ACOMMON problem in applied research is the comparison of treat-ments with a control or
standard. Such a situation may arise, for example, when an agronomist tests the effects on …

In the earlier paper, tables were provided enabling up to nine treatments to be compared
with a control with joint confidence coefficient either. 95 or. 99. Tables for both one-sided …

Four pairwise multiple comparison procedures for the case in which the variances in the
groups are unequal were compared by computer simulation: the GH procedure based on …

The efficiency of a standardised inhalation test procedure was studied by examining the
reproducibility of responses to histamine and methacholine. In addition, the responses to the …

In this paper, the role of significance testing in establishing equivalence between treatments
is described. In place of the more customary null hypothesis of no difference between …

The effect of unequal ni on the error rates of six procedures for pair-wise multiple
comparisons beteen k treatment means with homogeneous variances was studied by …

We consider the problem of simultaneously testing k≥ 2 hypotheses on parameters θ1,…,
θk. In a typical application the θ's may be a set of contrasts, for instance, a set of orthogonal …

In this note we shall derive approximations (which are also lower bounds) to the probability
integral of (1) applicable in special cases when p> 2. These results then can be used to …

A multivariate generelization of Stndent's t-distribution is considered. The bivariata case is
treated in detail; exact and asymptotic expressions for the probability integral and an …

The problem of identifying the lowest dose level for which the mean response differs from
that at the zero dose level is considered. A general framework for stepwise testing …
