run.tfr3.mcmc {bayesTFR} | R Documentation |

Runs (or continues running) MCMCs for simulating Phase III total fertility rate, using a Bayesian hierarchical version of an AR(1) model.

`sim.dir` |
Directory with an existing simulation of phase II TFR (see |

`nr.chains` |
Number of MCMC chains to run. |

`iter` |
Number of iterations to run in each chain. In addition to a single value, it can have the value ‘auto’ in which case the function runs for the number of iterations given in the |

`thin` |
Thinning interval between consecutive observations to be stored on disk. |

`replace.output` |
If |

`my.tfr.file` |
File name containing user-specified TFR time series for one or more countries. See description of this argument in |

`buffer.size` |
Buffer size (in number of iterations) for keeping data in the memory. |

`use.extra.countries` |
By default, only countries are used in the MCMCs that were assigned for estimation (i.e. their ‘include_code’ is 2 in the include) dataset and are in phase III at present time (argument |

`mu.prior.range, rho.prior.range, sigma.mu.prior.range, sigma.rho.prior.range, sigma.eps.prior.range` |
Min and max for the prior (uniform) distribution of these paraemters. |

`mu.ini, rho.ini, sigma.mu.ini, sigma.rho.ini, sigma.eps.ini` |
Initial value(s) of the parameters. It can be a single value or an array of the size |

`mu.ini.range, rho.ini.range, sigma.mu.ini.range, sigma.rho.ini.range, sigma.eps.ini.range` |
Min and max for the initial values. |

`seed` |
Seed of the random number generator. If |

`parallel` |
Logical determining if the simulation should run multiple chains in parallel. If it is |

`nr.nodes` |
Relevant only if |

`compression.type` |
One of ‘None’, ‘gz’, ‘xz’, ‘bz’, determining type of a compression of the MCMC files. Important: Do not use this option for a long MCMC simulation as this tends to cause very long run times due to slow reading! |

`auto.conf` |
List containing a configuration for an ‘automatic’ run (see description of argument |

`verbose` |
Logical switching log messages on and off. |

`verbose.iter` |
Integer determining how often (in number of iterations) messages are outputted during the estimation. |

`...` |
Additional parameters to be passed to the function |

`chain.ids` |
Array of chain identifiers that should be resumed. If it is |

The MCMCs are stored in `sim.dir`

in a subdirectory called “phaseIII”. It has exactly the same structure as phase II MCMCs described in `run.tfr.mcmc`

.

An object of class `bayesTFR.mcmc.set`

which is a list with two components:

`meta` |
An object of class |

`mcmc.list` |
A list of objects of class |
