Book Information and Supplemental Files
1. The textbook
Foundations
of Statistics for Data Scientists, with R and Python , written
with Maria Kateri, has been published in November 2021 by
CRC
Press. Designed as a textbook for an introduction to
mathematical statistics for students training to become data
scientists, the book provides an indepth presentation of the topics
in statistical science with which any data scientist should be
familiar, including probability distributions, descriptive and
inferential statistical methods, and linear modelling. Compared to
traditional math stat textbooks, however, the book has less emphasis
on probability theory and more emphasis on using software to implement
statistical methods and to conduct simulations to illustrate key
concepts. All statistical analyses in the book use R software, with
an appendix showing the same analyses with Python. The book also
introduces modern topics that do not normally appear in mathematical
statistics texts but are highly relevant for data scientists, such as
Bayesian inference, generalized linear models for nonnormal responses
(e.g., logistic regression and Poisson loglinear models), and
regularized model fitting. It contains nearly 500 exercises. The
book's website has
expanded R, Python, and Matlab appendices and all data sets from the
examples and exercises.
2. The
book
An Introduction to Categorical Data Analysis, (Wiley, 2019)
was recently published in its 3rd edition. This new edition shows how
to do all analyses using R software and add some new material (e.g.,
Bayesian methods, classification and smoothing). This book, which
presents a nontechnical introduction to topics such as logistic
regression, is a lowertechnicallevel and shorter version of the
"Categorical Data Analysis" text mentioned above. I've constructed a
website for these texts that provides information about the use of
Software for
Categorical Data Analysis such as SAS, R and SPlus, SPSS,
Stata, and StatXact. Data files from the text are
at data files for Intro CDA. They
are also available at a
Github
site for CDA data files and at the
Wiley companion
website for Intro CDA. For some data files from the 2nd
edition, click on data files for Intro
CDA. For SAS files containing data sets from the 2nd
edition, click on SAS data sets
for Intro CDA. Here are
some corrections
for the 1st edition of this book, a pdf file
of corrections for the 2nd
edition, and a pdf file of
corrections for the 3rd edition. For those who use R, a
very useful and helpful R language compendium has been prepared by
Professor Raymond Balise. Containing code and formulas to accompany
this book, it can be found at
Balise
R compendium for Intro CDA. Its Github project
repository is public at Balise
Github R repository for Intro CDA.
3. The text
Foundations
of Linear and Generalized Linear Models, published by Wiley in
February 2015, presents an overview of the most commonly used
statistical models by discussing the theory underlying the models and
showing examples using R software. The book begins with the
fundamentals of linear models, such as showing how least squares
projects the data onto a model vector subspace and orthogonal
decompositions of the data yield comparisons of models. The book then
covers the theory of generalized linear models, with chapters on
binomial and multinomial logistic regression for categorical data and
Poisson and negative binomial loglinear models for count data. The
book also introduces quasilikelihood methods (such as generalized
estimating equations), linear mixed models and generalized linear
mixed models with random effects for clustered correlated data,
Bayesian linear and generalized linear modeling, and regularization
methods for highdimensional data. The book has more than 400
exercises. The book's
website
contains supplementary information, including data sets and
corrections. Here is
an interview
about the book in the Wiley publication "Statistics Views." Here is a
book review in the
journal Biometrics,a
book review
in Biometrical
Journal, and some reviews
at Amazon.
4. The
book
Strength in Numbers: The Rising of Academic Statistics Departments in
the U.S., coedited with XiaoLi Meng, has been published by
Springer (2012). This book has a chapter for each of about 40
Statistics and Biostatistics departments founded in the U.S. by the
mid1960s, describing the evolution of those departments and the
faculty and students who worked in them. Included are about 200
historical photos. See
the Springer site for other details.
5. The
text
Categorical Data Analysis, 3rd Edition
is in its third
edition (Wiley, 2013). I've constructed
a Website for
Categorical Data Analysis that provides datasets used for
examples, solutions to some exercises, information about using R, SAS,
Stata, and SPSS software for conducting the analyses in the text, a
list of some typos and errors, and powerpoint slides. For users of R,
Prof. Charles Geyer has prepared
a CatDataAnalysis
package for CDA at CRAN, with data files used in text
examples and exercises. He also has a website with
notes on
CDA for the course he has taught at the University of
Minnesota on categorical data analysis, with one section dealing with
infinite
ML estimates in canonical link models.
Here is
an interview
that the Wiley publication "Statistics Views" conducted with me to
mark the publication of the new
edition. A website
for second edition has some material for the 2nd edition.
Dr. Laura Thompson has prepared a detailed manual on the use of R or
SPlus to conduct all the analyses in the 2nd edition. Here is a
copy of this excellent resource:
Laura
Thompson R and S manual for CDA.
6. The
text
Analysis of Ordinal Categorical Data
(Wiley, 1984) has
been revised, and the second edition was published in 2010.
My ordinal categorical
website contains (1) data sets for some examples in the
form of SAS programs for conducting the analyses, (2) examples of the
use or R for fitting various ordinal models, (3) examples of the use
of Joe Lang's mph.fit R function for various analyses in the book that
are not easily conducted with SAS, Stata, SPSS, and standard functions
in R, and (4) corrections of errors in early printings of the book
(Please send me any that you notice). Here is the video for a
halfday course I taught in 2020 for the Harvard School of Public
Health on
Modeling
Ordinal Categorical Data.

