EZ.SGB {SGB}

Expectations of Z under the SGB distribution

Description

Expectations under Lebesgue and Aitchison measures for the transformed composition Z= C((U/scale)^{shape1}) and C(Z^{1/shape1}), where C(.) is the closure operation.

Usage

EZ.SGB(D, x)

Arguments

x

vector of parameters (shape1,coefi,shape2) where shape1 is the overall shape, coefi is the vector of regression coefficients (see initpar.SGB) and shape2 the vector of D Dirichlet shape parameters

D

number of parts

Value

A matrix with 4 rows and D columns giving on each row the expectation of parts

EZ

E(Z), expectation under the (ordinary) Lebesgue measure,

EAZ

E_A(Z), expectation under the Aitchison measure,

EZa

E(Z^{1/shape1}), expectation under the (ordinary) Lebesgue measure,

EAZa

E_A(Z^{1/shape1}), expectation under the Aitchison measure.
