 MultiPhaseTimeRange R Documentation

Phase time range for multiple groups

Description

Computes the shortest interval that satisfies P(PhaseMin < IntervalInf < IntervalSup < PhaseMax | M) = level for each phase

Usage

```MultiPhaseTimeRange(
data,
position_minimum,
position_maximum = position_minimum + 1,
level = 0.95
)
```

Arguments

 `data` Data frame containing the output of the MCMC algorithm. `position_minimum` Numeric vector containing the column number corresponding to the minimum of the events included in each phase. `position_maximum` Numeric vector containing the column number corresponding to the maximum of the phases set in the same order as in `position_minimum`. `level` Probability corresponding to the desired level of confidence.

Details

For each `i`, `MultiPhaseTimeRange()` computes the time range interval for the phase defined by its minimum `position_minimum[i]` and its maximum `position_maximum[i]`. The default value of `position_maximum` corresponds to CSV files exported from ChronoModel software.

Value

A matrix of values containing the level of confidence and the endpoints of the shortest time range associated with the desired `level`. The result is given in calendar years (BC/AD).

Examples

```  # Data extracted from ChronoModel software
data(Phases)
# List of the name of the groups
names(Phases)
# Stipulating position_maximum
MultiPhaseTimeRange(Phases, position_minimum = c(4, 2), position_maximum = c(5, 3))
# In this case, equivalent to
MultiPhaseTimeRange(Phases, position_minimum = c(4, 2))
