On page 3088, the title of Table I should be
‘Values of θ(o) = P(X<X) − P(X>X)’
On page 3092, the sentence before formula (8): replace (A + r0B) by (r0A + B)
Page 3099, three lines above the sample size table: replace by .
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))’
