Data Intelligence, Business Analytics
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.

First of all, our team is absolutely delighted that Judea Pearl won the ACM Turing Award, widely considered the "Nobel Prize in Computing". For well over a decade we've been exclusively committed to developing software based on Bayesian networks, a paradigm established…Continue

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

Three metrics can be used to segment the population of data scientists. Each metric has three levels: high, medium, low. Hence the 27 (= 3 * 3 * 3) types of scientists.
Here are the metrics in question:

The financial crisis – risk transfer, insurance layers and (no?) reinsurance culture
Michael Fackler freelance actuary Munich, Germany
The financial crisis of 2007 has triggered various debates, ranging from the stability of the banking system to subtle technical issues regarding the Gaussian and other copulas. All these debates are important, and it might be good to start even a further one: Credit derivatives have much in common with…

“Exploratory” and “conﬁrmatory” data analysis can both be viewed as methods for comparing observed data to what would be obtained under an implicit or explicit statistical model. For example, many of Tukey’s methods can be interpreted as checks against hypothetical linear models and Poisson distributions. In more complex situations, Bayesian methods can be useful for constructing reference distributions for various plots that are useful in exploratory…Continue

In the last months we discussed a lot about text mining algorithms, I would like for a while focus on data mining aspects.
Today I would talk about one of the most intriguing topics related to data mining tasks: the regression analysis.

Ever since the ﬁnancial crisis of the banking system of 2008 - 2010 the paradigm that deposits or other exposures towards major banks are safe has been fundamentally questioned. This put industrial corporates, who to support their business usually need to manage signiﬁcant cash holdings or incur counterparty credit risk via derivatives, in the situation to develop or extend their resources for counterparty credit risk management. This paper provides a…
