This tutorial teaches you how to use the statistical programming language R to develop a business case simulation and analysis. It presents a methodology for conducting business case analysis that minimizes decision delay by focusing stakeholders on what matters most and suggests pathways for minimizing the risk in strategic and capital allocation decisions. Business case analysis, often conducted in spreadsheets, exposes decision makers to additional risks that arise just from the use of the spreadsheet environment. R has become one of the most widely used tools for reproducible quantitative analysis, and analysts fluent in this language are in high demand. The R language, traditionally used for statistical analysis, provides a more explicit, flexible, and extensible environment than spreadsheets for conducting business case analysis. The main tutorial follows the case in which a chemical manufacturing company considers constructing a chemical reactor and production facility to bring a new compound to market. There are numerous uncertainties and risks involved, including the possibility that a competitor brings a similar product online. The company must determine the value of making the decision to move forward and where they might prioritize their attention to make a more informed and robust decision. While the example used is a chemical company, the analysis structure it presents can be applied to just about any business decision, from IT projects to new product development to commercial real estate. The supporting tutorials include the perspective of the founder of a professional service firm who wants to grow his business and a member of a strategic planning group in a biomedical device company who wants to know how much to budget in order to refine the quality of information about critical uncertainties that might affect the value of a chosen product development pathway. What You'll LearnSet up a business case abstraction in an influence diagram to communicate the essence of the problem to other stakeholdersModel the inherent uncertainties in the problem with Monte Carlo simulation using the R languageCommunicate the results graphicallyDraw appropriate insights from the resultsDevelop creative decision strategies for thorough opportunity cost analysisCalculate the value of information on critical uncertainties between competing decision strategies to set the budget for deeper data analysisConstruct appropriate information to satisfy the parameters for the Monte Carlo simulation when little or no empirical data are available Who This Book Is For Financial analysts, data practitioners, and risk/business professionals; also appropriate for graduate level finance, business, or data science students

Get started using Python in data analysis with this compact practical guide. This book includes three exercises and a case study on getting data in and out of Python code in the right format. Learn Data Analysis with Python also helps you discover meaning in the data using analysis and shows you how to visualize it.  Each lesson is, as much as possible, self-contained to allow you to dip in and out of the examples as your needs dictate. If you are already using Python for data analysis, you will find a number of things that you wish you knew how to do in Python. You can then take these techniques and apply them directly to your own projects.If you aren't using Python for data analysis, this book takes you through the basics at the beginning to give you a solid foundation in the topic. As you work your way through the book you will have a better of idea of how to use Python for data analysis when you are finished.What You Will LearnGet data into and out of Python codePrepare the data and its formatFind the meaning of the dataVisualize the data using iPythonWho This Book Is For Those who want to learn data analysis using Python. Some experience with Python is recommended but not required, as is some prior experience with data analysis or data science.

Welcome Welcome to Beginning XSLT, a comprehensive introduction to the Extensible Stylesheet Language Transformations. Who is this Book For? This book introduces those with a little knowledge of markup languages (HTML, XML, etc.) to the exciting world of XSLT. No prior programming knowledge is assumed or needed. This is a beginning book, so we will aim to teach you everything you need to know from scratch. This book will be equally beneficial to designers and programmers alike. What's Covered in this Book This book is divided into two parts. The first part introduces XML and XSL T bit by bit, gradually demonstrating the techniques that you need to generate HTML (and other formats) from XML. The second part pulls the theory together by looking at some of the other things that you can do with XSLT, including generating formats other than HTML, pulling information out of a variety of XML formats, and validating XML.

Information technologists are increasingly being made part of global teams, and are confronting the challenges of communicating across a variety of linguistic and cultural boundaries. This book helps you know what to say, what not to say, and even where to sit in meetings and in social situations.The Tech Professional's Guide to Communicating in a Global Workplace shows you how to effectively communicate across a variety of different cultures within and across organizations. You will become aware of cultural differences from one country or region to another, between various groups at the local level, and across groups such as developers to DBAs, IT staff to business people, women to men, people approaching retirement to people coming into the organization fresh out of college, and more. The author provides her personal experiences and shares anecdotes as well as lessons learned, key takeaways, and references for further reading. Whether it is face to face, over the phone, via email or instant messenger, or in a presentation, meeting, or report, the ability to communicate effectively is critical.What You'll LearnConcisely communicate with the right audience in the right wayWrite emails that are understood and get the results you wantImprove personal reputation as an effective communicatorCommunicate across cultural boundaries without offendingPresent the desired impression in business situationsGrow professionally by adjusting your communication styleWho This Book Is ForProgrammers and system administrators, including database administrators

Use ASP.NET Core 2 to create durable and cross-platform web APIs through a series of applied, practical scenarios. Examples in this book help you build APIs that are fast and scalable. You'll progress from the basics of the framework through to solving the complex problems encountered in implementing secure RESTful services. The book is packed full of examples showing how Microsoft's ground-up rewrite of ASP.NET Core 2 enables native cross-platform applications that are fast and modular, allowing your cloud-ready server applications to scale as your business grows. Major topics covered in the book include the fundamentals and core concepts of ASP.NET Core 2.
