#' Test data for Record Linkage
#'
#' These tables contain artificial personal data for the
#' evaluation of Record Linkage procedures. Some records have been duplicated
#' with randomly generated errors. `RLdata500` contains 50 duplicates,
#' `RLdata10000` 1000 duplicates.
#'
#' @format \code{RLdata500} and \code{RLdata10000} are data frames with
#' 500 and 10000 records respectively, and 7 variables:
#' \describe{
#'  \item{fname_c1}{First name, first component}
#'  \item{fname_c2}{First name, second component}
#'  \item{lname_c1}{Last name, first component}
#'  \item{lname_c2}{Last name, second component}
#'  \item{by}{Year of birth}
#'  \item{bm}{Month of birth}
#'  \item{bd}{Day of birth}
#' }
#' `identity.RLdata500` and `identity.RLdata10000` are vectors
#' representing the true record ids of the two data sets. A pair of records
#' are duplicates, if and only if their corresponding values in the
#' identity vector agree.

#' @source
#' Generated with the data generation component of Febrl (Freely Extensible
#' Biomedical Record Linkage), version 0.3
#' <https://sourceforge.net/projects/febrl/>.
#'
#' The following data sources were used (all relate to Germany):
#'
#' * <http://blog.beliebte-vornamen.de/2009/02/prozentuale-anteile-2008/>, a
#'   list of the frequencies of the 20 most popular female names in 2008.
#' * <http://www.beliebte-vornamen.de/760-alle_jahre.htm>, a list of the
#'   100 most popular first names since 1890. The frequencies found in
#'   the source above were extrapolated to fit this list.
#' * <http://www.ahnenforschung-in-stormarn.de/geneal/nachnamen_100.htm>,
#'   a list of the 100 most frequent family names with frequencies.
#'
#' * Age distribution as of Dec 31st, 2008, statistics of Statistisches
#'   Bundesamt Deutschland, taken from the GENESIS database
