Statistical Songs Roundup

by

Today is clearly a day for statistical songs (are there any other days?), so here are some links to get you started. To kick of the stat song roundup, here are some … interesting insights into the culture that is biostatics, complete with some remarkably dreadful audio material. Obviously, youtube has a whole channel devoted…

My Exodus from Google Reader

by

Like many fellow information junkies, I was shocked that Google is killing Reader, then realised that I had not used it very regularly  lately. This is partly because I rely a bit more on twitter these days, partly because last year I began using feedly, a Reader frontend that looks good on my various devices…

What Kind of Detective are you, method-wise?

by

Pat Thomson – drawing on work by Noel Gough – likens epistemological positions to crime-novel heroes. Turns out I’m a positivist (or post-positivist? why post-?) Sherlock, though I would rather be a Sam Spade or Philip Marlowe  (guess their epistemological vantage point). They are way cooler, and I’d prefer the Bourbon over the morphine. What kind of detective are you?

Random Fun Fact of the Day: Machine Learning and Statistics

by

Every sentient and internet enabled being in the Western world has by now noticed that Amazon’s “customers who bought this item” algorithm is one of the most successful exercises in machine learning. Like various algorithms used by Google, it is oftentimes accurate as well as slightly frightening.

A friend of mine (who is an engineer) told me that he bought an administrator’s guide to Cisco routers. Amazon concluded that he might also be interested in “Cooking for one”. I, on the other hand, recently browsed the excellent Cambridge “Dictionary of Statistics” and also had a look at “All of Statistics” (preposterous title, but an interesting book – incidentally, it tries to convey statistical basics to engineers interested in machine learning). Amazon suggested to round off my order with – drum roll – “Fifty Shades of Grey”. I’m sure my students would agree that there is an intimate link between these three titles.

Data: How many people are shot dead or otherwise killed in OECD countries?

by

As a follow-up to my recent post on the relationship between gun ownership and gun homicide in OECD countries, I have rolled my dataset (compiled from information published by gunpolicy.org) and my analysis script into a neat Stata package. If you want to recreate the tables and graphs, or otherwise want to play with the…

How many people die each year because of the “Second Amendment”? My estimate is 8000+

by

Following Friday’s events, the attached image went viral. The figures (if correct) are certainly suggestive, but obviously, the population at risk varies widely between countries. What we need is the gun-related homicide rate for a sample of comparable countries. I headed over to the Brady Campaign, which had created the image, but could not easily…
