Statistical Thinking through Media Examples uses real-world
examples from various media to give students an introduction to
fundamentals of statistical thinking. Unlike many standard texts in
the discipline, the book focuses on conceptual understanding-the
meaning behind mathematical calculations rather than the
calculations themselves. The book presents a rigorous introduction
to statistical thinking, the necessary foundation for both the
discipline of statistics and data science. Written in accessible
language, the book begins by discussing the importance of learning
how to assess the quality of research results presented by the
media. This understanding creates an essential context for the
following chapters on questioning study design, including polls and
surveys. The remaining chapters explain the foundational
concepts-probability, reasoning with variation in data, confidence
intervals, hypothesis testing, and linear regression-through media
examples. Students also learn how hypothesis testing can be misused
and manipulated by researchers to provide a desired result. The
third edition features contemporary media examples and related
research findings on a variety of issues, including
hydroxychloroquine and COVID-19, the effectiveness of mask
recommendations, vaccine hesitancy and COVID-19, the inaccuracies
of poll projections in swing states during the 2020 election,
obesity and COVID-19, racial inequality, and climate change.
Statistical Thinking through Media Examples is an ideal primary
textbook for any course that deals with introductory statistics,
particularly those in the health and social sciences, journalism,
and business.
The sixth edition of Meaningful Statistics introduces students to
foundational concepts and demonstrates how statistics are an
integral aspect of their everyday lives-from baseball batting
averages to reports on the median cost of buying a home to the
projected outcomes of an upcoming election. Each chapter begins
with a question and scenario that is then explored through
statistical concepts, demonstrating to students how research and
statistics can help us to answer questions and solve problems. The
opening chapter focuses on the process of collecting data and uses
this information to explore whether multivitamins are a waste of
money. Additional chapters explore linear regression and whether
junk food is harmful to a child's IQ; normal distribution and the
issue of a tie for Olympic downhill gold; confidence intervals and
a simulation of the NBA draft lottery; and more. Students learn
about descriptive measures for populations and samples; probability
and random variables; and sampling distributions, with each concept
corresponding to real-world examples. Closing chapters cover the
testing of hypotheses, tests using the chi-square distribution; and
inferences with two or more populations. For the sixth edition,
exercises and examples have been updated throughout. Designed to
bring key concepts to life, Meaningful Statistics is an ideal
resource for courses in mathematics and statistics.
Flexible Bayesian Regression Modeling is a step-by-step guide to
the Bayesian revolution in regression modeling, for use in advanced
econometric and statistical analysis where datasets are
characterized by complexity, multiplicity, and large sample sizes,
necessitating the need for considerable flexibility in modeling
techniques. It reviews three forms of flexibility: methods which
provide flexibility in their error distribution; methods which
model non-central parts of the distribution (such as quantile
regression); and finally models that allow the mean function to be
flexible (such as spline models). Each chapter discusses the key
aspects of fitting a regression model. R programs accompany the
methods. This book is particularly relevant to non-specialist
practitioners with intermediate mathematical training seeking to
apply Bayesian approaches in economics, biology, finance,
engineering and medicine.

In a world where we are constantly being asked to make decisions
based on incomplete information, facility with basic probability is
an essential skill. This book provides a solid foundation in basic
probability theory designed for intellectually curious readers and
those new to the subject. Through its conversational tone and
careful pacing of mathematical development, the book balances a
charming style with informative discussion. This text will immerse
the reader in a mathematical view of the world, giving them a
glimpse into what attracts mathematicians to the subject in the
first place. Rather than simply writing out and memorizing
formulas, the reader will come out with an understanding of what
those formulas mean, and how and when to use them. Readers will
also encounter settings where probabilistic reasoning does not
apply or where intuition can be misleading. This book establishes
simple principles of counting collections and sequences of
alternatives, and elaborates on these techniques to solve real
world problems both inside and outside the casino. Pair this book
with the HarvardX online course for great videos and interactive

