The Visual Statistics book

bookWritten with Forrest W. Young and Michael Friendly, provides an intuitive approach to data analysis and statistics. You can download current version of ViSta here.


Dynamic-interactive graphics

This paper, with Ruben Ledesma, describes the history of dynamic-interactive graphics since the book Dynamic Graphics for Statistics was publised.

TV navigators

An interview in RTVE about the dangers of using navigators while driving.

Driving fitness and chronic illness

liverHepathic encefalopathy can produce cognitive impairment and limit fitness to driving as discussed in this paper


Instrumented cars

This paper in the journal of Accident Analysis and Prevention describes the experiences of three research groups (Spain, UK, and Greece) using highly instrumented cars for research. I am the first author of it.

The History of ViSta

ForrestA paper published in the journal Wiley Interdisciplinary Reviews explaining the history of ViSta, current situation, etc. A small tribute to Forrest W. Young that was the main developer of ViSta for so many years. Here is a link to the file.

Parallel analysis

This paper, with Rubén Ledesma as first author, presents a computer program for Parallel analysis and a review of methods for deciding the number of factors to retain in exploratory factor analysis.

Naturalistic driving

Naturalistic driving is an approach for research in traffic safety that involves collecting data from cars driven in real traffic. The project PROLOGUE funded by the EU was the opportunity for me to apply this methodology field trials.

Use of navigators

A paper published in journal iet intelligent transport systems on the use of navigators while driving.

Technical session DGT

The Dirección General de Tráfico (DGT) organizes technical sessions about research in traffic. The overheads for my presentation on naturalistic driving are here.

Loglinear analysis with ViSta

A paper in the JSS about a module of ViSta for performing loglinear analysis. I have improved it a lot since then and I still think its interface beats many other programs.

SPSS course

A course about multivariate analysis in SPSS. Here are the overheads for loglinear analysis. Ask me for the overheads for the other subjects if you are interested in them.

The first statistical plot

langrenMichael van Langren can be the first in drawing what can be regarded as an statistical plot. He was trying to sell a research project to the queen of Spain (sounds familiar?). Here is a link to the preprint of a paper coauthored with Michael Friendly and Joaquin Ibáñez-Udargui and published in the American Statistician.

JSS special issue on GUIs for R

RSpecial issue of the Journal of Statistical Software about GUIs for R. I was the Guest editor (with Rubén Ledesma).

Research group

The group SINTEC, which I am the director, is focused on new technologies and simulation studies in traffic and road safety.

JSS special issue on Lisp-Stat

xlispstatThis special issue of the Journal of Statistical Software evaluates the history of Lisp-Stat, a language for computational statistics popular in the 90s. I was the Guest editor for this special issue (with Frederic Udina).

Course on Visual Statistics

A course I lectured for the Eustat (the basque institute for Statistics) about interactive dynamic graphics. It is based on ViSta but I am working on an adaptation using commercial tools. The link has some written material. Click here for the lecture materials and here for other courses organized by Eustat (they are very interesting).

Teaching multivariate data

This paper was published in thequickcluster Journal of Statistics Education and describes three activities using dynamic graphics for teaching statistics. It includes videos (with me as narrator!)

Humanist conference

I was the president of the Humanist conference in Valencia in 2012. Humanist stands for Human centred design for Information Society Technologies and is a conference about human factors in in-vehicle driver information systems.

Groups of users

This paper describes methods for drawing the mental models of users (novice, experts, etc.) so big web sites can organized according to them. Good stuff that can be useful in applied settings. Ask me for a reprint if you want to get it all.


Chindogu is a japanese word that refers to things that look useful but are not. I did a presentation chindogubased on chindogus and HCI long time ago and I still think that this word should be part of the vocabulary of designers. There are so many examples!

Presentation on distraction

This presentation was for the I jornadas de movilidad urbana e interurbana in San Sebastion. The overheads are here if you are interested in them.

Bycicle helmets

I am member of a COST group on optimization of bycicle helmets.

Formal Methods in HCI

I wrote my thesis on formal methods in HCI. The document is here.

Gossip and Spreadplots

Spreadplots is an idea of Forrest Young that I contributed to develop by applying it to different statistical situations. I find many parallelisms between spreadplots and interactive dashboards for statistics but perhaps is only my opinion.
