> help("epiWeights")
For more details about the weights method, refer to P. Contiero et al. The Epilink record linkage software.
Methods Inf Med., 44(1):66–71, 2005.
The mechanism of invoking and finally generating the results is very similar to how we did it using emWeights:
library(RecordLinkage)data("RLdata500")# weight calculationrec.pairs <- compare.dedup(RLdata500 ,blockfld = list(1, 5:7) ,strcmp = c(2,3,4) ,strcmpfun = levenshteinSim)pairs.weights <- epiWeights(rec.pairs)hist(pairs.weights$Wdata)
One again, the distribution is similar to our histogram from the emWeights method. Let's ...
