Details

The printed information for RecLinkData objects includes:

• The number of records.

• The number of record pairs.

• If weights have been calculated for this object, a textual histogram of the weight distribution.

Information on "RecLinkResult" objects includes all of the above and the following:

• The number of detected links, non-links and possible links.

• The following error measures, if the true matching status of all record pairs is known: Alpha error (ratio of false links to matches), beta error (ratio of false non-links to non-matches) and accuracy (ratio of correctly classified pairs to the total number of pairs).

• A cross-classified table counting true matching status against classification. The true matching status is represented as logical values, possibly including NA for unknown status. Classification results are represented by:

  "L"

  for links,

  "P"

  for possible links

  "N"

  for non-links
