phase_statistics {ArchaeoPhases} | R Documentation |
Estimation of summary statistics for the beginning, end, and duration of a phase.
phase_statistics(min_chain, max_chain, level = 0.95, round_to = 0)
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. |
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.
A list with the following components:
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.
Probability corresponding to the level of confidence used for the credible interval and the highest density region.
The function call.
