Errata

This article corrects:

  1. A rank-based sample size method for multiple outcomes in clinical trials Volume 27, Issue 16, 3084–3104, Article first published online: 14 January 2008

  • On page 3088, the title of Table I should be

  • ‘Values of θ(o) = P(Xmath image<Xmath image) − P(Xmath image>Xmath image)’

  • On page 3092, the sentence before formula (8): replace (A + r0B) by (r0A + B)

  • Page 3099, three lines above the sample size table: replace equation image by equation image.

  • Page 3099, in the second row of the sample size table: replace ‘Sample size per group’ by ‘total sample size N

  • Page 3103, Appendix C1.1: the code ‘Z<- sum(x$theta)*sqrt(N)/2/sum(x$Sigma)’ should be replaced by ‘Z <- sum(x$theta)*sqrt(N)/2/sqrt(sum(x$Sigma))’

We thank Drs B. Tilley and L. Sheng who have kindly made these observations.
