Many sites publish fantasy football players’ average auction values (AAV) for use in auction drafts.  But these auction values often assume you play in a 10-team league.  If you have a different number[...] The post How Do Auction Values Differ by the Number of Teams in Your League? A Multilevel ... [Read more...]

Source: Wikimedia An all too common approach to modeling in data science is to throw all possible variables at a modeling procedure and "let the algorithm sort it out." This is tempting when you are not sure ... [Read more...]

The graph above recently appeared as part of Scott Walker’s Twitter feed. Presumably, the idea is to suggest that under Walker’s leadership, Wisconsin has done better than the country as a whole when it comes to unemployment, though an alternative version of the ad makes it somewhat more ...

Today, at JSM 2015, in Seattle, I attended several Bayesian sessions, having sadly missed the Dennis Lindley memorial session yesterday, as it clashed with my own session. In the morning sessions on Bayesian model choice, David Rossell (Warwick) defended non-local priors à la Johnson (& Rossell) as having better frequentist properties. Although I ... [Read more...]

Occasionally when I am jotting some code I find myself creating several temporary variables with the intention of later getting rid of them. These variables involve quick names that are defined in a local scope and get quite confusing out of their … Continue reading → [Read more...]

One of my papers that has attracted a lot of attention lately is "The Fallacy of Placing Confidence in Confidence Intervals," in which we describe some of the fallacies held by the proponents and users of confidence intervals. This paper has been discussed on twitter, reddit, on blogs (eg, here ... [Read more...]

For the past 6 months I’ve been working on an inverse modeling project as a ‘starter’ graduate project, and today I am announcing that I can see the light at the end of the tunnel. While there is certainly more work ahead, especially with regards to the manuscript,  the model ... [Read more...]

In case you missed them, here are some articles from July of particular interest to R users. An alternative to stacked bar charts with the streamgraphs package. Joseph Rickert shares his process for creating the monthly new and updated packages "spotlight" feature on MRAN. Using R to analyze data from ... [Read more...]

Some time ago i wrote on this blog about how to dockerize a Shiny App. If you don’t know what Docker is and what i mean by “dockerizing a Shiny App” i advise you to read this post before: Dockerizing a Shiny App I used this solution to create ... [Read more...]

This afternoon, at JSM 2015, in Seattle, we had the Bayesian Computation I and II sessions that Omiros Papaspiliopoulos and myself put together (sponsored by IMS and ISBA). Despite this being Sunday and hence having some of the participants still arriving, the sessions went on well in terms of audience. Thanks ... [Read more...]

More and more real-world systems are relying on data science and analytical models to deliver sophisticated functionality or improved user experiences. For example, Microsoft combined the power of advanced predictive models and web services to develop the real-time voice translation feature in Skype. Facebook and Google continuously improve their deep ... [Read more...]

The BASIC programming language was at one point the most widely spread programming language. Many home computers in the 80s came with BASIC (like the Commodore 64 and the Apple II), and in the 90s both DOS and Windows 95 included a copy of the QBasic IDE. QBasic was also the first ...

We just did a github release for an R package that provides an interface to the DomainTools API. It provides access to the core API functions that aren’t restricted (i.e. the ones we have access to): domaintools_api_key: Get or set DOMAINTOOLS_API_KEY value domaintools_username: ... [Read more...]

I like to turn coincidence into convergence whenever possible. This weekend, a user of cdcfluview had a question that caused me to notice a difference in behaviour between the package was interacting with CDC FluView API, so I updated the package to accommodate the change and the user.
