Extract peripheral information from runjags objects
Objects of class 'runjags' are produced by
autorun.jags, and contain the MCMC chains as well as all information required to extend the simulation. This function allows specific information to be extracted from these functions. For other utility methods for the runjags class, see
an object of class runjags.
the information contained in the runjags object to be extracted. See the details section for the available options.
option to re-draw new deviance/DIC/PED etc samples from the model (using
additional options to be passed to
The supported options for the 'what' argument are as follows:
crosscorr - the cross-correlation matrix
summary - the same as the summary method for runjags object
model - the model
data - the data
end.state - the model state at the last iteration (or initial values for non-updated models) which will be used to start an extended simulation
samplers - a matrix giving the sampler used for stochastic nodes (not available for all models)
stochastic - a logical vector of length equal to the number of variables indicating which variables are stochastic, with NA values for variables that are stochastic in one chain but not others - the return value of this can be passed to the 'vars' argument for combine.mcmc etc functions
dic - the DIC, as returned by
dic - the PED, as returned by
sum.deviance - the sum of the mean estimated deviance for each stochastic variable
sum.pd - the sum of the mean estimated pD for each stochastic variable
sum.popt - the sum of the mean estimated pOpt for each stochastic variable
mean.deviance - the mean estimated pD for each stochastic variable
mean.pd - the mean estimated pD for each stochastic variable
mean.popt - the mean estimated pOpt for each stochastic variable
full.deviance - the sum of the model deviance at each iteration (for each chain)
full.pd - the sum of the estimated pD at each iteration
Note that for the deviance/DIC related parameters, these will be extracted from the available information if possible, or otherwise re-sampled.
