Simplex: Simplex Distribution

SimplexR Documentation

Simplex Distribution

Description

These functions provide information about the simplex distribution with location parameter equal to m and shape equal to s: density, cumulative distribution, quantiles, and random generation.

The simplex distribution has density

f(y) = exp(-((y-m)/(m(1-m)))^2/(2y(1-y)s))/sqrt(2 pi s(y(1-y))^3)

where m is the location parameter of the distribution and s is the shape, and 0<y<1.

Usage

dsimplex(y, m, s, log=FALSE)
psimplex(q, m, s)
qsimplex(p, m, s)
rsimplex(n, m, s)

Arguments

y

vector of responses.

q

vector of quantiles.

p

vector of probabilities

n

number of values to generate

m

vector of location parameters.

s

vector of shape parameters.

log

if TRUE, log probabilities are supplied.
