Oh honey I'm searching for love that is true,
But driving through fog is so dang hard to do.
Please paint me a line on the road to your heart,
I'll rev up my pick up and get a clean start.
1.1. Real People can Read This Book
This book explains how to actually do Bayesian data analysis, by real people (like you), for realistic data (like yours). The book starts at the basics, with notions of probability and programming, then progresses to advanced hierarchical models that are used in realistic data analysis. In other words, you do not need to already know statistics and programming. This book is speaking to a first-year graduate student or advanced undergraduate in the social or biological sciences: someone who grew up in Lake Wobegon, mythical being who has the previous training of a nuclear physicist and then decided to learn about Bayesian statistics.
1A popular weekly radio show on National Public Radio, called A Prairie Home Companion, features fictional anecdotes about a small town named Lake Wobegon. The stories, written and orated by Garrison Keillor, always end with the phrase, And that's the news from Lake Wobegon, where all the women are strong, all the men are good looking, and all the children are above average. So, if you grew up there, .
This book provides broad coverage and ease of access. describes the contents in a bit more detail, but here are some highlights. This book covers Bayesian analogues of all the traditional statistical tests that are presented in introductory statistics textbooks, including
-tests, analysis of variance (ANOVA), regression, chi-square tests, and so on. This book also covers crucial issues for
designing research, such as statistical power and methods for determining the sample size needed to achieve a desired research goal. And you don't need to already know statistics to read this book, which starts at the beginning, including introductory chapters about concepts of probability and an entire chapter devoted to Bayes' rule. The important concept of hierarchical modeling is introduced with unique simple examples, and the crucial methods of Markov chain Monte Carlo sampling are explained at length, starting with simple examples that, again, are unique to this book. Computer programs are thoroughly explained throughout the book and are listed in their entirety, so you can use and adapt them to your own needs.
But wait, there's more. As you may have noticed from the beginning of this chapter, the chapters commence with a stanza of elegant and insightful verse composed by a famous poet. The quatrains or, colloquially speaking, country waltz meter. The poems regard conceptual themes of the chapter via allusion from immortal human motifs often expressed by country western song lyrics, all in waltz timing.
2quatrain [noun]: Four lines of verse. (Unless it's written qua train, in which case it's a philosopher comparing something to a locomotive.)
3dactylic [adj.]: A metrical foot in poetry comprising one stressed and two unstressed syllables. (Not to be confused with a pterodactyl, which was a flying dinosaur and which probably sounded nothing like a dactyl unless it fell from the sky and bounced twice: THUMP-bump-bump.)
4tetrameter [noun]: A line of verse containing four metrical feet. (Not to be confused with a quadraped, which has four feet but is averse to lines.)
If you do not find them to be all that funny,
if they leave you wanting back all of your money,
well honey some waltzing's a small price to pay,
