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.

This workbook and solutions manual is intended for advanced undergraduate or beginning graduate students as a supplement to a traditional course in numerical mathematics and as preparation for independent research involving numerical mathematics. The solutions manual provides complete MATLAB code and numerical results for each of the exercises in the workbook and will be especially useful for those students without previous MATLAB programming experience. It is also valuable for classroom instructors to help pinpoint the author's intent in each exercise and to provide a model for graders. Upon completion of this material, students will have a working knowledge of MATLAB programming, they will have themselves programmed algorithms encountered in classwork and textbooks, and they will know how to check and verify their own programs against hand calculations and by reference to theoretical results, special polynomial solutions and other specialized solutions. No previous programming experience with MATLAB is necessary.

"The Manga Guide to Statistics" will teach you everything you need to know about this essential discipline, while entertaining you at the same time. With its unique combination of Japanese-style comics called manga and serious educational content, the EduManga format is already a hit in Japan.

In "The Manga Guide to Statistics," our heroine Rui is determined to learn about statistics to impress the dreamy Mr. Igarashi and begs her father for a tutor. Soon she's spending her Saturdays with geeky, bespectacled Mr. Yamamoto, who patiently teaches her all about the fundamentals of statistics: topics like data categorization, averages, graphing, and standard deviation.

After all her studying, Rui is confident in her knowledge of statistics, including complex concepts like probability, coefficients of correlation, hypothesis tests, and tests of independence. But is it enough to impress her dream guy? Or maybe there's someone better, right in front of her?

Reluctant statistics students of all ages will enjoy learning along with Rui in this charming, easy-to-read guide, which uses real-world examples like teen magazine quizzes, bowling games, test scores, and ramen noodle prices. Examples, exercises, and answer keys help you follow along and check your work. An appendix showing how to perform statistics calculations in Microsoft Excel makes it easy to put Rui's lessons into practice.

This EduManga book is a translation from a bestselling series in Japan, co-published with Ohmsha, Ltd. of Tokyo, Japan.

Das sachliche Hauptziel der Wahrscheinlichkeitsrechnung ist die mathematische Erforschung von Massenerscheinungen. In formaler Hin sicht bedeutet das einen erkenntnistheoretisch genugend scharf ab gegrenzten Problemkreis: diejenigen Gesetzmassigkeiten der Erscheinun gen und Vorgange theoretisch zu erfassen, die durch das Massenhafte an ihnen (d. h. durch das Auftreten einer grossen Anzahl von in gewissem Sinne gleichberechtigten Ereignissen, Grossen u. dgl. m. ) in ihren Haupt zugen bedingt sind, so dass daneben die individuelle Beschaffenheit der einzelnen Ingredienten gewissermassen in den Hintergrund tritt. Rein mathematisch fuhrt das endlich zu Infinitesimalbetrachtungen einer spezifischen Gattung, indem die fur eine unendlich grosse Ingredienten anzahl geltenden Grenzgesetze systematisch untersucht und begrundet werden. In diesem Zusammenhang erscheinen die unter dem Namen von "Grenzwertsatzen" bekannten asymptotischen Gesetze der Wahr scheinlichkeitsrechnung keinesfalls als ein isoliertes Nebenstuck dieser Wissenschaft, sondern sie bilden im Gegenteil den wesentlichsten Teil ihrer Problematik. Diese "asymptotische" Wahrscheinlichkeitsrechnung ist als mathe matische Wissenschaft noch ziemlich weit davon entfernt, ein einheit liches Ganzes zu bilden. Vor wenigen Jahren zahlte sie zu ihren Ergeb nissen nur ein paar ganz abgesondert stehender, durch keinen allgemeinen Standpunkt vereinigter Grenzwertsatze. Nur in der allerletzten Zeit konnte sie gewisse neue Aussichtspunkte erringen, die die Hoffnung erwecken, fur dieses theoretisch grundlegende und auch fur die Natur wissenschaften ausserst wichtige Forschungsgebiet in absehbarer Zeit eine einheitliche Theorie zu gewinnen. Es mussen hier einerseits die aus der physikalischen Statistik kommenden, mit der sog."
