Correspondence Analysis in Practice - 3rd Edition


The third edition of my book Correspondence Analysis in Practice was published in December 2016.  This is a totally revised and extended version compared to the second edition. Trevor Hastie gave it a nice endorsement, which appears on the back cover:
"This great book has become greater, and not just by the extra five chapters. Michael Greenacre has extended the scope of correspondence analysis in this third edition into new and interesting areas, such as network analysis and compositional data. Like the previous edition, this one sticks to the module format, making it ideal as a teaching text. This is an authoritative book by one of the world experts, written in an accessible style."
Some more reviews can be seen here.

below the surface

Two years in the making, first recordings of voice and guitar at One Ton Studios,Victoria, Canada, in July 2012, additional music added by the best musicians I know during 2012 and 2013 in the Emergency Room Studios, Barcelona   Mixed at the same studios in Barcelona and  mastered in the USA in 2014, finally "below the surface" was born, the new album of Gurdeep Stephens, Santi Careta and myself, with a lot of invited guests.

(click on CD cover to enlarge it and see the song selection)

Because our first album was called "you, woman" - see the other blog post below - we three now call ourselves the youwomangroup, with YouTube channel www.youtube.com/youwomangroup.

Like the first album, all the music is my own, composed many years (decades?) ago, and finally laid down permanently.  There are poems in five languages: English, French, Italian, Afrikaans and Greek.  Take a listen to the title track, featuring the three of us, Gurdeep singing, Santi on electric guitar and banjo and myself on classical guitar:

Analysing data in ecology

My latest book is on analysing multivariate data in ecological research. "Multivariate" means consisting of many variables, which is important since biological diversity is the product of the interaction between many living species, as well as the many factors that characterize the environment in which the species live.   Multivariate Analysis of Ecological Data is a comprehensive and structured explanation of how to analyse and interpret ecological data observed on many variables, both biological and environmental. Written with Raul Primicerio, from the Unıversity of Tromsø, the book is available for free download at the website www.multivariatestatistics.org, thanks to the publisher, the BBVA Foundation in Spain.

Water Wind Sun & Sea

Coinciding with the climate conference in New York, we have published the video clip of this Renewable Energy Song, with the chorus
"Why are we still burning coal when there's Water, Wind, Sun & Sea!"
 This was a 20-month long project, from the original idea to the video posted on youtube:



As many as 30 people contributed internationally to the video, including 13 young kids in Victoria, Canada, who do the acting and singing, seven musicians from Barcelona, Spain, and an art student in Eskişehir, Turkey, who did most of the animation.  Lyrics can be found here.

Will.i.am: from Black Eyed Peas to science & tecnology promotor

Inspiring interview with Will.i.am on the BBC. One of his songs was played back to earth from the Mars explorer.

Non-linear forecasting banned!


Hey, here's a good one for the statisticians
and climate scientists.
The government of North Carolina has forbidden the use of non-linear forecasts for the effects of climate change on their sea-level! Only linear forecasts allowed... See a news report in USnews or listen to the short BBC news report on the subject on 1 June 2012 (player below) .



The One-Minute Correspondence Analysis Course

After a brief introduction to the "famous" smoking data (which is longer than the course!) I give my 1-minute CA course, first presented at the Australian Market and Social Research Society conference in Sydney in 2009.

Advice for life: "Do what you like doing!"

Xavier Sala-i-Martin of Columbia University in New York and the Universitat Pompeu Fabra in Barcelona, talks to Manel Fuentes on Catalunya Radio about Pep Guardiola's passion for his work and goes on to encourage young people to choose in life what they like doing, not what might gain them the most money.  This fantastic piece of advice, so well put by Xavier, is in Catalan, but worth transcribing into English, which I'll try to do soon!

The Singular Value Decomposition Song

For my invited talk, Biplot Videos, at the 9th Tartu Conference on Multivariate Statistics (organized jointly with 20th International Workshop on Matrices and Statistics) at the end of June 2011, I included a video of a song that I wrote. This song, called "It had to be U", is about the result in matrix algebra that is the most useful in my research: the singular value decomposition, or SVD. The song was recorded the week before by the inimitable Gurdeep Stephens, accompanied by Lisa Olive, in Victoria, British Columbia, Canada. The recording studio in Canada sent me the mp3 file, I added the visuals and some narration, and the result is a compact explanation of this mathematical result -- in song!



You will find other songs by Gurdeep further down in my blog, especially The Millennium Song, which she sings in various languages.

Cas Troskie

Cas Troskie
My book Biplots in Practice (see later below) is dedicated to Cas Troskie, who passed away earlier this year.  In the preface of my book I wrote the following: 


"This book is appropriately dedicated to Prof. Cas Troskie, former head of the Department of Statistical Sciences at the University of Cape Town (UCT), South Africa, and a maestro of theoretical and applied multivariate analysis.  Cas was one of the most influential people in my statistical career, in fact when he visited me on Barcelona on several occasions I always introduced him as the reason behind my decision to do Statistics as a major in my initial Bachelor of Science studies at UCT.  As early as 1969, aged 33 and the youngest department head on the UCT campus, he was encouraging students like myself to write computer programs and put decks of punched cards into card readers linked to the university computer and wait expectantly for printouts to emerge with the results.  He had a singular faith in principal components of a data set, which prepared me for my subsequent studies in France on correspondence analysis.  I am not alone in being affected by his dynamic personality and sharp intelligence, since he inspired dozens of Masters and PhD theses, leaving a huge legacy to the statistical community, not only in South Africa but worldwide."
