This first volume in the series is devoted to the area of analysis of variance (ANOVA), which was developed by R.A. Fischer and others, and has emerged as a very important branch of statistics. The most useful techniques in univariate and multivariate ANOVA are covered in this volume. The chapters are written by prominent workers in the field for persons who are not specialists on the topic. The volume is of value to the whole statistics community, as well as to scientists in other disciplines who are interested in statistical methodology. The volume is dedicated to the memory of the late Henry Scheffé.
