EliminIndx {MultiStatM}

Distinct values selection vector

Description

Eliminates the duplicated/q-plicated elements in a T-vector of multivariate moments and cumulants. Produces the same results as EliminMatr. Note EliminIndx does not provide the same results as unique()

Usage

EliminIndx(d, q)

Arguments

d

dimension of a vector x

q

power of the Kronecker product

Value

A vector of indexes of the distinct elements in the T-vector
