Hello, I am comparing two ROC curves with bootstraping. However, some runs return "p-value = NA," and I have no clue why.
Is this anyhow related to like sample size or no sufficient numbers of bootstraping? I used the default value (i.e. boot.n=2000), and the number of observations are quite big since I am comparing maps (e.g., the largest has more than 9 million observations). It'd would be great if someone could explain why this is happening. With thanks, OK -- View this message in context: http://r.789695.n4.nabble.com/pROC-roc-test-returns-NA-p-value-tp4585795p4585795.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.
