init.incidence.matrix.full: Initialization for incidence matrix (full tree)

In PhylogeneticEM: Automatic Shift Detection using a Phylogenetic EM

Initialization for incidence matrix (full tree)

Description

init.incidence.matrix.full initialize the matrix updated in update.incidence.matrix.full for the computation of the incidence matrix of the full tree in incidence.matrix.full.

Usage

init.incidence.matrix.full(phy)

Arguments

phy	Input tree.

Details

The initialized matrix is squared of size ntaxa + Nnode. Each node represent its parental branch. A row corresponding to a tip i is initialized to a vector of zeros, with only entry i equal to one. (Branch ending at tip i is only in the i^th lineage)

Value

Matrix of size ntaxa + Nnode.
