Download or read book Introduction to Data Science written by Rafael A. Irizarry and published by CRC Press. This book was released on 2019-11-20 with total page 794 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Data Science: Data Analysis and Prediction Algorithms with R introduces concepts and skills that can help you tackle real-world data analysis challenges. It covers concepts from probability, statistical inference, linear regression, and machine learning. It also helps you develop skills such as R programming, data wrangling, data visualization, predictive algorithm building, file organization with UNIX/Linux shell, version control with Git and GitHub, and reproducible document preparation. This book is a textbook for a first course in data science. No previous knowledge of R is necessary, although some experience with programming may be helpful. The book is divided into six parts: R, data visualization, statistics with R, data wrangling, machine learning, and productivity tools. Each part has several chapters meant to be presented as one lecture. The author uses motivating case studies that realistically mimic a data scientist’s experience. He starts by asking specific questions and answers these through data analysis so concepts are learned as a means to answering the questions. Examples of the case studies included are: US murder rates by state, self-reported student heights, trends in world health and economics, the impact of vaccines on infectious disease rates, the financial crisis of 2007-2008, election forecasting, building a baseball team, image processing of hand-written digits, and movie recommendation systems. The statistical concepts used to answer the case study questions are only briefly introduced, so complementing with a probability and statistics textbook is highly recommended for in-depth understanding of these concepts. If you read and understand the chapters and complete the exercises, you will be prepared to learn the more advanced concepts and skills needed to become an expert.
Download or read book Taking stock what we grow together counts written by Caldwell, B., Gichuru, T., Boscolo, M., Vesa, L., Zapata, J., Grouwels, S., Bull, L., Campbell J and published by Food & Agriculture Org.. This book was released on 2021-06-11 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallholder farmers are commonly thought of as farmers who manage two hectares of land or less. By some estimates they represent approximately a quarter of the world’s population, and manage half of the world’s arable land; they generate billions of dollars in forest and timber products. Collectively, smallholders have the transformative potential to achieve sustainable development and respond to climate change at landscape scales. In order to achieve this collective action, smallholders can and do organize themselves into organizations such as associations and cooperatives, i.e. forest and farm producer organizations (FFPOs). Empowering forest and farm producer organizations will be critical to delivering on the Sustainable Development Goals (SDGs) and Nationally Determined Contributions (NDCs) for mitigating climate change as part of the Paris Agreement. This document has three main premises: first, that smallholders’ farms are businesses, and the decisions that smallholders make about their farms are primarily based on their expected return on investments. The second premise is that the business of growing trees on farms can increase family farmers’ economic resilience and improve the net environmental impact of family farming. The third premise is that small farmers’ business of growing trees will be more economically successful if they can organize themselves to achieve scale. What follows from these premises is the purpose of this document: supporting producer organizations to collect information on their tree assets (i.e. trees grown on their farms) for commercial purposes.

Download or read book R For Marketing Research and Analytics written by Chris Chapman and published by Springer. This book was released on 2019-03-28 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2nd edition of R for Marketing Research and Analytics continues to be the best place to learn R for marketing research. This book is a complete introduction to the power of R for marketing research practitioners. The text describes statistical models from a conceptual point of view with a minimal amount of mathematics, presuming only an introductory knowledge of statistics. Hands-on chapters accelerate the learning curve by asking readers to interact with R from the beginning. Core topics include the R language, basic statistics, linear modeling, and data visualization, which is presented throughout as an integral part of analysis. Later chapters cover more advanced topics yet are intended to be approachable for all analysts. These sections examine logistic regression, customer segmentation, hierarchical linear modeling, market basket analysis, structural equation modeling, and conjoint analysis in R. The text uniquely presents Bayesian models with a minimally complex approach, demonstrating and explaining Bayesian methods alongside traditional analyses for analysis of variance, linear models, and metric and choice-based conjoint analysis. With its emphasis on data visualization, model assessment, and development of statistical intuition, this book provides guidance for any analyst looking to develop or improve skills in R for marketing applications. The 2nd edition increases the book’s utility for students and instructors with the inclusion of exercises and classroom slides. At the same time, it retains all of the features that make it a vital resource for practitioners: non-mathematical exposition, examples modeled on real world marketing problems, intuitive guidance on research methods, and immediately applicable code.
