resolve_data

grouped_data

The maximum length of the scanning period.
Can be an integer giving the number of days, the result
of a call to function <code><a rd-options="base" href="/link/difftime?package=migrbc&version=2.0.9&to=base" data-mini-rdoc="base::difftime">difftime</a></code>, or an object of
class <code><a rd-options="lubridate:Duration-class" href="/link/Duration?package=migrbc&version=2.0.9&to=lubridate%3ADuration-class" data-mini-rdoc="lubridate:Duration-class::Duration">Duration</a></code>.

window_size

The length of the yearly test period.
Can be an integer giving the number of days, the result
of a call to function <code><a rd-options="base" href="/link/difftime?package=migrbc&version=2.0.9&to=base" data-mini-rdoc="base::difftime">difftime</a></code>, or an object of
class <code><a rd-options="lubridate:Duration-class" href="/link/Duration?package=migrbc&version=2.0.9&to=lubridate%3ADuration-class" data-mini-rdoc="lubridate:Duration-class::Duration">Duration</a></code>.

threshold_year

Optional, if it is TRUE, run on parallel.

parallel

if <code>parallel</code> set to TRUE, this will specify
the number of computer cores required.

n_core

Optional, if it is TRUE, the returned 
result of <code>error_data</code> will contain two extra columns
 <code>error_code</code> and <code>error_message</code>.

include_error_columns

if set to TRUE then all children that have been 
forked by this function will be killed (by sending SIGTERM) before
this function returns. Under normal circumstances mclapply waits
for the children to deliver results, so this option usually has 
only effect when mclapply is interrupted. If set to FALSE then 
child processes are collected, but not forcefully terminated.
As a special case this argument can be set to the number of the
signal that should be used to kill the children instead of SIGTERM.

mc.cleanup

This function is the key function to do the rules 
 based classification.

Provides mechanisms for classifying border crossings using a rules-based methodology. The goal of performing this type of classification is to identify any potential long-term migrants. A long-term migration is defined as a border crossing involving a change in residence status. A border crossing counts as a long-term migration to/from a country if it entails a change from non-residence to residence / residence to non-residence. The rules-based classification that used to determine a long-term migration is defined by a threshold duration and a test duration, alternatively named window size. Under a 12/16 rule, for instance, the threshold duration is 12 months and the test duration (window size) is 16 months. With a 9/12 rule, the threshold duration is 9 months and the test duration (window size) is 12 months. For more information about the methodology applied, please visit Stats NZ (2020) <https://www.stats.govt.nz/methods/defining-migrants-using-travel-histories-and-the-1216-month-rule>.
