I was born in Michigan in 1961, went to the University of Michigan for my bachelors, and then post-graduate studies in pure mathematics at Wisconsin and Illinois. I finally got tired of working on topics that I couldn't talk to even my office mates about, so I got out with a MS in statistics. My first real job was fraud analysis for Medicare. I spent most of the 90's working for a bleeding-edge data mining firm called NeoVista and later Accrue. This century I've worked in health… Continue

In the latest issue of the Journal of Credit Risk, Bielecki et al. propose a dynamic bottom-up approach by using Markov copula for pricing and hedging credit index derivatives and ratings-triggered corporate step-up bonds.
The Markov copula procedure works efficiently and is a useful step towards developing a copula-like formalism for multivariate processes, which can be applied to the modeling of credit derivatives. Read the full article and receive the current edition of the… Continue

Loyalty Marketing has become a key strategy for most companies in today's competitive marketplace. The practice is based on a very simple premise - as you develop stronger relationships with your best customers, they will stay with you longer; the longer they stay, the more profitable they become.
It costs less to retain a customer than to acquire a new one. To retain a customer involves many factors - personal relationships, product quality, customer service, price, and other brand… Continue

The Predictive Model Markup Language (PMML) is a mark up language for statistical and data mining models. Some sort of HTML language to handle statisical tasks such as regression, decision trees etc.
PMML is an XML-based language which provides a way for applications to define statistical and data mining models and to share models between PMML compliant applications.
PMML provides applications a vendor-independent method of defining models so that proprietary issues and… Continue

PROC LOESS implements a nonparametric method for estimating local regression surfaces pioneered by Cleveland (1979); also refer to Cleveland et al. (1988) and Cleveland and Grosse (1991). This method is commonly referred to as loess, which is short for local regression.
PROC LOESS allows greater flexibility than traditional modeling tools because you can use it for situations in which you do not know a suitable parametric form of the regression surface. Furthermore, PROC LOESS is… Continue

My interest has mostly been in trading QQQQ and other major indexes, hoping to build a small portfolio of contrarian (negatively correlated) indexes. I am interested in two types of strategies:
1. A strategy where some cash is dormant on a trading account for most of the time, yielding a return of less than 4% a year when in "dormant mode". Once in a while (it could be every two or three years, sometimes every six months), when large movements occur on the stock market, I step in as… Continue

The purpose of this report is to gain a better sense of the people and teams who built and maintained business intelligence (BI) and data warehousing (DW) solutions during the 2007 calendar year. This report uses the term “BI” to refer to both business intelligence and data warehousing initiatives, and the term “BI professionals” to the individuals who deliver these initiatives. Specifically, the report looks at… Continue

The concepts surrounding the drive to Six Sigma quality are essentially those of statistics and probability. In simple language, these concepts boil down to, “How confident can I be that what I planned to happen actually will happen?” Basically, the concept of Six Sigma deals with measuring and improving how close we come to delivering on what we planned to do.
Anything we do varies, even if only slightly, from the plan. Since no result can exactly match our intention, we usually… Continue

Works well with non Gaussian data or outliers. Allows you to set up bounds on the regression parameters (similar to ridge regression). Does not use matrix inversion, thus numerically stable. Robust parameter estimation based on Monte-Carlo simulations and re-sampling. The source code can easily be modified to perform logistic regression. This package can be used by scientists, programmers, analysts or engineers with limited statistical knowledge. Works on Unix, Linux or Windows. We will help… Continue

What does Data Shaping mean?
The term was created in 1999 to fill a gap between data mining and statistics. Data shaping is about employing advanced statistical techniques to problems usually handled by computer scientists (machine learning, knowledge discovery, artificial intelligence, web mining). A data shaper is a true software engineer or computer scientist, and a true statistician at the same time, capable of extracting actionable information from large data sets, in… Continue