The text >
Statistics: The Art and
Science of Learning from Data (5th edition, Pearson, 2021) was
written with Christine Franklin of the University of Georgia and
Bernhard Klingenberg of Williams College.
Professor Klingenberg has developed a wonderful set
of applets and other resources for teaching from the book
(see Art of
Stat ). This text is designed for a oneterm or twoterm
undergraduate course or a high school AP course on an introduction to
statistics, presented with a conceptual approach. The link
Table
of Contents has a Table of Contents and information about
the book. Many supplemental materials are available from Pearson,
including an annotated instructor's edition, a lab workbook,
videotaped lectures, and software supplements. Contact Ms. Suzanna
Bainbridge, the Acquisitions Editor for Statistics at Pearson
Education, for details (suzanna.bainbridge@Pearson.com). An Italian
translation of the 3rd edition is now available, thanks to Giuseppe
Espa, Rocco Micciolo, Diego Giuliani and Maria Michela Dickson at the
University of Trento.
8. The
book
Statistical Methods for the Social Sciences, (5th edition,
Pearson, 2018; 4th edition, by A. Agresti and
B. Finlay, published 2009) is designed for a twosemester sequence.
The book begins with the basics of statistical description and
inference, and the second half concentrates on regression methods,
including multiple regression, ANOVA and repeated measures ANOVA,
analysis of covariance, logistic regression, and generalized linear
models. The new edition adds R and Stata for software examples as
well as introductions to new methodology such as multiple imputation
for missing data, random effects modeling including multilevel models,
robust regression, and the Bayesian approach to statistical inference.
For applets used in some examples and exercises of the new edition, go
to applets.
These were designed by Bernhard Klingenberg for the text "Statistics:
The Art and Science of Learning from Data" (4th and 5th ed.) by Agresti,
Franklin, and Klingenberg. The book's
website
contains supplementary information, including data sets and
corrections. Special directories also have data files in
Stata format and in SPSS format. Some years ago, Jeffrey Arnold of
the U of Washington kindly set up a R package at CRAN for R users to
be able to access the datasets used in the 4th edition of this text.
See
R
data files. He has also put the data files at a GitHub
site,
data files at
GitHub. For examples of the use of the software Stata for
various analyses for examples in the 4th edition of this text, see the
useful site set up by
the UCLA
Statistical Computing Center. Thanks to Margaret Ross Tolbert for the
cover art for the 5th edition. Margaret is an incredibly talented
artist who has helped draw attention to the beauty but environmental
degradation of the springs in northcentral Florida (see
www.margaretrosstolbert.com). I am also pleased to report (due to my
partial Italian heritage) that there is also an Italian version of the
first ten chapters of the 4th edition of this book (Statistica per
le Scienze Sociali) and of the entire book (Metodi Statistici
di Base e Avanzati per le scienze sociali) published by Pearson,
and there is also a Portuguese version  see "Metodos Estatisticos
para as Ciencas Socias" at
Portuguese
SMSS  and a Chinese version, and it is being translated
into Spanish. I have developed Powerpoint files for lectures from
Chapters 112 of this text that are available to instructors using
this text. (Chapters 17 of these have also been translated into
Spanish by Norma Leyva of Universidad Iberoamericana in Mexico.)
Please contact me for details. Finally, here is a link to a workshop
held by the Department of Sociology, Oxford University, in 2012 that
discussed issues
in the teaching of quantitative methods to social science
students.
Short Courses
I have taught short courses on categorical data analysis topics for
many universities, professional organizations, conferences, and
companies, mainly in Europe and the U.S. These range in length from
halfday to a week, most commonly one or two days on topics such as
"Modeling Ordinal Categorical Responses," "Analyzing Clustered
Categorical Data," "Introduction to Categorical Data Analysis,"
"Discrete Data Analysis," and "Generalized Linear Modeling." Here is
the video for a halfday course I taught in 2020 for the Harvard
School of Public Health on
Modeling
Ordinal Categorical Data.

Participants at workhop in my honor,
"Categorical Data Analysis & Friends," Florence Italy, September 18,
2019.
"Grazie mille ad Anna Gottard per aver organizzato questo
meraviglioso evento." And thanks to my Italian friends who came from
Padova, Milano, Roma, Pavia, Firenze, Napoli, Venezia, Perugia, Parma,
Bologna, Bergamo, Cosenza, Trento, and Verona. Here is the program
about the
Florence workshop, and here is
the talk I gave with reminiscences of visits
to Italian universities.

under age 40; first award to Daniele Durante)
Here is a seminar (in mp4 format) on the
History of Categorical Data Analysis that I presented in
October 2015 at Istat (the Italian Census Bureau) in Rome, Italy
Here is a YouTube video of a seminar on
Simple Ways
to Interpret Effects in Modeling Binary and Ordinal Data
presented in 2021 for National University of Rosario, Argentina
(and also at La Sapienza University in Rome and Ca' Foscari in
Venice, Italy, and at Ohio State University)
Here are Power Point slides from a seminar on
Uncertainty (about Covid
and related things, in Italian), presented at Padova, Italy in
December 2020 by Antonietta Mira of the University of Insubria
(Italy) and University of Lugano (Svizzera Italiana), with my
help.

Poundwise guide to London from the DecemberJanuary 2007
issue of Gainesville magazine. (My wife Jacki Levine is founder and
was editor of this bimonthly magazine for 13 years.) More
uptodate, here is a useful site, courtesy of Rick Steves, about
experiencing untouristy London:
Untouristy
London. We would also suggest Borough Market, and the walk
along the south bank of the Thames from the South Bank arts complex to
the Tate and then Tower Bridge (that part is touristy), but then
further east to Rotherhithe, stopping at the Mayflower pub.
The picture at the top of my home page was taken by Jacki Levine in
the Forest of Dean, Gloucestershire, UK, among the May bluebells.
