sorry, I repost the question again a=c(0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9) b=c(0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1) cor(a,b)= -1
pa=qbinom(a, 1, 0.5) pb=qbinom(b, 1, 0.5) cor(pa,pb)=-0.8 but when pa=qbinom(a,10,0.5) pb=qbinom(b,10,0.5) cor(pa,pb) becomes -1 again -- View this message in context: http://r.789695.n4.nabble.com/qbinom-tp4651460p4651496.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
