Those who attended my dataviz talks have seen a version of the following chart that showed up yesterday on New York Times (link): This chart shows the fluctuation in Arctic sea ice volume over time. The dataset is a simple...

This question comes from a comment on another post: I’ve seen authors citing as many references as possible to try to please potential referees. Many of those references are low quality papers though. Any general guidance about a typical length for the reference section? It depends on the subject and style of the paper. I’ve […]

Yesterday‘s winner is Mark Twain because, as Anonymous demonstrated in the comments, Twain on Eddy is more interesting than Eddy on Eddy. Today’s third-round match pits an eternal classic vs. the coolest of the cool. P.S. As always, here&#...

Bioconductor is one of the most widely used open source toolkits for biological high-throughput data. In this four week course, co-taught with Vince Carey and Mike Love, we will introduce you to Bioconductor's general infrastructure and then focus on two specific technologies: next generation sequencing and microarrays. The lectures and assessments will be annotated in

Sometimes you only need a rough fit to some data and a triangular distribution will do. As the name implies, this is a distribution whose density function graph is a triangle. The triangle is determined by its base, running between points a and b, and a point c somewhere in between where the altitude intersects the base. […]

Chess ratings are all about change. Did your rating go up, did it go down, have you reached 2000, who’s hot, who’s not, and so on. If nobody’s abilities were changing, chess ratings would be boring, they’d be nothing but a noisy measure, and watching your rating change would be as exciting as watching a […] The post Adiabatic as I wanna be: Or, how is a chess rating like…

When it comes to managing a portfolio of stocks versus a benchmark the problem is very different from defining an absolute return strategy. In the former one has to hold more stocks than in the later where no stocks at all can be held if there is not good enough opportunity. The reason for that is the tracking error. This […]

Having worked in finance I am a public fan of the Sharpe ratio. I have written about this here and here. One thing I have often forgotten (driving some bad analyses) is: the Sharpe ratio isn’t appropriate for models of repeated events that already have linked mean and variance (such as Poisson or Binomial models) … Continue reading One place not to use the Sharpe ratio → Related posts: A…

The American Association for Public Opinion Research (AAPOR) has put out its Big Data report last month (link). This one is worth reading. It has some of the most current citations, and readers of this blog will be very receptive to its core messages. The team who wrote the report is a mix of academics and practitioners. *** In Big Data, there are many self-evident truths, according to the people…

[This post is based largely on my 2013 article for Journal of Mathematical Psychology; see the other articles in that special issue as well for more critiques.]When I tell people that my primary area of research is statistical methods, one of the reactions I often encounter from people untrained in statistics is that “you can prove anything with statistics.” Of course, this rankles, first because it isn't true (unless you…

In watches, a complication is anything that goes beyond the basic function of showing the current time: alarm time, moon phase, etc. I think the term should be adopted in user interface design and visualization. With their upcoming Watch, Apple is clearly playing to horology and the long history behind the design of classic watches. They … Continue reading Complications

Not a lot of action on yesterday‘s post, so I don’t think the winner will advance any farther . . . But, in any case, I’ll call it for Carlin based on Jonathan’s amusing babble of postmodernist commentary. As for today: What can you say? A great pairing to close out the second round of […] The post Judy Garland (4) vs. John Waters (1); Carlin advances appeared first on…
