McmcdbWide-class: MCMC Samples in wide-format

In jrnold/mcmcdb: MCMC sample database classes

Description

Mcmc samples stored as a matrix with (number of chains x number of iterations) rows and (number of flat parameters) columns.

Slots

samples

matrix containing the sample parameter values. This matrix has (number of chains * iterations) rows, and )number of flat parameters) columns.

parameters

McmcdbParameters.

chains

McmcdbChains.

iters

McmcdbIters.

flatpar_chains

McmcdbFlatparChains.

metadata

list with metadata about the samples.

model_data

namedList. The data used in the model.

version

character version of mcmcdb with which the object was created

See Also
