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…

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.

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…
