The revised and updated Second Edition includes new subchapters on evolutionary Blackman-Tukey, Lomb-Scargle and Wavelet powerspectral analyses (Chapters – ), statistical analysis of point distributions and digital elevation models (Chapters and ), and a new chapter on the statistical analysis of directional data (Chapter 10). Whereas undergradu- ates participating in a course on data analysis might go through the entire book, the more experienced reader will use only one particular method to solve a specifi c problem. To facilitate the use of this book for the various readers, I outline the concept of the book and the contents.
