| 2009/12/08 Leverage Statistical Control Limits
One factor that is not appreciated enough is that every metric that you report tends to have a natural "biorhythm", i.e. those metrics will fluctuate up or down and change due to "natural occurrences" that just happen (I can see some of you cringe! :)). These biorhythms are hard to understand, harder still to predict and since many of us live in the Puzzle world rather than the Mystery world we spin our cycle like crazy to understand the numbers to "explain" them to the management so that they can take some action. Imagine getting a daily / weekly trend and it goes up and down and you have no idea what the heck is causing it, even after you have done your damdest to isolate all the variables. The result of these natural biorhythms is that it causes Analysts and Marketers to do analysis and deep dive where none is necessary, it causes some of us to look "bad" because we can't explain the data, and it causes a lack of faith the the ability of data to provides insights....

| 2009/07/23 Rise of the Data Scientist
As we've all read by now, Google's chief economist Hal Varian commented in January that the next sexy job in the next 10 years would be statisticians. Obviously, I whole-heartedly agree. Heck, I'd go a step further and say they're sexy now - mentally and physically. However, if you went on to read the rest of Varian's interview, you'd know that by statisticians, he actually meant it as a general title for someone who is able to extract information from large datasets and then present something of use to non-data experts....

A 20-minute talk by Jeff Veen from Small Batch, Inc., also known from WikiRank, which was originally given at the Web2.0 Expo in San Francisco a couple of weeks ago. During the talk, he focuses on some of the classic examples of information visualization (John Snow pump, Minard's map, the tube map, and so on), the issue of "decorating" data versus making it accessible, and the emerging challenge to empower lay people to participate in visualizing and analyzing their own data....

| 2009/04/30 BeyeNETWORK: Bayes and Business Intelligence, Part 1
From a business intelligence perspective, a major advantage to the Bayesian approach is the learning that accumulates over time. Indeed from a BI perspective, the Bayesian model is best viewed as a systematic learning approach for intelligence and decision-making for business. The posterior probabilities for analysis one become the prior probabilities for analysis two; the posteriors for analysis two become the priors for analysis three, etc. Thus the Bayesian orientation promotes learning and better decision-making, all the while refining priors to be more reliable and less “subjective” over time....
