In kosukeimai/fastLink: Fast Probabilistic Record Linkage with Missing Data

gammaCKpar

Description

Field comparisons for string variables. Three possible agreement patterns are considered: 0 total disagreement, 1 partial agreement, 2 agreement. The distance between strings is calculated using a Jaro-Winkler distance.

Usage

gammaCKpar(matAp, matBp, n.cores, cut.a, cut.p, method, w)

Arguments

matAp	vector storing the comparison field in data set 1
matBp	vector storing the comparison field in data set 2
n.cores	Number of cores to parallelize over. Default is NULL.
cut.a	Lower bound for full match, ranging between 0 and 1. Default is 0.92
cut.p	Lower bound for partial match, ranging between 0 and 1. Default is 0.88
method	String distance method, options are: "jw" Jaro-Winkler (Default), "dl" Damerau-Levenshtein, "jaro" Jaro, and "lv" Edit
w	Parameter that describes the importance of the first characters of a string (only needed if method = "jw"). Default is .10

Value

gammaCKpar returns a list with the indices corresponding to each matching pattern, which can be fed directly into tableCounts and matchesLink.
