Hypotheses can be "one-sided" or "two-sided". Except for the confidence intervals around observations of 0 in count data, I'm not sure what you mean by a "one-sided confidence interval". My uncertainty certainly increases when you talk about such around regression line estimates. -- David Winsemius Alameda, CA, USA ______________________________________________ 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.
