Dieses Buch ist als Einfuhrung in die Statistik gedacht. Die dargelegten Methoden und Gedankengange sind aus den Statistik- vorlesungen fur Volks- und Betriebswirtschafter hervorgegangen, die ich seit rund einem Jahrzehnt an der Universitat in Freiburg/Schweiz gehalten habe. Das Buch richtet sich deshalb vor allem an Volks- und Betriebs- wirtschafter. Mit Rucksicht auf diesen Leserkreis wurden die notwendigen mathematischen Ableitungen moeglichst luckenlos durchgefuhrt, damit auch Leser, die in der Mathematik weniger bewan ert sind, den Darlegungen folgen und mathematisch anspruchsvollere Lehrbucher der Statistik mit mehr Gewinn lesen koennen. Meine Erfahrung hat gezeigt, dass diese Ableitungen fur das bessere Verstandnis der einzelnen Methoden und deren Grenzen unbedingt erforderlich sind. Der mathematisch geschulte Leser moege deshalb diese mathematische Weitschweifigkeit verzeihen. Das vorliegende Buch durfte deshalb zwischen den elementaren Statistik- buchern und den sehr anspruchsvollen Lehrbuchern der mathematischen Statistik seinen Platz haben. Im Anschluss an dieses Buch sind weitere Darstellungen -uber die Stichprobentheorie, die Versuchsplanung, die statistischen Testverfahren und die Zeitreihenanalyse geplant. Des weiteren wird auch das Verhaltnis zwischen Statistik, Operations Research, OEkonoemetrie und Datenverarbei- tung behandelt werden. Dem Verlag sei an dieser Stelle fur sein Verstandnis und seine her- vorragende Arbeit gedankt. Sollte diesem Buch Erfolg beschieden sein, so ist er weitgehend auf die sorgfaltige Arbeit des Verlags zuruck- zufuhren. Freiburg/Schweiz, Februar 1970 Ernst P. Billeter Inhaltsverzeichnis 1.

Build a strong foundation in SAS data warehousing by understanding data transformation code and policy, data stewardship and management, interconnectivity between SAS and other warehousing products, and print and web reporting Key Features Understand how to use SAS macros for standardizing extract, transform, and load (ETL) protocols Develop and use data curation files for effective warehouse management Learn how to develop and manage ETL, policies, and print and web reports that meet user needs Book DescriptionSAS is used for various functions in the development and maintenance of data warehouses, thanks to its reputation of being able to handle 'big data'. This book will help you learn the pros and cons of storing data in SAS. As you progress, you'll understand how to document and design extract-transform-load (ETL) protocols for SAS processes. Later, you'll focus on how the use of SAS arrays and macros can help standardize ETL. The book will also help you examine approaches for serving up data using SAS and explore how connecting SAS to other systems can enhance the data warehouse user's experience. By the end of this data management book, you will have a fundamental understanding of the roles SAS can play in a warehouse environment, and be able to choose wisely when designing your data warehousing processes involving SAS. What you will learn Develop efficient ways to manage data input/output (I/O) in SAS Create and manage extract, transform, and load (ETL) code in SAS Standardize ETL through macro variables, macros, and arrays Identify data warehouse users and ensure their needs are met Design crosswalk and other variables to serve analyst needs Maintain data curation files to improve communication and management Use the output delivery system (ODS) for print and web reporting Connect other products to SAS to optimize storage and reporting Who this book is forThis book is for data architects, managers leading data projects, and programmers or developers using SAS who want to effectively maintain a data lake, data mart, or data warehouse.

The text is for instructors who want to use MATLAB to teach introductory programming concepts. Since many students struggle with applying the concepts that underlie good programming practice, " Learning to Program with MATLAB: Building GUI Tools" was designed upon the observation that student learning is enhanced if the students themselves build the GUI (graphical user interface) tool, construct the computational model, implement the visualization of results, and design the GUI. This text teaches the core concepts of computer programming--arrays, loops, functions, and basic data structures--using MATLAB. The chapter sequence covers text-based programs, then programs that produce graphics, building up to an emphasis on GUI tools. This progression unleashes the real power of MATLAB--creating visual expressions of the underlying mathematics of a problem or design.

This engaging and clearly written textbook/reference provides a must-have introduction to the rapidly emerging interdisciplinary field of data science. It focuses on the principles fundamental to becoming a good data scientist and the key skills needed to build systems for collecting, analyzing, and interpreting data. The Data Science Design Manual is a source of practical insights that highlights what really matters in analyzing data, and provides an intuitive understanding of how these core concepts can be used. The book does not emphasize any particular programming language or suite of data-analysis tools, focusing instead on high-level discussion of important design principles. This easy-to-read text ideally serves the needs of undergraduate and early graduate students embarking on an "Introduction to Data Science" course. It reveals how this discipline sits at the intersection of statistics, computer science, and machine learning, with a distinct heft and character of its own. Practitioners in these and related fields will find this book perfect for self-study as well. Additional learning tools: Contains "War Stories," offering perspectives on how data science applies in the real world Includes "Homework Problems," providing a wide range of exercises and projects for self-study Provides a complete set of lecture slides and online video lectures at www.data-manual.com Provides "Take-Home Lessons," emphasizing the big-picture concepts to learn from each chapter Recommends exciting "Kaggle Challenges" from the online platform Kaggle Highlights "False Starts," revealing the subtle reasons why certain approaches fail Offers examples taken from the data science television show "The Quant Shop" (www.quant-shop.com)
