The list does not assist with homework problems. If this is not a class assignment, you should be more specific about what you have tried and provide a reproducible example (a sample of the real data or some made-up data that has the same columns and data types). In the meantime you could also try the following R command:

You can also use ?glm with a binomial link, in which case you should recode type as white/not white. Hope this helps, Rui Barradas , which statistic method should use to prove the trend relationship between them, for example, the older has more probability of white hair type? Are there any existed R package to figure out this situation? > > > > Thank you. > > > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see > 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. > ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
