thanks rui that's what I was looking for
I have another related question: - why of the difference between the max distance D calculated with ks.test() and the max distance D “manually” calculated as in (2)? I guess it has something to do with the fact that KS is obtained with a maximisation that depends on the range of x values not necessarly coincident in the two different approaches ...any thought about this? maxbre -- View this message in context: http://r.789695.n4.nabble.com/Kolmogorov-Smirnov-test-and-the-plot-of-max-distance-between-two-ecdf-curves-tp4631437p4631564.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.
