I had a great time at ICOTS9. Academic conferences are a bit of a lottery, but ICOTS is two for two for me. Both ICOTS8 and ICOTS9 were winners – enjoyable, interesting and inspiring. I’ve just returned from ICOTS9 in … Continue reading →

Il semble que l’ouvrage approches statistiques du risque, édité par Jean Jacques Droesbeke, Myriam Maumy-Bertrand, Gilbert Saporta et Christine Thomas-Agnan soit finalement paru, selon Gilbert Saporta. Ou devraient paraître – au pire &#...
This week I’ve been feeling tired of excessive fanaticism (or zealotry) of open source software (OSS) and R in general. I do use a fair amount of OSS and pushed for the adoption of R in our courses; in fact, I do think OSS is a Good ThingTM. I do not like, however, constant yabbering […]
« Dans ce contexte d’incertitude, il est particulièrement réconfortant de revenir aux sources, aux fondamentaux, c’est-à-dire aux mathématiques et de rappeler que le risque naît de l’aléa et s’appréhende grâce aux développements les plus avancés du calcul des probabilités. » (Claude Bébéar, dans la préface du tome 1) Après avoir été épuisé plusieurs semaines (voire plusieurs mois ?), une nouvelle impression du tome 2 de Mathématiques de l’Assurance Non-Vie, coécrit avec Michel…
Tomorrow, around noon, I will be giving a talk on predictive modeling for actuaries. In the introduction, I will get back shortly on the idea that a prediction is usually a best estimate, in the sense of getting an expected value. And because it is natural to use least square ideas. In order to illustrate all those concepts, we will use a simple dataset, with the sex, the height and…
I will give, with Qichun Xu, a joint webinar for the Reinsurance Council and the Futurism Council of the Society of Actuaries, on Perspectives of Predictive Modeling with Case Studies in a few days. The slides of my talk are now available (I do recommand to open the pdf version of the slides with Acrobat, since there are animated pictures in the slides that could not be visualized below for instance).…
For a good overview of what OCR is, check out this overview I found myself cutting the spines off books, again. This time it was because I couldn’t find an e-book copy of ‘Animal Liberation’ anywhere on the net, and I’ve amassed quite a few physical copies--mostly from garage sales--that I could afford to experiment »more
On va encore dire que je fais mon numéro d’anti-journaliste primaire, mais je voulais revenir sur une histoire, relayée par certains journaux (français) qui me laisse songeur sur les liens entre les journalistes et le milieu scientifique. Je ne reviendrais pas sur l’information que j’avais relayée alors (que @Tournyol a reprise sur Twitter ce week-end, et qui a beaucoup circulé ces dernières heures sur Twitter) où plusieurs journalistes traduisaient “augmenté de…
I took a session on ‘Useful software for research’ for the new batch of research scholars. I hope sharing the slides useful to other research students. The software suggestions were sorted based on my experience and colleagues’ experiences. The presentation … Continue reading → The post Useful Softwares for Research appeared first on Fiddling with data and code.
We recently uploaded on http://hal.archives-ouvertes.fr/hal-00725090 a revised version of our work, with Ewen Gallic (a.k.a. @3wen) on Visualizing spatial processes using Ripley’s correction: an application to bodily-injury car accident location In this paper, we investigate (and extend) Ripley’s circumference method to correct bias of density estimation of edges (or frontiers) of regions. The idea of the method was theoretical and di#cult to implement. We provide a simple technique – based…
