Book Description
The Book of R is a comprehensive, beginner-friendly guide to R, the world’s most popular programming language for statistical analysis. Even if you have no programming experience and little more than a grounding in the basics of mathematics, you’ll find everything you need to begin using R effectively for statistical analysis. You’ll start with the basics, like how to handle data and write simple programs, before moving on to more advanced topics, like producing statistical summaries of your data and performing statistical tests and modeling. You’ll even learn how to create impressive data visualizations with R’s basic graphics tools and contributed packages, like ggplot2 and ggvis, as well as interactive 3D visualizations using the rgl package. Dozens of hands-on exercises (with downloadable solutions) take you from theory to practice, as you learn: –The fundamentals of programming in R, including how to write data frames, create functions, and use variables, statements, and loops –Statistical concepts like exploratory data analysis, probabilities, hypothesis tests, and regression modeling, and how to execute them in R –How to access R’s thousands of functions, libraries, and data sets –How to draw valid and useful conclusions from your data –How to create publication-quality graphics of your results Combining detailed explanations with real-world examples and exercises, this book will provide you with a solid understanding of both statistics and the depth of R’s functionality. Make The Book of R your doorway into the growing world of data analysis.

Book Description
Convex optimization problems arise frequently in many different fields. This book provides a comprehensive introduction to the subject, and shows in detail how such problems can be solved numerically with great efficiency. The book begins with the basic elements of convex sets and functions, and then describes various classes of convex optimization problems. Duality and approximation techniques are then covered, as are statistical estimation techniques. Various geometrical problems are then presented, and there is detailed discussion of unconstrained and constrained minimization problems, and interior-point methods. The focus of the book is on recognizing convex optimization problems and then finding the most appropriate technique for solving them. It contains many worked examples and homework exercises and will appeal to students, researchers and practitioners in fields such as engineering, computer science, mathematics, statistics, finance and economics.

The easy way to take charge of your adrenal health Despite their small size, the adrenal glands play an important role in the body, producing numerous hormones that impact our development and growth, affect our ability to deal with stress, and help to regulate kidney function. In Adrenal Fatigue For Dummies, you'll find clear self-evaluations and treatment guidelines that will empower you to take charge of your adrenal health through nutrition, vitamins, herbs, bioidentical adrenal hormone supplementation, and self-care practices. Adrenal fatigue is in essence a "tired out" adrenal gland that is not able to support the body the way that it should. The effects can be far-reaching and affect the quality of one's daily life. It can affect the immune system, cause inflammation, decrease sex drive, and inhibit the ability to get up in the morning. But now there's hope! The 4-1-1 on the structure and function of the adrenal gland Linking inflammation and adrenal fatigue Connecting food allergy and adrenal issues How to test for adrenal fatigue Information on eating patterns for all-day energy and improved concentration Dealing with other medical conditions and adrenal fatigue Relaxation tips to reduce stress Adrenal Fatigue For Dummies helps those suffering from this debilitating illness reclaim their lives by addressing the delicate balance among the adrenal glands—which can make the day-to-day difference between feeling awful and feeling good.

Book Description
Employing a practical, "learn by doing" approach, this first-rate text fosters the development of the skills beyond the pure mathematics needed to set up and manipulate mathematical models. The author draws on a diversity of fields — including science, engineering, and operations research — to provide over 100 reality-based examples. Students learn from the examples by applying mathematical methods to formulate, analyze, and criticize models. Extensive documentation, consisting of over 150 references, supplements the models, encouraging further research on models of particular interest. The lively and accessible text requires only minimal scientific background. Designed for senior college or beginning graduate-level students, it assumes only elementary calculus and basic probability theory for the first part, and ordinary differential equations and continuous probability for the second section. All problems require students to study and create models, encouraging their active participation rather than a mechanical approach. Beyond the classroom, this volume will prove interesting and rewarding to anyone concerned with the development of mathematical models or the application of modeling to problem solving in a wide array of applications.
