jackknife.EventDate: Jackknife Event Dates

In kairos: Analysis of Chronological Patterns from Archaeological Count Data

Jackknife Event Dates

Description

Generates jackknife estimations of an event date.

Usage

## S4 method for signature 'EventDate'
jackknife(
  object,
  level = 0.95,
  calendar = get_calendar(),
  progress = getOption("kairos.progress"),
  verbose = getOption("kairos.verbose"),
  ...
)

Arguments

object	An EventDate object (typically returned by event()).
level	A length-one numeric vector giving the confidence level.
calendar	An aion::TimeScale object specifying the target calendar (see aion::calendar()). If NULL, rata die are returned.
progress	A logical scalar: should a progress bar be displayed?
verbose	A logical scalar: should R report extra information on progress?
...	Further arguments to be passed to internal methods.

Details

One type/fabric is removed at a time and all statistics are recalculated. In this way, one can assess whether certain type/fabric has a substantial influence on the date estimate.

A three columns data.frame is returned, giving the results of the resampling procedure (jackknifing fabrics) for each assemblage (in rows) with the following columns:

mean

The jackknife mean (event date).

lower

The lower boundary of the confidence interval.

upper

The upper boundary of the confidence interval.

Value

A data.frame.
