Join the revolution ignited by the ground-breaking R system!Starting with an introduction to R, covering standard regressionmethods, then presenting more advanced topics, this book guidesusers through the practical and powerful tools that the R systemprovides. The emphasis is on hands-on analysis, graphical displayand interpretation of data. The many worked examples, taken fromreal-world research, are accompanied by commentary on what is doneand why. A website provides computer code and data sets, allowingreaders to reproduce all analyses. Updates and solutions toselected exercises are also available. Assuming only basicstatistical knowledge, the book is ideal for research scientists,final-year undergraduate or graduate level students of appliedstatistics, and practising statisticians. It is both for learningand for reference. This revised edition reflects changes in R since2003 and has new material on survival analysis, random coefficientmodels, and the handling of high-dimensional data.

The main theme of this book is recent progress in structure-preserving algorithmsfor solving initial value problems of oscillatory differential equations arising in avariety of research areas， such as astronomy， theoretical physics， electronics， quan-tum mechanics and engineering. It systematically describes the latest advances in thedevelopment of structure-preserving integrators for oscillatory differential equa-tions， such as structure-preserving exponential integrators， functionally fitted energy-preserving integrators， exponential Fourier collocation methods， trigono-metric collocation methods， and symmetric and arbitrarily high-order time-steppingmethods. Most of the material presented here is drawn from the recent literature.Theoretical analysis of the newly developed schemes shows their advantages in thecontext of structure preservation. All the new methods introduced in this book areproven to be highly effective compared with the well-known codes in the scientificliterature. This

A thorough update to the industry standard for designing,developing, and deploying data warehouse and business intelligencesystems The world of data warehousing has changed remarkably since thefirst edition of The Data Warehouse Lifecycle Toolkit waspublished in 1998. In that time, the data warehouse industry hasreached full maturity and acceptance, hardware and software havemade staggering advances, and the techniques promoted in thepremiere edition of this book have been adopted by nearly all datawarehouse vendors and practitioners. In addition, the term"business intelligence" emerged to reflect the mission of the datawarehouse: wrangling the data out of source systems, cleaning it,and delivering it to add value to the business. Ralph Kimball and his colleagues have refined the original setof Lifecycle methods and techniques based on their consulting andtraining experience. The authors understand first-hand that a datawarehousing/business intelligence (DW/BI) system needs to change asfast as its sur
