Summary statistics of a phase

Description

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

Usage

phase_statistics(min_chain, max_chain, level = 0.95, round_to = 0)

Arguments

min_chain	Numeric vector containing the output of the MCMC algorithm for the start of the phase.
max_chain	Numeric vector containing the output of the MCMC algorithm for the end of the phase.
level	Probability corresponding to the level of confidence used for the credible interval and the highest density region.
round_to	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 list with the following components:

statistics

A data frame where the rows correspond to the summary statistics and the columns include: start, the start of the phase in calendar years (BC/AD); end the end of the phase in calendar years (BC/AD); and duration the duration of the phase in years.

level

Probability corresponding to the level of confidence used for the credible interval and the highest density region.

call
