The construction and analysis of an experimental design, in which there are t2 experimental units for t treatments, are presented. The design is suitable for experiments in which the treatments are applied to experimental units in a sequence over two periods and where an estimate of the treatments x periods interaction is required. Least squares estimators for the various effects are obtained and the analysis of variance of a numerical example is presented to illustrate the application of the results to experimental data.
Biometrics is a scientific journal emphasizing the role of statistics and mathematics in the biological sciences. Its object is to promote and extend the use of mathematical and statistical methods in pure and applied biological sciences by describing developments in these methods and their applications in a form readily assimilable by experimental scientists. JSTOR provides a digital archive of the print version of Biometrics. The electronic version of Biometrics is available at http://www.blackwell-synergy.com/servlet/useragent?func=showIssues&code;=biom. Authorized users may be able to access the full text articles at this site.
The International Biometric Society is an international society for the advancement of biological science through the development of quantitative theories and the application, development and dissemination of effective mathematical and statistical techniques. The Society welcomes as members biologists, mathematicians, statisticians, and others interested in applying similar techniques.
