International Prize in Statistics to Sir David Cox

Prominent British statistician Sir David Cox has been named the inaugural recipient of the International Prize in Statistics. Like the acclaimed Fields Medal, Abel Prize, Turing Award and Nobel Prize, the International Prize in Statistics is considered the highest honor in its field. It will be bestowed every other year to an individual or team for major achievements using statistics to advance science, technology and human welfare. 

This inaugural prize recognises Sir David’s seminal 1972 paper in which he developed the proportional hazards model that today bears his name. The Cox Model has been applied in many fields of science and engineering, from disease risk assessment and treatment evaluation to product liability, school dropout, re-incarceration and AIDS surveillance systems.

His mark on research is so great that his 1972 paper is one of the three most-cited papers in statistics and ranked 16th in Nature’s list of the top 100 most-cited papers of all time for all fields.

How Fast the Fastest Human Would Run 100m?

People have used extreme value theory to predict the records in various sports. Here is an articles which provides codes to visualize the same. One can update the dataset to take into account latest records. It's interesting to see how this updation affects the estimates:

The Median Isn't the Message

The Median Isn't the Message is the wisest, most humane thing ever written about cancer and statistics. It is the antidote both to those who say that, "the statistics don't matter," and to those who have the unfortunate habit of pronouncing death sentences on patients who face a difficult prognosis. Anyone who researches the medical literature will confront the statistics for their disease. Anyone who reads this will be armed with reason and with hope:

Some R Resources for GLMs

It is relatively easy to figure how to code a GLM in R. Even a total newcomer to R is likely to figure out that the glm() function is part of the core R language within a minute or so of searching. Thereafter though, it gets more difficult to find other GLM related stuff that R has to offer. Here is a far from complete, but hopefully helpful, list of resources.
