Let's start the treasure hunt!
1. Don't always trust your data: often they are not homogeneous.
A good data miner must always check his dataset! you should always ask to yourself whether the data have been produced in a…Continue

In the data mining process, where do data scientists like you and me add the most value? Is it in exploring the data, uncovering anomalies and seeing relationships between elements? In selecting transformations for the elements to improve their representations for modeling…Continue

When Justin Bassett interviewed for a new job, he expected the usual questions about experience and references. So he was astonished when the interviewer asked for something else: his Facebook username and password.
Bassett, a New York City statistician, had just finished answering a few character questions when the…Continue
It’s been quite a while since business intelligence was the sole province of high-level strategic planners and C-level executives. Today, BI tools and analytics insights are being used by increasing numbers of people to answer immediate tactical questions and identify optimal courses of action. This trend has been enabled and accelerated by the consumerization of IT and the “democratization” of tech knowledge. As…Continue
Hospitals laying off workers, blaming in on fewer patients and lower revenue... No statistical model was able to predict it, although the explanation is obvious.

For statistical process control, a number of single charts that jointly monitor both process mean and variability recently have been developed. For quality control-related hypothesis testing, however, there has been little analogous development of joint mean-variance tests: only one two-sample statistic that is not computationally intensive has been designed specifically for the one-sided test of Ho: Mean2<=Mean1 and StDev2<=StDev1 vs. Ha: Mean2>Mean1 OR StDev2>StDev1 (see…Continue
