Initialization: netsim Module

This function initializes the main netsim_dat class data object on which data are stored, simulates the initial state of the networks, and simulates disease status and other attributes.

Usage

initialize.net(x, param, init, control, s)

Arguments

x

If control$start == 1, either a fitted network model object of class netest, a clique layer of class netclique, an observed network layer of class netcensus, or a list of such objects. If control$start > 1, an object of class netsim. When multiple networks are used, the node sets (including network size and nodal attributes) are assumed to be the same for all networks.

param

An EpiModel object of class param.net().

init

An EpiModel object of class init.net().

control

An EpiModel object of class control.net().

s

Simulation number. When restarting, every simulation restarts from the first simulation of x, and a warning is raised (for s = 1) if x holds more than one.

Value

A netsim_dat class main data object.

Details

When re-initializing a simulation, the netsim object passed to initialize.net must contain the elements nwparam, epi, run, coef.form, and num.nw. The parameters are taken from param alone, which must hold all the parameters of the model: the ones of x are not used. The internal groups parameter is restored from the run sublist of x.
