This post is by Phil Price A Washington Post article says “In the first study of its kind, researchers from Washington State University and elsewhere found a 14 percent greater risk of head injuries to cyclists associated with cities that have bike share programs.

## If you have a 45% chance of winning, is it “yours to lose”?

Nate Silver gives Brazil a 45% chance of winning the World Cup, with only Argentina and Germany having more than a 10% chance. My gut feeling is that that’s a bit high, but I’m no expert. What I find striking, though, is that the headline says it’s “Brazil’s to lose.” Huh? If we take Silver’s […]

## plus ça change, plus c’est la même chose

This post is by Phil, and I’m writing about the slow pace of change in 21st-century America. [Note added later: at the time that I wrote this, I was unaware that a year-and-a-half ago Andrew had written a similar post on the theme. I suspect I, and perhaps most of this blog's readers, missed it […]

## Everything I need to know about Bayesian statistics, I learned in eight schools.

This post is by Phil. I’m aware that there are some people who use a Bayesian approach largely because it allows them to provide a highly informative prior distribution based subjective judgment, but that is not the appeal of Bayesian methods for a lot of us practitioners.

## There are no fat sprinters

This post is by Phil. A little over three years ago I wrote a post about exercise and weight loss in which I described losing a fair amount of weight due to (I believe) an exercise regime, with no effort to change my diet; this contradicted the prediction of studies that had recently been released. […]

## The Great Race

This post is by Phil. Last summer my wife and I took a 3.5-month vacation that included a wide range of activities. When I got back, people would ask “what were the highlights or your trip?”, and I was somewhat at a loss: we had done so many things that were so different, many of […]

## Data problems, coding errors…what can be done?

This post is by Phil A recent post on this blog discusses a prominent case of an Excel error leading to substantially wrong results from a statistical analysis. Excel is notorious for this because it is easy to add a row or column of data (or intermediate results) but forget to update equations so that […]

## Subsidized driving

This post is by Phil. This DC Streets Blog post gives a concise summary of a report by “The Tax Foundation”. The money shot is here, a table that shows what fraction spending on roads in each state in the U.S. is covered by local, state, and federal gas taxes, tolls, registration fees, etc. (Click […]
