Getting numbers is easy; getting numbers you can trust is hard. This practical guide by experimentation leaders at Google, LinkedIn, and Microsoft will teach you how to accelerate innovation using trustworthy online controlled experiments, or A/B tests. Based on practical experiences at companies that each run more than 20,000 controlled experiments a year, the authors share examples, pitfalls, and advice for students and industry professionals getting started with experiments, plus deeper dives into advanced topics for practitioners who want to improve the way they make data-driven decisions. Learn how to • Use the scientific method to evaluate hypotheses using controlled experiments • Define key metrics and ideally an Overall Evaluation Criterion • Test for trustworthiness of the results and alert experimenters to violated assumptions • Build a scalable platform that lowers the marginal cost of experiments close to zero • Avoid pitfalls like carryover effects and Twyman's law • Understand how statistical issues play out in practice.

The essential guide for data scientists and for leaders who must get more from their data science teams The Economist boldly claims that data are now "the world's most valuable resource." But, as Kenett and Redman so richly describe, unlocking that value requires far more than technical excellence. The Real Work of Data Science explores understanding the problems, dealing with quality issues, building trust with decision makers, putting data science teams in the right organizational spots, and helping companies become data-driven. This is the work that spells the difference between a good data scientist and a great one, between a team that makes marginal contributions and one that drives the business, between a company that gains some value from its data and one in which data truly is "the most valuable resource." "These two authors are world-class experts on analytics, data management, and data quality; they've forgotten more about these topics than most of us will ever know. Their book is pragmatic, understandable, and focused on what really counts. If you want to do data science in any capacity, you need to read it." —Thomas H. Davenport, Distinguished Professor, Babson College and Fellow, MIT Initiative on the Digital Economy "I like your book. The chapters address problems that have faced statisticians for generations, updated to reflect today's issues, such as computational Big Data." —Sir David Cox, Warden of Nuffield College and Professor of Statistics, Oxford University "Data science is critical for competitiveness, for good government, for correct decisions. But what is data science? Kenett and Redman give, by far, the best introduction to the subject I have seen anywhere. They address the critical questions of formulating the right problem, collecting the right data, doing the right analyses, making the right decisions, and measuring the actual impact of the decisions. This book should become required reading in statistics and computer science departments, business schools, analytics institutes and, most importantly, by all business managers." —A. Blanton Godfrey, Joseph D. Moore Distinguished University Professor, Wilson College of Textiles, North Carolina State University
L. Ron Hubbard exposed the brutal truth of a psychiatric chemical onslaught, the likes of which this world has never seen. This, then, is the story of 21st century cultural wastage. Also detailed is Mr. Hubbard s clear and understandable solution to all chemical toxins, with the Purification Program and the worldwide network of Narconon rehabilitation centers. Narconon is the by far most successful drug rehabilitation program, with the maximum percentage of those who never revert to drugs again. This volume covers L. Ron Hubbard's development and discoveries, as well as a history of its organizations, that have saved hundreds of thousands of lives by getting them off of drugs permanently.
This all-encompassing compendium for The L. Ron Hubbard Series highlights all he achieved as a humanitarian, educator, administrator, philosopher and artist. It further presents the only complete chronological overview of his life and discoveries. CONTENTS INCLUDE: L. Ron Hubbard: A Profile An Introduction to L.

A sweeping perspective on L. Ron Hubbard, Educator and his deeply illuminating development of "Study Technology", a method of learning and teaching based on full understanding and practical application of any subject. This volume covers the method itself, its development, and some of the more prominent organizations working with it.
The fact is, up to now the mysteries of the mind have not been fully understood and certainly not with any scientific precision. The fields of mental healing have been prone to "best guesses" while depression and anxiety still have no clear answer--until now. A simple, easy technique has been developed which allows you to address a range of undesirable emotions, reactions and attitudes toward life. It is by far the easiest and most enjoyable self betterment technique available and most importantly, it works. In fact, it was originally released in 1951 but is still relevant in today's modern age. Before you begin on your path of self discovery, it's important to gauge your current emotional condition. This next section will show you how. How to Measure Your Potential for Success Contrary to popular belief, your youthful and energetic attitude toward life never actually goes away. Rather, it is buried by the physical and emotional pain and stresses of your past. Each negative incident you run into through life will drive your emotional condition lower, and each success will move it up. When you have too much negativity and not enough success in your past, you wind up deeply depressed and unable to function in life. The events of the past have an affect on your present emotional state. By using the Self Analysis program, you will begin to remove this negative energy. Your outlook and happiness will grow as you unburden past emotional trauma and losses. You also gain a more positive attitude toward yourself and your abilities. Thus, you will get back in control of your life and future, instead of being stuck in the shadows of your past. With the Self Analysis program, there is a simple and effective technique that anyone can use to systematically relieve the negative emotional energy that has built up in your mind and rise up on the chart. The program is composed of self processing. What is Self Processing? The technique we are discussing here is not "positive thinking," brain exercises, meditation or self-hypnosis. You may have tried some of these techniques before, and even achieved some benefit. But they do not get to the source of the problem--often the gains fade and you find yourself in the same place you started. It is possible to desensitize the harmful "charge" from incidents in your past. One way this is done is by moving your attention to pleasurable incidents by using the self processing technique below. Unlike positive affirmations or mantras, your concentration will be in recalling actual incidents in your past. It is remarkably simple to do yet quite powerful. In addition to discharging the negative emotional effects of the past, your personal abilities can also dramatically increase. Imagine being able to finally step out of the shadows of the past and into the vibrant light of the present with sharper senses and renewed vigor for life Begin the Adventure of Self Discovery How does one go about the self processing technique? The full regimen and instructions are contained in the book, Self Analysis by L. Ron Hubbard. L. Ron Hubbard began Self Analysis with these lines: "Self Analysis cannot revive the dead. "Self Analysis will not empty insane asylums or stop war. ... "But Self Analysis will conduct you on the most interesting adventure in your life. The adventure of you." Self Analysis has sold millions of copies in 50 languages across the globe. It starts with a series of short essays written in simple terms to get you to fully understand what it is, how it works and how to use the techniques in the book. Then, there are 12 target areas of your life that the processes cover which you will be able to
