Hi all, given this example
#start a<-c(0,70,50,100,70,650,1300,6900,1780,4930,1120,700,190,940, 760,100,300,36270,5610,249680,1760,4040,164890,17230,75140,1870,22380,5890,2430) length(a) b<-c(0,0,10,30,50,440,1000,140,70,90,60,60,20,90,180,30,90, 3220,490,20790,290,740,5350,940,3910,0,640,850,260) length(b) out<-ks.test(log10(a+1),log10(b+1)) # max distance D out$statistic f.a<-ecdf(log10(a+1)) f.b<-ecdf(log10(b+1)) plot(f.a, verticals=TRUE, do.points=FALSE, col="red") plot(f.b, verticals=TRUE, do.points=FALSE, col="green", add=TRUE) #inverse of ecdf a x.a<-get("x", environment(f.a)) y.a<-get("y", environment(f.a)) # inverse of ecdf b x.b<-get("x", environment(f.b)) y.b<-get("y", environment(f.b)) #end I want to plot the max distance between the two ecdf curves as in the above given chart Is that possible and how? Thanks for your help PS: this is an amended version of a previous thread (but no reply followed) that I’ve deleted from Nabble repository because I realised it was not enough clear (now I hope it’s a little better, sorry for that) -- View this message in context: http://r.789695.n4.nabble.com/Kolmogorov-Smirnov-test-and-the-plot-of-max-distance-between-two-ecdf-curves-tp4631437.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.
