Forecasting: principles and practice Welcome to our online textbook on forecasting. This textbook is intended to provide a comprehensive introduction to forecasting methods and to present enough information about each method for readers to be able to use them sensibly. We don’t attempt to give a thorough discussion of the theoretical details behind each method, although the references at the end of each chapter will fill in many of those details. For most sections, we only assume that readers are familiar with algebra, and high school mathematics should be sufficient background. At the end of each chapter we provide a list of “further reading”. We use R throughout the book and we intend students to learn how to forecast with R. It is free and online, making it accessible to a wide audience.It uses R, which is free, open-source, and extremely powerful software.It is continuously updated. Use the table of contents on the right to browse the book. Happy forecasting!

30 game scripts you can write in PHP, Part 1: Creating 10 fundamental scripts Getting started As both a game master/storyteller and a developer, I frequently find myself writing little utilities and scripts to help me when running, planning, and playing games. Sometimes I need a quick idea. Other times, I just need a whole pile of names for Non-Player Characters (NPCs). Occasionally, I need to geek out on numbers, work out some odds, or integrate some word puzzles into a game. Many of these tasks become more manageable with a little bit of script work ahead of time. This article will explore 10 fundamental scripts that can be used in various types of games. We will blaze through these scripts pretty quickly.

Debunking Handbook, The Posted on 27 November 2011 by John Cook The Debunking Handbook, a guide to debunking misinformation, is now freely available to download. Although there is a great deal of psychological research on misinformation, there's no summary of the literature that offers practical guidelines on the most effective ways of reducing the influence of myths. The Debunking Handbook boils the research down into a short, simple summary, intended as a guide for communicators in all areas (not just climate) who encounter misinformation. The Handbook explores the surprising fact that debunking myths can sometimes reinforce the myth in peoples' minds. Communicators need to be aware of the various backfire effects and how to avoid them, such as: It also looks at a key element to successful debunking: providing an alternative explanation. The Authors: John Cook is the Climate Change Communication Fellow for the Global Change Institute at the University of Queensland. Update: Translations
