Statistical Graphics and more

Developing software in academia usually does not lead to commercial products, and if the intention is just this, the academic qualities often fail to reach common standards. Nonetheless, there is always the hope that commercial products might pick up the ideas generated in academic software projects. Being involved in many software projects on (interactive) statistical [...]

– That’s it for this year … After we all recovered from the “shock” that Spanish soccer is still hard to beat (no matter if you are Italian or German …) its time to look into this year’s Tour de France data. After the first 4 stages passed, I will start to log the results [...]

— that’s it for this year, see you in 2012 (the latest) - au revoir! — (With now 7 years of full Tour de France data, I might start to compare the different tours on a more “global” level.) Again, the Tour de France has to compete with the soccer world championship – ok, this time [...]

Sometimes the title may promise more than the post can hold … but I still try my best. As you might know, there is the usual visualization of the stage times, total times and ranks of all riders in the regular post to start with. As we have more data on the Tour and riders, [...]

July 3rd was probably the worst day to start the Tour de France, as many of us where captured by the quarter finals, which sent home nobody less than Diego Maradona’s dream team, which may dream for another four years now … Although the world cup yet has to see its best matches, I will [...]

It’s time again to trace the evolving Tour de France. This year is different as Lance Armstrong joined the field again and I am staying in France right now, attending the useR!2009 conference – this may probably limit my updates until Sunday … Stage Results cumulative Time Ranks (click on the images to enlarge) That’s [...]

Here we go in the fourth year after the years 2007, 2006 and 2005. Stage Results cumulative Time Ranks (click on the images to enlarge) “The trace of a winner” – (a spanish winner makes me suspicious though …) That’s it for this year!  (Thanks to Sergej for updating the scripts) 

It would be interesting to see, whether or not we could use graphics (or other statistical methods) to identify potential doping candidates … The only thing we would need is a list of drivers who either admitted doping are convicted  or are accused to be involved in doping.  At least we could use the list [...]

That’s it for the 2007 chaos tour. Looking at the time distributions makes everybody above the median quite suspicious … more doping cases to come – maybe including A.C. Although many people claim little interest in the tour after the many doping cases, this is all the more a reason to check whether we will [...]

That’s it for this year. Au revoir 2007!. Stage Results cumulative Time Ranks (click on the images to enlarge) Prolog: Did anyone have Thor HUSHOVD on his list? Stage 01: Except for 5, all arrived in the peleton Stage 02: MC EWEN already on 3. Stage 03: First drop outs Stage 04: BOONEN still keeps [...]

Well, the Tour de France 2006 is only a few weeks ahead, probably still time to give an update on the 2005 data. We now have the data recompiled with drop outs (thanks to Sergej). Interesting to see that almost half of the cyclists categorized as “sprinter” don’t make it to the Champs-Elysees. Looking at [...]
