Zusammenfassung: Learn the art and science of predictive analytics - techniques that get results Predictive analytics is what translates big data into meaningful, usable business information. Written by a leading expert in the field, this guide examines the science of the underlying algorithms as well as the principles and best practices that govern the art of predictive analytics. It clearly explains the theory behind predictive analytics, teaches the methods, principles, and techniques for conducting predictive analytics projects, and offers tips and tricks that are essential for successful predictive modeling. Hands-on examples and case studies are included. The ability to successfully apply predictive analytics enables businesses to effectively interpret big data; essential for competition today This guide teaches not only the principles of predictive analytics, but also how to apply them to achieve real, pragmatic solutions Explains methods, principles, and techniques for conducting predictive analytics projects from start to finish Illustrates each technique with hands-on examples and includes as series of in-depth case studies that apply predictive analytics to common business scenarios A companion website provides all the data sets used to generate the examples as well as a free trial version of software Applied Predictive Analytics arms data and business analysts and business managers with the tools they need to interpret and capitalize on big data.Zusammenfassung: Cover -- Title Page -- Copyright -- Contents -- Chapter 1 Overview of Predictive Analytics -- What Is Analytics? -- What Is Predictive Analytics? -- Supervised vs. Unsupervised Learning -- Parametric vs. Non-Parametric Models -- Business Intelligence -- Predictive Analytics vs. Business Intelligence -- Do Predictive Models Just State the Obvious? -- Similarities between Business Intelligence and Predictive Analytics -- Predictive Analytics vs. Statistics -- Statistics and Analytics -- Predictive Analytics and Statistics Contrasted -- Predictive Analytics vs. Data Mining -- Who Uses Predictive Analytics? -- Challenges in Using Predictive Analytics -- Obstacles in Management -- Obstacles with Data -- Obstacles with Modeling -- Obstacles in Deployment -- What Educational Background Is Needed to Become a Predictive Modeler? -- Chapter 2 Setting Up the Problem -- Predictive Analytics Processing Steps: CRISP-DM -- Business Understanding -- The Three-Legged Stool -- Business Objectives -- Defining Data for Predictive Modeling -- Defining the Columns as Measures -- Defining the Unit of Analysis -- Which Unit of Analysis? -- Defining the Target Variable -- Temporal Considerations for Target Variable -- Defining Measures of Success for Predictive Models -- Success Criteria for Classification -- Success Criteria for Estimation -- Other Customized Success Criteria -- Doing Predictive Modeling Out of Order -- Building Models First -- Early Model Deployment -- Case Study: Recovering Lapsed Donors -- Overview -- Business Objectives -- Data for the Competition -- The Target Variables -- Modeling Objectives -- Model Selection and Evaluation Criteria -- Model Deployment -- Case Study: Fraud Detection -- Overview -- Business Objectives -- Data for the Project -- The Target Variables -- Modeling Objectives -- Model Selection and Evaluation Criteria.PPN: PPN: 1657629198Package identifier: Produktsigel: ZDB-38-EBR | ZDB-89-EBL | ZDB-26-MYL | ZDB-30-PQE | ZDB-30-PQE | ZDB-30-PAD | ZDB-30-PBE | BSZ-30-PQE-S2NUFH-owned
