R Documentation

Summary statistics of a phase

Description

Estimation of summary statistics, including the beginning and end of a phase, and the duration of the phase

Usage

PhaseStatistics(
  PhaseMin_chain,
  PhaseMax_chain,
  level = 0.95,
  roundingOfValue = 0
)

Arguments

PhaseMin_chain	Numeric vector containing the output of the MCMC algorithm for the minimum of the dates included in the phase.
PhaseMax_chain	Numeric vector containing the output of the MCMC algorithm for the maximum of the dates included in the phase.
level	Probability corresponding to the level of confidence used for the credible interval and the highest density region.
roundingOfValue	Integer indicating the number of decimal places.

Details

The summary statistics are those given by the MarginalStatistics() function. The time range is given by PhaseTimeRange() function. The duration is computed as follows: duration = maximum - minimum at each iteration of the MCMC output.

Value

A matrix of values corresponding to the summary statistics:

1

Statistics of the minimum of the dates included in the phase

2

Statistics of the maximum of the dates included in the phase

3

Statistics of the duration of the dates included in the phase

The results are given in calendar year (in format BC/AD).
