law0030.FoldedNormal {PoweR} | R Documentation |
Random generation for the Folded Normal distribution with parameters mu
and sigma
.
This generator is called by function gensample
to create random variables based on its parameters.
If mu
and sigma
are not specified they assume the default values of 0 and 1, respectively.
The Folded Normal distribution with parameters mu =
μ and sigma =
σ has density:
f(x) = 1/(√(2π) σ) e^-((-x - μ)^2/(2 σ^2)) + 1/(√(2π) σ) e^-((x - μ)^2/(2 σ^2))
for x ≥ 0.
