Living abroad brings a lot of experience and surprises. One of them is to enjoy countries’ diversity and customs for particular holidays that are not celebrated in the homeland. The other thing is when you discover on your calendar a vacation day due to some national event about which you had no idea. Another time, national vacations could bring troubles when it comes to cooperation between nodes in different countries. Continue reading “Multidimensional Scaling of National Holidays”
I am happy to report that an important new product of the AMVA4NewPhysics ITN is now public. This is generically titled “Report on a Statistical Learning Method for Model-Independent Searches for New Physics“, and labeled D4.2 as per the grant agreement we signed with the European Union. The document is available at the following link:
What is this document about ? It is a description of the studies for the development of a software package aiming at automating the searches for new physics in LHC data, by evidencing anomalous clusterings of events that are hard to explain with known physics processes. I am sure that Fabricio and Grzegorz, the two main developers of the software (Deliverable 4.3, available on github at https://github.com/Grzes91/PenalizedAD) and its documentation (D4.2) will be happy to post in this blog a more complete description of the new package and its possible uses in particle physics research.
Yesterday, October 20, was the international day of Statistics. I took inspiration from it to select a clip from chapter 7 of my book “Anomaly! Collider physics and the quest for new phenomena at Fermilab“ which attempts to explain how physicists use the concept of statistical significance to give a quantitative meaning to their measurements of new effects. I hope you will enjoy it….
As we near the discussion of the discovery of the top quark, we need to make a digression to explain an important concept used by particle physicists to measure the level of surprise of an observation, i.e., how much are data at odds with a hypothesis. In a nutshell, the statistical significance of an observed Continue reading “What is Statistical Significance?”
So, it’s been a while since my last post, apologies for that, but the summer has been both busy and eventful, so let me summarise what’s been happening. Continue reading “Summer activities at LIP-Lisbon”
On Friday, September 8 th I attended a Sino-Italian workshop on astrostatistics organized at the Department of Statistical Sciences in Padova. It touched current topics at the interface between Astronomy, Physics and Statistics. At a first glance, I was surprised by the similarity of the research topics that are faced across different fields of science. Often the main difference lays only in the data and the assumptions of the underlying data generating process. Continue reading “Astro@stats Workshop”
On September 8, 2017 the Department of Statistical Sciences of the University of Padova will host Astro@Stats 2017, a Sino-Italian Workshop on Astrostatistics. Continue reading “Invitation to Astro@Stats 2017”
On the 19th of May I was very glad to take part in the RooStats tutorial organised by the AMVA4NewPhysics Network as a part of a workshop in Oviedo. RooStats is a ROOT library that uses the “RooFit” package, and provides classes to perform statistical analysis. The tutorial was attended by all the ESR from our Network, among which I was the only non-physicist. I am a statistician who does not use ROOT at all. For this reason, my attendance at the tutorial could seem Continue reading “My impressions on the RooStats Tutorial”
Just in time for our 4th all-network workshop, the AMVA4NewPhysics ITN reached full capacity with the addition of the two final ESRs, Seng (Munich) and Ioanna (Athens). The aforementioned workshop was hosted by the University of Oviedo, itself a recent addition to network, and organised by our outreach officer, Pietro, who did Continue reading “AMVA4NewPhysics: Fully-Armed and Operational!”
