The burgeoning field of data analysis is expanding at an incredible
pace due to the proliferation of data collection in almost every
area of science. The enormous data sets now routinely encountered
in the sciences provide an incentive to develop mathematical
techniques and computational algorithms that help synthesize,
interpret and give meaning to the data in the context of its
scientific setting. A specific aim of this book is to integrate
standard scientific computing methods with data analysis. By doing
so, it brings together, in a self-consistent fashion, the key ideas
from: * statistics, * time-frequency analysis, and *
low-dimensional reductions The blend of these ideas provides
meaningful insight into the data sets one is faced with in every
scientific subject today, including those generated from complex
dynamical systems. This is a particularly exciting field and much
of the final part of the book is driven by intuitive examples from
it, showing how the three areas can be used in combination to give
critical insight into the fundamental workings of various problems.
Data-Driven Modeling and Scientific Computation is a survey of
practical numerical solution techniques for ordinary and partial
differential equations as well as algorithms for data manipulation
and analysis. Emphasis is on the implementation of numerical
schemes to practical problems in the engineering, biological and
physical sciences. An accessible introductory-to-advanced text,
this book fully integrates MATLAB and its versatile and high-level
programming functionality, while bringing together computational
and data skills for both undergraduate and graduate students in
scientific computing.
A new and important contribution to the re-emergent field of
comparative anthropology, this book argues that comparative
ethnographic methods are essential for more contextually
sophisticated accounts of a number of pressing human concerns
today. The book includes expert accounts from an international team
of scholars, showing how these methods can be used to illuminate
important theoretical and practical projects. Illustrated with
examples of successful inter-disciplinary projects, it highlights
the challenges, benefits, and innovative strategies involved in
working collaboratively across disciplines. Through its focus on
practical methodological and logistical accounts, it will be of
value to both seasoned researchers who seek practical models for
conducting their own cutting-edge comparative research, and to
teachers and students who are looking for first-person accounts of
comparative ethnographic research.
Dirty data is a problem that costs businesses thousands, if not
millions, every year. In organisations large and small across the
globe you will hear talk of data quality issues. What you will
rarely hear about is the consequences or how to fix it. Between the
Spreadsheets: Classifying and Fixing Dirty Data draws on
classification expert Susan Walsh's decade of experience in data
classification to present a fool-proof method for cleaning and
classifying your data. The book covers everything from the very
basics of data classification to normalisation and taxonomies, and
presents the author's proven COAT methodology, helping ensure an
organisation's data is Consistent, Organised, Accurate and
Trustworthy. A series of data horror stories outlines what can go
wrong in managing data, and if it does, how it can be fixed. After
reading this book, regardless of your level of experience, not only
will you be able to work with your data more efficiently, but you
will also understand the impact the work you do with it has, and
how it affects the rest of the organisation. Written in an engaging
and highly practical manner, Between the Spreadsheets gives readers
of all levels a deep understanding of the dangers of dirty data and
the confidence and skills to work more efficiently and effectively
with it.
This publication presents a case study in East Java, Indonesia,
about ADB's collaboration with local governments and other
stakeholders in monitoring, implementing, raising awareness, and
advocating for the Sustainable Development Goals (SDGs). The SDGs
set global, big-picture targets that nations have committed to
attaining. However, unless action is taken at the local level,
these targets can never be reached. The case study on Lumajang and
Pacitan district demonstrate how ADB has been helping to make data
available and accessible in a visually attractive and
easy-to-understand way for different local stakeholders, thereby
contributing to localizing SDGs.

