50 unusual ways analytics are used to make our lives better

Many more to come soon. Let's start with 10 for today.
  1. Automated patient diagnostic and customized treatment. Instead of going to the doctor, you fill an online (decision tree type of) questionnaire. At the end of the online medical exam, customized drugs are prescribed, manufactured and delivered to you: for instance, male drug abusers receive a different mix than healthy females, for the same condition. In short,…

J.D. Opdyke, Author: A Powerful and Robust Nonparametric Statistic for Joint Mean-Variance Quality Control

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…

27 types of data scientists - where do you fit?

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:

  1. Soft skills: sales, business…

risk transfer, insurance layers

The financial crisis – risk transfer, insurance layers and (no?) reinsurance culture

Michael Fackler  freelance actuary Munich, Germany



Abstract



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 Data Analysis for Complex Models

Andrew GELMAN

“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…

Counterparty Credit Risk Management in Industrial Corporates

Abstract



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…

What is a Data Scientist?

Interesting article posted in The Guardian (see below). Here's my answer to this question:

A data scientist (I like the term data wizard better) is someone who can consistently derive money out of data, e.g. working as an employee, consultant or in an other capacity, by providing value to clients or extracting…

Visualization Databases for the Analysis of Large Complex Datasets

Saptarshi Guha / Paul Kidwell / Ryan P. Hafen / William S. Cleveland

Abstract



Comprehensive visualization that preserves the information in a large complex dataset requires a visualization database (VDB): many displays, some with many pages, and with one or more panels per page. A single display using a specific display method results from partitioning the data into subsets, sampling the subsets, and applying the method to each sample, typically one per panel.…

Features Extraction: Co-occurrences and Graph clustering

In the last two post we have discussed about co - occurrences analysis to extract features  in order to classify documents and extract "meta concepts" from the corpus.

We have also noticed that this approach doesn't return better than the traditional bag of words.

I would now explore some derivation of this approach, taking advantage of the graph theory.

the graph of the co occurrences is really huge and complex, how could we reduce its complexity without big information…

New Article on Data Mining: Classifiers & the ROC Curve

Many customer behaviors have the flavor of a choice between two alternatives:  Yes or no.  Buy or sell.  Renew or cancel.  Suppose software called a “classifier” is available to predict customer choices in advance.  Would you use it?  Perhaps you’d like to test it to see how well it performs before you commit.  In this installment of my series on the nuts and bolts of data mining, I discuss the use of classifiers and questions about their performance.  Regarding performance, we specifically…
