Following this, you'll study market basket analysis, kernel density estimation, principal component analysis, and anomaly detection. You'll be introduced to these methods using code written in R, with further instructions on how to work with, edit, and improve R code. To help you gain a practical understanding, the book also features useful tips on applying these methods to real business problems, including market segmentation and fraud detection. By working through interesting activities, you'll explore data encoders and latent variable models. By the end of this book, you will have a better understanding of different anomaly detection methods, such as outlier detection, Mahalanobis distances, and contextual and collective anomaly detection. What you will learn Implement clustering methods such as k-means, agglomerative, and divisive Write code in R to analyze market segmentation and consumer behavior Estimate distribution and probabilities of different outcomes Implement dimension reduction using principal component analysis Apply anomaly detection methods to identify fraud Design algorithms with R and learn how to edit or improve code Who this book is forApplied Unsupervised Learning with R is designed for business professionals who want to learn about methods to understand their data better, and developers who have an interest in unsupervised learning. Although the book is for beginners, it will be beneficial to have some basic, beginner-level familiarity with R. This includes an understanding of how to open the R console, how to read data, and how to create a loop. To easily understand the concepts of this book, you should also know basic mathematical concepts, including exponents, square roots, means, and medians.

Many professional, high-quality surveys collect data on people's behaviour, experiences, lifestyles and attitudes. The data they produce is more accessible than ever before. This book provides students with a comprehensive introduction to using this data, as well as transactional data and big data sources, in their own research projects. Here you will find all you need to know about locating, accessing, preparing and analysing secondary data, along with step-by-step instructions for using IBM SPSS Statistics. You will learn how to: Create a robust research question and design that suits secondary analysis Locate, access and explore data online Understand data documentation Check and 'clean' secondary data Manage and analyse your data to produce meaningful results Replicate analyses of data in published articles and books Using case studies and video animations to illustrate each step of your research, this book provides you with the quantitative analysis skills you'll need to pass your course, complete your research project and compete in the job market. Exercises throughout the book and on the book's companion website give you an opportunity to practice, check your understanding and work hands on with real data as you're learning.

Discover the story of your data using the essential elements of associations and correlations Key Features Get a comprehensive introduction to associations and correlations Explore multivariate analysis, understand its limitations, and discover the assumptions on which it's based Gain insights into the various ways of preparing your data for analysis and visualization Book DescriptionAssociations and correlations are ways of describing how a pair of variables change together as a result of their connection. By knowing the various available techniques, you can easily and accurately discover and visualize the relationships in your data. This book begins by showing you how to classify your data into the four distinct types that you are likely to have in your dataset. Then, with easy-to-understand examples, you'll learn when to use the various univariate and multivariate statistical tests. You'll also discover what to do when your univariate and multivariate results do not match. As the book progresses, it describes why univariate and multivariate techniques should be used as a tag team, and also introduces you to the techniques of visualizing the story of your data. By the end of the book, you'll know exactly how to select the most appropriate univariate and multivariate tests, and be able to use a single strategic framework to discover the true story of your data. What you will learn Identify a dataset that's fit for analysis using its basic features Understand the importance of associations and correlations Use multivariate and univariate statistical tests to confirm relationships Classify data as qualitative or quantitative and then into the four subtypes Build a visual representation of all the relationships in the dataset Automate associations and correlations with CorrelViz Who this book is forThis is a book for beginners - if you're a novice data analyst or data scientist, then this is a great place to start. Experienced data analysts might also find value in this title, as it will recap the basics and strengthen your understanding of key concepts. This book focuses on introducing the essential elements of association and correlation analysis.

Das vorliegende Buch verdankt seine Entstehung dem Bedurfnis nach einer ubersichtlichen Einleitung in die Wahr scheinlichkeitsrechnung und einer klaren Darstellung ihrer Hauptsatze, welches sich mir aufdrangte, als ich vor langerer Zeit von einem jungen, auch mathematisch gebildeten Philosophen gebeten wurde, ihn in diese Rechnung einzufuhren. Trotz der Wichtigkeit, welche dieser Zweig der Mathematik besitzt, trotz der Bedeutung seiner Anwendungen auch auf rein wissenschaft lichem Gebiete zufolge der auf ihm basierenden Ausgleichungs rechnung von Beobachtungen fehlte es doch an einem Lehr buche, welches eine erste Einfuhrung ermoglichte. Das mit Recht geruhmte Werk von Hag e n: "Grundzuge der W ahr scheinlichkeitsrechnung" enthalt diese Grundzuge nicht, sondern ihren weiteren Ausbau in der Methode der kleinsten Quadrate und deren Anwendungen. Nur die ersten zwanzig Seiten sind den Hauptsatzen der Wahrscheinlichkeitsreclmung gewidmet; diese enthalten aber lediglich einen Abdruck der zehn Principien, welche La Place in seinem "E88ai Philo8ophique SU1' Les P1'O ba bilite8" als die hauptsachlichsten Resultate des Calculs hinstellt. Obwohl sie mit erlauternden Bemerkungen versehen sind, konnen sie doch eine methodische Einleitung nicht er setzen, ja, sie wirken auf den Anfanger durch die Benutzung von nicht definierten Begriffen, wie den der Ursache, sogar verwirrend ein. IV Den erwahnten Mangel einer methodischen Einleitung soll das vorliegende Buchlein ersetzen; dagegen schien es nicht notig, die Anwendungen der entwi'ckelten Principien auf die Ausgleichungsrechnung zu g'eben, weil hieruber vortreffliche Werke in genugender Anzahl existieren, z. B. das erwahnte von Hagen und die grundlegenden Darstellungen von Ga. uss."

This practical guide is designed for students and researchers with an existing knowledge of R who wish to learn how to apply it in an epidemiological context and exploit its versatility. It also serves as a broader introduction to the quantitative aspects of modern practical epidemiology. The standard tools used in epidemiology are described and the practical use of R for these is clearly explained and laid out. R code examples, many with output, are embedded throughout the text. The entire code is also available on the companion website so that readers can reproduce all the results and graphs featured in the book. Epidemiology with R is an advanced textbook suitable for senior undergraduate and graduate students, professional researchers, and practitioners in the fields of human and non-human epidemiology, public health, veterinary science, and biostatistics.
