Biography
Lukas Meier is a senior scientist at the Seminar für Statistik at ETH Zürich. His main interests are teaching statistics at various levels, the application of statistics in many fields of applications using advanced ANOVA or regression models, and high-dimensional statistics. He co-leads the statistical consulting service at ETH Zürich and is the director of a continuing education program in applied statistics.
"I found this to be a well-written, practical, concise, and very clear handbook on the appropriate analysis of data from randomized experiments using the freely available R software. The book comes in at 187 pages including the references and the index, so it gets right to the point without a lot of extra words. This book will be easy to understand for practitioners from many different fields who are collecting and analyzing data from randomized experiments, and the consistent focus on data management and data analysis using R is excellent. This is a wonderful little handbook that should be on a lot of desks. Who is it best for? First, I see this as a supplemental textbook/handbook for an undergraduate or graduate course on the design and analysis of randomized experiments. Some background in probability and statistics is needed, so this could be used for a year-3 or year-4 class in an undergraduate sequence in statistics or a graduate course on experimental design taught in a non-statistics department to students with some prior coursework in statistics. Second, professional researchers and data analysts who are comfortable with R and frequently find themselves analyzing the results of randomized experiments will also find this book very useful. I enjoyed reading it and will definitely make use of it in my work as an applied statistician and survey methodologist."
~Brady T. West, The American Statistician"The material is presented in an easy-to-read format targeting readers who seeks to understand the general principles of popular experimental designs with examples showcasing how to analyze corresponding data and interpret the outputs in RI feel this book succeeds in giving a good introduction to ANOVA and mixed effects models using R. It shows the importance of understanding the scientific question at hand when planning an experiment to enable meaningful analyses. For those who teach courses where analyzing data with ANOVA and mixed effects models are needed with a reduced theoretical overhead and an increased emphasis on interpretation and application of the methods in R, this book merits consideration."
~Oluwagbenga David Agboola, Journal of Quality Technology"To conclude, this book is a companion book to introduce the analysis of data fromexperimental designs. It provides an excellent basis to the comprehension of the theoreticalconcepts of ANOVA and mixed models with developedexamples. This book is accessible toall readers with a background in statistics and probability."
~Sébastien Bailly, Grenoble Alpes University, France, ISCB News, May 2024"The book presents a clear and easy introduction to the use of analysis of variance (ANOVA) and
mixed models, with examples of the use of experimental design in agricultural field trials.
Concepts presented in the book have a well-thought-out narrative from basic principles of experimental
design to implementing and understanding random effects. . . Throughout the book, R examples showing how to fit ANOVA or mixed effects models use either the aov or lmer function. Analysis examples are well contained to each chapter with datasets available from the author’s website. Example datasets used include those from agricultural field experiments and also a bike tyre dataset."
