Welcome to the Multitiered experiments web site.

(Established 2001)

The site underwent a major update in January 2018 to bring it into line with more recent publications.

What has changed?

What makes multitiered experiments different?

The site aims to provide an introduction to the design and analysis of multitiered experiments, an overview of the literature on them and some unpublished material. This includes the mixed-model analysis of designed experiments where the allocation is used in specifying the terms to include in the model.

The site is based on the joint work of Chris Brien, Rosemary Bailey, Ray Correll, Bronwyn Harch, Roger Payne and Clarice Demétrio.

The copies of slides for talks by these authors on work related to this site see Research > Slides for talks in the menu below the picture.
