A model selection approach to analysis of variance and covariance.

13 Jun 2009 An alternative to analysis of variance is a model selection approach where every partition of the treatment means into clusters with equal value is treated as a separate model. The null hypothesis that all treatments are equal corresponds to the ... Read more...

Correlated bivariate continuous and binary outcomes: issues and applications.

13 Jun 2009 Increasingly multiple outcomes are collected in order to characterize treatment effectiveness or to evaluate the impact of large policy initiatives. Often the multiple outcomes are non-commensurate, e.g. measured on different scales. The common ... Read more...

The k-in-a-row up-and-down design, revisited.

13 Jun 2009 The percentile-finding experimental design known variously as 'forced-choice fixed-staircase', 'geometric up-and-down' or 'k-in-a-row' (KR) was introduced by Wetherill four decades ago. To date, KR has been by far the most widely used up-and-down ... Read more...
