Description Usage Arguments Details Value
A function for summarizing the state of a model after a shift
1 | shiftSummaries(chain, mcmc, pp.cutoff = 0.3, branches = NULL)
|
chain |
A bayouMCMC chain |
mcmc |
A bayou mcmc object |
pp.cutoff |
The threshold posterior probability for shifts to summarize, if 'branches' specified than this is ignored. |
branches |
The specific branches with shifts to summarize, assuming postordered tree |
shiftSummaries summarizes the immediate parameter values after a shift on a particular branch. Parameters are summarized only for the duration that the particular shift exists. Thus, even global parameters will be different for particular shifts.
A list with elements:
pars
= a bayoupars list giving the location of shifts specified;
tree
= The tree;
pred
= Predictor variable matrix;
dat
= A vector of the data;
SE
= A vector of standard errors;
PP
= Posterior probabilities of the specified shifts;
model
= A list specifying the model used;
variables
= The variables summarized;
cladesummaries
= A list providing the medians and densities of the distributions of regression
variables for each shift;
descendents
= A list providing the taxa that belong to each regime
regressions
= A matrix providing the regression coefficients for each regime.
