Description

compute.transition.matrix is a function to compute the transition matrix of a multiplex heterogeneous network provided as a MultiplexHet object.

Usage

1
compute.transition.matrix(x,lambda = 0.5, delta1=0.5, delta2=0.5)

Arguments

x

A MultiplexHet object describing a multiplex and heterogeneous network generated by the function create.multiplexHet.

lambda

A numeric value between 0 and 1. It sets the probability of jumping within a network or change to the other network of the heterogeneous system. It is set by default to 0.5. See more details below.

delta1

A numeric value between 0 and 1. It sets the probability of performing inter-layer versus intra-layer transitions in the first multiplex. It is set by default to 0.5. See more details below.

delta2

A numeric value between 0 and 1. It sets the probability of performing inter-layer versus intra-layer transitions in the second multiplex. It is set by default to 0.5. See more details below.

Details

We clarify the role of the different parameters in this point:

Value

A square sparse transition matrix created with the Matrix package. It is the transition matrix for the Random Walk with Restart on Multiplex and Heterogeneous networks algorithm.