Individual Participant Data Meta-Analysis: A Handbook for
Healthcare Research provides a comprehensive introduction to the
fundamental principles and methods that healthcare researchers need
when considering, conducting or using individual participant data
(IPD) meta-analysis projects. Written and edited by researchers
with substantial experience in the field, the book details key
concepts and practical guidance for each stage of an IPD
meta-analysis project, alongside illustrated examples and summary
learning points. Split into five parts, the book chapters take the
reader through the journey from initiating and planning IPD
projects to obtaining, checking, and meta-analysing IPD, and
appraising and reporting findings. The book initially focuses on
the synthesis of IPD from randomised trials to evaluate treatment
effects, including the evaluation of participant-level effect
modifiers (treatment-covariate interactions). Detailed extension is
then made to specialist topics such as diagnostic test accuracy,
prognostic factors, risk prediction models, and advanced
statistical topics such as multivariate and network meta-analysis,
power calculations, and missing data. Intended for a broad
audience, the book will enable the reader to: Understand the
advantages of the IPD approach and decide when it is needed over a
conventional systematic review Recognise the scope, resources and
challenges of IPD meta-analysis projects Appreciate the importance
of a multi-disciplinary project team and close collaboration with
the original study investigators Understand how to obtain, check,
manage and harmonise IPD from multiple studies Examine risk of bias
(quality) of IPD and minimise potential biases throughout the
project Understand fundamental statistical methods for IPD
meta-analysis, including two-stage and one-stage approaches (and
their differences), and statistical software to implement them
Clearly report and disseminate IPD meta-analyses to inform policy,
practice and future research Critically appraise existing IPD
meta-analysis projects Address specialist topics such as effect
modification, multiple correlated outcomes, multiple treatment
comparisons, non-linear relationships, test accuracy at multiple
thresholds, multiple imputation, and developing and validating
clinical prediction models Detailed examples and case studies are
provided throughout.

Engineering, and Reliability/Quality Engineering. The book also
includes a comprehensive bibliography to assist readers seeking to
delve deeper.
Ranked Set Sampling: 65 Years Improving the Accuracy in Data
Gathering is an advanced survey technique which seeks to improve
the likelihood that collected sample data presents a good
representation of the population and minimizes the costs associated
with obtaining them. The main focus of many agricultural,
ecological and environmental studies is the development of well
designed, cost-effective and efficient sampling designs, giving RSS
techniques a particular place in resolving the disciplinary
problems of economists in application contexts, particularly
experimental economics. This book seeks to place RSS at the heart
of economic study designs.
Finance and insurance companies are facing a wide range of
parametric statistical problems. Statistical experiments generated
by a sample of independent and identically distributed random
variables are frequent and well understood, especially those
consisting of probability measures of an exponential type. However,
the aforementioned applications also offer non-classical
experiments implying observation samples of independent but not
identically distributed random variables or even dependent random
variables. Three examples of such experiments are treated in this
book. First, the Generalized Linear Models are studied. They extend
the standard regression model to non-Gaussian distributions.
Statistical experiments with Markov chains are considered next.
Finally, various statistical experiments generated by fractional
Gaussian noise are also described. In this book, asymptotic
properties of several sequences of estimators are detailed. The
notion of asymptotical efficiency is discussed for the different
statistical experiments considered in order to give the proper
sense of estimation risk. Eighty examples and computations with R
software are given throughout the text.
Nonlinear Time Series Analysis with R provides a practical guide to
emerging empirical techniques allowing practitioners to diagnose
whether highly fluctuating and random appearing data are most
likely driven by random or deterministic dynamic forces. It joins
the chorus of voices recommending 'getting to know your data' as an
essential preliminary evidentiary step in modelling. Time series
are often highly fluctuating with a random appearance. Observed
volatility is commonly attributed to exogenous random shocks to
stable real-world systems. However, breakthroughs in nonlinear
dynamics raise another possibility: highly complex dynamics can
emerge endogenously from astoundingly parsimonious deterministic
nonlinear models. Nonlinear Time Series Analysis (NLTS) is a
collection of empirical tools designed to aid practitioners detect
whether stochastic or deterministic dynamics most likely drive
observed complexity. Practitioners become 'data detectives'
accumulating hard empirical evidence supporting their modelling
approach. This book is targeted to professionals and graduate
students in engineering and the biophysical and social sciences.
Its major objectives are to help non-mathematicians - with limited
knowledge of nonlinear dynamics - to become operational in NLTS;
and in this way to pave the way for NLTS to be adopted in the
conventional empirical toolbox and core coursework of the targeted
disciplines. Consistent with modern trends in university
instruction, the book makes readers active learners with hands-on
computer experiments in R code directing them through NLTS methods
and helping them understand the underlying logic (please see
www.marco.bittelli.com). The computer code is explained in detail
so that readers can adjust it for use in their own work. The book
also provides readers with an explicit framework - condensed from
sound empirical practices recommended in the literature - that
details a step-by-step procedure for applying NLTS in real-world
data diagnostics.
