WebThe adaptive design aims to learn from the accumulated data and apply what is learned as quickly as possible. Therefore, adaptability is a design to enhance the test, rather than a remedy for inadequate planning. Bayesian statistics is a theory based on the Bayesian probability interpretation of the statistical field. Webkernel machines, and QTL mapping. Focusing on design, statistical inference, and data analysis from a Bayesian perspective, this volume explores statistical challenges in bioinformatics data analysis and modeling and offers solutions to these problems. It encourages readers to draw on the evolving technologies and promote statistical
