Kendall's tau-c
Hello, I can't find a package which calculates Kendall's tau-c. There is the package Kendall, but it only calcuates Kendall's tau-b. Here is the example from ttp://www2.chass.ncsu.edu/garson/pa765/assocordinal.htm. cityriots <- data.frame(citysize=c(1,1,2,2,3,3), riotsize=c(1,2,1,2,1,2), weight=c(4,2,2,3,0,4)) cityriots <- data.frame(lapply(cityriots,function(x) rep(x,cityriots$weight))) xtabs(~ riotsize+citysize,cityriots) tau-c should be .57. Do you have a hint? Best regards Knut Wenzig -- Dipl.-Sozialw....
