Collects a sample of networks and returns the formation and dissolution statistics of each sample

Description

stergm.getMCMCsample is a low-level internal function not intended to be called directly by end users. It collects a sample of networks and returns the formation and dissolution statistics of each sample, along with a toggle matrix of the changes needed from the original network to each in the sample

Usage

1
2
3
stergm.getMCMCsample(nw, model.form, model.diss, model.mon, 
                    MHproposal.form, MHproposal.diss, 
                    eta.form, eta.diss, control, verbose)

Arguments

nw

a network object

model.form

a formation model, as returned by ergm.getmodel

model.diss

a dissolution model, as returned by ergm.getmodel

model.mon
MHproposal.form

a list of parameters needed for MHproposals of the formations

MHproposal.diss

a list of parameters needed for MHproposals of the dissolutions

eta.form
eta.diss
control

list of control paramters, probably from control.stergm

verbose

logical; whether this and other functions should be verbose

Details

This function is normally called inside simulate.stergm to prepare inputs for the C sampling code and return its results

Value

returns the MCMC sample as a list containing:

  • statsmatrix.form: the matrix of sampled statistics for 'model.form' RELATIVE TO INITIAL NETWORK

  • statsmatrix.diss: the matrix of sampled statistics for 'model.form' RELATIVE TO INITIAL NETWORK

  • statsmatrix.mon: the matrix of sampled statistics for 'model.mon' RELATIVE TO INITIAL NETWORK

  • newnetwork : the final network from the sampling process

  • changed : a toggle matrix, where the first column is the timestamp of the toggle and the 2nd and 3rd columns are the head & tail of the toggle; this is only returned if 'control'$changes is not NULL

  • maxchanges : the "MCMC Dyn workspace"; see 'maxchanges' in the input param list
