The FocuStat Blog!

FocuStat is a five-year project funded by the Research Council of Norway. The project group consists of five core members, along with further PhD and Master's level students and a few associated colleagues.

On this blog the members (and associated members) of the FocuStat group publish small statistical stories about interesting datasets or methods.

Some articles are in Norwegian (with an English summary), but most are in English.

Jeg ser at du smiler og jeg tenker at du er glad. På bakgrunn av en observasjon (et smil) gjør jeg en slutning om hvordan jeg tror verden er (du er glad). Få ting er så grunnleggende for oss mennesker som denne typen induktive slutninger. Vi gjør slike slutninger nesten hele tiden, hver dag, og all empirisk vitenskap innebærer å slutte fra observasjoner til hvordan man tror verden er. Faget statistikk består av matematiske formaliseringer av slike slutningsprosesser.

FocuStat-gruppen har den intensjon og tradisjon, at vi hvert år skal finne én anledning, på det store konferansekartet, der vi alle reiser (og deltar aktivt). I 2015 dro vi til ISI World Statistics Congress i Rio, komplett med sambaoid eksponering. I 2016 toppet vi dette, ved å dra til København!, til NordStat, den nordiske konferansen i matematisk statistikk, 27.-30. juni.

The Formula One event for cross-country skiers is the sprint, where the very best athletes need to go through four strenuous three-minute Olympic-intensity competitions in a row: prologue, quarterfinals, semifinals, finals. The winners, at the end of the process, seemingly have a tendency to come from the first of the two semifinals.

All men are created equal, proclaimed Jefferson in 1776 -- but some are more equal than others, added Orwell in Animal Farm. So what's the probability that two skaters are exactly equal, to the third decimal places, after four distances?

Full of adventures, battles and love stories, the chivalry romance Tirant lo Blanch is a masterpiece of medieval literature. The novel, sometimes claimed to be the world's first, is made even more fascinating by the fact that its original author died before its completion and another author had to take over. The mystery concerning where the change-of-author takes place constitutes a statistical change-point challenge.

I took part in the Johan Hjort Symposium (and even gave a dinner speech and wrote a paper later on, with Gudmund Hermansen and Olav Kjesbu). Kjesbu at the Hjort Centre for Marine Ecosystem Dynamics asked me to write up some personal reflections on this. This blog post is a mildly extended version of that note.

To begin the Christmas season, we ask an in itself unchristmassy question: what are the implications of getting a bonus roll when rolling a six on the dice in a simple dice game? Such a small tweak of the rules can be surprisingly important in determining the success of the Christmas celebrations.

14. desember 1912 fødes to jentebarn på hver sin side av jordkloden. 101 år og 11 måneder senere slutter hjertene deres å slå – med to timers mellomrom, på Lillestrøm. Hvor urimelig usannsynlig er en slik hendelse (og hva slags dramatiske, lange liv har de to levet)? På oppfordring fra journalister i A-magasinet har vi regnet på sannsynligheter relatert til denne hendelsen.

With a random selection setup, how come each of 8 games is a match between a top-league-team and a non-top-league-team?

The Game of Thrones universe is famous for its high mortality rates, but for persons belonging to the nobility the death tolls are quite similar to those of nobles living in England during the Wars of the Roses.

Det har nettopp vært kommunestyrevalg i Norge og valget i Oslo var et av de mest spennende på mange år. Slaget stod om høyresiden fikk beholde makten i hovedstaden eller om venstresiden skal ta over etter 18 år på innbytterbenken.

Men hvis man tar en titt på hva de ulike bydelene stemmer, ser vi raskt at det er store lokale forskjeller. Med åtte store partier (Ap, Høyre, Frp, SV, Krf, Venstre, MDG og Rødt) kan det virke vanskelig å få det fullstendige bildet av hvordan stemmene fordeler seg i sentrum, øst, vest, sør og nord. Det viser seg likevel at partimøstrene kun varierer langs noen helt få, men forståelig, dimensjoner.

We all watched Norway-Spain 28-25 today (21-Dec-2014), with Norway winning the European Championship 2014. But how exciting was it? In precisely how dire straits did Norway find herself when Spain was leading 10-5 after 18 minutes, and could we really start relaxing when Norway led 26-22 after 52 minutes?
