal, Student, Contnormal, Powerexp, Hyperbolic, Slash, Sinh-normal and Sinh-t, which correspond to normal, Student-t, contaminated normal, power exponential, symmetric hyperbolic, slash, sinh-normal and sinh-t distributions, respectively. |
xi |
a numeric value or numeric vector that represents the extra parameter value of the specified distribution. |
x |
a vector of n observations. |
