This function computes the Deviance Information Criterion from the MCMC object returned by ancThresh.
threshDIC(tree, x, mcmc, burnin=NULL, sequence=NULL, method="pD")phylogenetic tree.
a named vector containing discrete character states; or a matrix containing the tip species, in rows, and probabilities of being in each state, in columns.
list object returned by ancThresh.
number of generations (not samples) to exclude as burn in; if not supplied then 20 percent of generations are excluded.
assumed ordering of the discrete character state. If not supplied and x is a vector then numerical-alphabetical order is assumed; if not supplied and x is a matrix, then the column order of x is used.
method for computing the effective number of parameters (options are "pD" and "pV").
A vector containing the mean deviance and deviance for the parameter means, the effective number of parameters, and the DIC.
