Quick: Name the Western U.S. city most vulnerable to a terrorist attack. Is it Los Angeles, with its crowded roads that make quick escape impossible? San Francisco and its iconic bridge? Or Seattle with its Space Needle and busy port?
Try Boise, Idaho, with its, um, potatoes.
A new study funded largely by the Department of Homeland Security ranked 132… Continue

While social networking is a red-hot topic at Revenue and around the online marketing space, eMarketer has revised its U.S. social network ad spend projections downward.

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

That's NED for short - our Strathclyde university improve-our-methodology self-help group.
I like to think it can help both qualitative and quantitatives, but I suspect I'm the only mixed method member!

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

Ive been consulting with a National Park on how to improve estimates of visitor usage. they have door mounted meters but these are not considered very accurate. Here is a summary of my sample design:
SUMMARY: National Park Administrators are required to file monthly reports of visitor totals at various park facilities such as visitor centers. Although door mounted meters can and are used to estimate these totals, there are issues with the quality of meter counts. Meters are… 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

I gave a short seminar at National Marine Fisheries Services NMFS in Honolulu, Hawaii, entitled "Bayesian Mark-Recapture for Small Sample Sizes"
Mark-recapture methods are often used to estimate the abundance of rare or elusive populations but produce highly uncertain results when sample sizes are small. We develop a new estimator for a single-release, single-recapture experiment based on Bayesian methodology to handle this situation. The number of marked… Continue
