getMAPS_ClaDS function

Gets the Maximum A Posteriori for each ClaDS parameter

Extract the MAPs (Maximum A Posteriori) for the marginal posterior distributions estimated with fit_ClaDS

getMAPS_ClaDS(sampler, burn = 1/2, thin = 1)

Arguments

• sampler: The output of a fit_ClaDS run.
• burn: Number of iterations to drop in the beginning of the chains.
• thin: Thinning parameter, one iteration out of "thin" is kept to compute the MAPs.

Returns

A vector MAPS containing the MAPs for the marginal posterior distribution for each of the model's parameters.

MAPS[1:4] are the estimated hyperparameters, with MAPS[1] the sigma parameter (new rates stochasticity), MAPS[2] the alpha parameter (new rates trend), MAPS[3] the turnover rate epsilon, and MAPS[4] the initial speciation rate lambda_0.

MAPS[-(1:4)] are the estimated branch-specific speciation rates, given in the same order as the edges of the phylogeny on which the inference was performed.
