MultiPhasesTransition {ArchaeoPhases} R Documentation

## Transition range for a succession of groups (for groups in temporal order constraint)

### Description

Finds, if it exists, the shortest interval that satisfies P(TransitionRangeInf < Phase1Max < Phase2Min < TransitionRangeSup | M) = level

### Usage

```MultiPhasesTransition(
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 group. `position_maximum` Numeric vector containing the column number corresponding to the end of the groups set in the same order as in codeposition_minimum. `level` Probability corresponding to the level of confidence.

### Details

For each `i`, `MultiPhasesTransition()` computes the transition 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 transition interval for each pair of successive groups. 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
MultiPhasesTransition(Phases, position_minimum = c(4, 2), position_maximum = c(5, 3))
# In this case, equivalent to
MultiPhasesTransition(Phases, position_minimum = c(4, 2))
