control.simulate.tergm: Auxiliary for Controlling Temporal ERGM Simulation

Description

Auxiliary function as user interface for fine-tuning TERGM simulation.

Usage

control.simulate.tergm(
  MCMC.burnin.min = NULL,
  MCMC.burnin.max = NULL,
  MCMC.burnin.pval = NULL,
  MCMC.burnin.add = NULL,
  MCMC.prop = NULL,
  MCMC.prop.weights = NULL,
  MCMC.prop.args = NULL,
  MCMC.maxedges = NULL,
  MCMC.maxchanges = NULL,
  term.options = NULL,
  MCMC.packagenames = NULL
)
control.simulate.formula.tergm(
  MCMC.burnin.min = 1000,
  MCMC.burnin.max = 1e+05,
  MCMC.burnin.pval = 0.5,
  MCMC.burnin.add = 1,
  MCMC.prop = ~discord + sparse,
  MCMC.prop.weights = "default",
  MCMC.prop.args = NULL,
  MCMC.maxedges = Inf,
  MCMC.maxchanges = 1e+06,
  term.options = NULL,
  MCMC.packagenames = c()
)

Value

A list with arguments as components.

Arguments

MCMC.burnin.min, MCMC.burnin.max, MCMC.burnin.pval, MCMC.burnin.add

Number of Metropolis-Hastings steps per time step used in simulation. By default, this is determined adaptively by keeping track of increments in the Hamming distance between the transitioned-from network and the network being sampled. Once MCMC.burnin.min steps have elapsed, the increments are tested against 0, and when their average number becomes statistically indistinguishable from 0 (with the p-value being greater than MCMC.burnin.pval), or MCMC.burnin.max steps are proposed, whichever comes first, the simulation is stopped after an additional MCMC.burnin.add times the number of elapsed steps have been taken. (Stopping immediately would bias the sampling.)

To use a fixed number of steps, set MCMC.burnin.min and MCMC.burnin.max to the same value.

MCMC.prop

Hints and/or constraints for selecting and initializing the proposal.

MCMC.prop.weights

Specifies the proposal weighting scheme to be used in the MCMC Metropolis-Hastings algorithm. Possible choices may be determined by calling ergm_proposal_table().

MCMC.prop.args

An alternative, direct way of specifying additional arguments to the proposal.

MCMC.maxedges

The maximum number of edges that may occur during the MCMC sampling. If this number is exceeded at any time, sampling is stopped immediately.

MCMC.maxchanges

Maximum number of changes for which to allocate space.

term.options

A list of additional arguments to be passed to term initializers. See ? term.options.

MCMC.packagenames

Names of packages in which to look for change statistic functions in addition to those autodetected. This argument should not be needed outside of very strange setups.

Details

This function is only used within a call to the simulate() function. See the Usage section in simulate.tergm() for details.