We think we know bullshit when we hear it, but do we?
Two science professors give us the tools to dismantle misinformation and think clearly in a world of fake news and bad data
Politicians are unconstrained by facts. Science is conducted by press release. Start-up culture elevates hype to high art. The world is awash in bullshit, and we're drowning in it.
Based on a popular course at the University of Washington, this book gives us the tools to see through the obfuscations, deliberate and careless, that dominate every realm of our lives. In this lively, provocative guide, biologist Carl Bergstrom and data scientist Jevin West show that calling out nonsense is crucial to a properly functioning social group, whether it be a circle of friends, a community of researchers, or the citizens of a nation.
Through six rules of thumb, they help us to recognize when numbers are being manipulated, to cut through the crap wherever we encounter it - even within ourselves - and learn how to give the real facts to a crystal-loving friend or climate change denier uncle.
Calling Bullshit is an indispensable handbook to the art of scepticism.
Probability for Data Scientists provides students with a
mathematically sound yet accessible introduction to the theory and
applications of probability. Students learn how probability theory
supports statistics, data science, and machine learning theory by
enabling scientists to move beyond mere descriptions of data to
inferences about specific populations. The book is divided into two
parts. Part I introduces readers to fundamental definitions,
theorems, and methods within the context of discrete sample spaces.
It addresses the origin of the mathematical study of probability,
main concepts in modern probability theory, univariate and
bivariate discrete probability models, and the multinomial
distribution. Part II builds upon the knowledge imparted in Part I
to present students with corresponding ideas in the context of
continuous sample spaces. It examines models for single and
multiple continuous random variables and the application of
probability theorems in statistics. Probability for Data Scientists
effectively introduces students to key concepts in probability and
demonstrates how a small set of methodologies can be applied to a
plethora of contextually unrelated problems. It is well suited for
courses in statistics, data science, machine learning theory, or
any course with an emphasis in probability. Numerous exercises,
some of which provide R software code to conduct experiments that
illustrate the laws of probability, are provided in each chapter.

Concept, and Application breaks down various data analysis
techniques to help students build their conceptual understanding of
key methods and processes. The information in the text encourages
discussion and consideration of how and why data analysis plays an
important role in the fields of criminal justice and criminology.
The book is divided into three units. Unit 1 discusses how data
analysis is used in criminal justice and criminology, various
methods of data collection, the importance of identifying the
purpose of analysis and key data elements prior to analyzing
information, and graphical representation of data. Unit 2
introduces students to samples, distributions, and the central
limit theorem as it relates to data analysis. This section provides
students with the essential knowledge and skills needed to
understand statistical concepts and calculations. The final unit
explains how to move beyond statistical description to statistical
inference and how sample statistics can be used to estimate
population parameters. Highly accessible in nature, Data Analysis
in Criminal Justice and Criminology is ideal for undergraduate and
graduate courses in criminal justice, criminology, and sociology
especially those with emphasis on data analysis.

Classification and regression trees (CART) is one of the several
contemporary statistical techniques with good promise for research
in many academic fields. There are very few books on CART,
especially on applied CART. This book, as a good practical primer
with a focus on applications, introduces the relatively new
statistical technique of CART as a powerful analytical tool. The
easy-to-understand (non-technical) language and illustrative graphs
(tables) as well as the use of the popular statistical software
program (SPSS) appeal to readers without strong statistical
background. This book helps readers understand the foundation, the
operation, and the interpretation of CART analysis, thus becoming
knowledgeable consumers and skillful users of CART. The chapter on
advanced CART procedures not yet well-discussed in the literature
allows readers to effectively seek further empowerment of their
research designs by extending the analytical power of CART to a
whole new level. This highly practical book is specifically written
for academic researchers, data analysts, and graduate students in
many disciplines such as economics, social sciences, medical
sciences, and sport sciences who do not have strong statistical
background but still strive to take full advantage of CART as a
powerful analytical tool for research in their fields.
This book integrates philosophy of science, data acquisition
methods, and statistical modeling techniques to present readers
with a forward-thinking perspective on clinical science. It reviews
modern research practices in clinical psychology that support the
goals of psychological science, study designs that promote good
research, and quantitative methods that can test specific
scientific questions. It covers new themes in research including
intensive longitudinal designs, neurobiology, developmental
psychopathology, and advanced computational methods such as machine
learning. Core chapters examine significant statistical topics, for
example missing data, causality, meta-analysis, latent variable
analysis, and dyadic data analysis. A balanced overview of
observational and experimental designs is also supplied, including
preclinical research and intervention science. This is a
foundational resource that supports the methodological training of
the current and future generations of clinical psychological
scientists.
