Tammy Jackson, a senior research statistician developer in the economics technology group, says her job is like taking a math test all day—but she wouldn’t have it any other way. With a background in matrices, linear algebra and math education, Tammy is proud of her work and has a keen eye for
Fraud detection presents myriad analytical challenges: gathering sufficient known cases to make typical modeling techniques possible, gathering inputs from disparate data sources, and combining expert knowledge from investigators with findings to be gleaned from the data in an efficient way. Of course, analysts can fall into the trap of thinking
In evolutionary biology there is an interesting concept called “punctuated equilibria,” which is used primarily to explain why the fossil record seems to abruptly change after long periods of apparent calm, or ‘stasis’ as it is called. To understand this better, think of a stairway where the length between each
I recently gave a talk to a group of engineering students at Duke University, located just down the road from our headquarters in North Carolina. A couple of days later, one of the students sent me an email asking a very good question: which skills should I build up to
My name is Tonya, and I’m a Statistician. It’s true. I’ve been one for almost 20 years now. I was crunching numbers and analyzing data long before statistician landed on the sexiest profession list. And now, it seems like that claim to fame has faded in the face of an
I can’t believe all that has happened in the 7 months since I last blogged about high-performance analytics, so I’m back to give you some updates from SAS R&D. The energy around this area keeps growing as more of our developers adopt the new high-performance architecture and target their developments
At Predictive Analytics World San Francisco this week I attended back to back sessions on econometrics, a word that doesn’t surface as often as I think it should. Bestselling books like Freakonomics: A Rogue Economist Explores the Hidden Side of Everything or Predictably Irrational: The Hidden Forces That Shape Our
My colleague Geoffrey Taylor recently wrote about the education and training of analytic resources and the potential shortage of these resources in the job market. My other colleague Russ Cobb addressed building an analytical workforce in his recent entry. What’s on my mind is what happens when you finally find
Happy New Year! Wishing everyone a prosperous and joyful 2012! The joyful festive atmosphere continues to pervade most Chinese families in Asia in the coming week, as we will be celebrating Lunar New Year (Spring Festival) on Jan 23rd . This date is determined by the lunisolar Chinese calendar. Alongside
It's true. "Big data" can be a problem and an opportunity. Many organizations have struggled to manage, much less profit from, the deluge. In 2012, look for big data to spur demand for big data analytics. New developments in high-performance computing as well as increased demand for visualization and text
Big data has been a hot topic recently, but more often than not the topic is covered from an IT perspective. What do the analysts, data miners and statisticians think? I recall the old days discussing with statisticians what data mining is and how it fundamentally differs from statistics. In
As the Basel Accords continue to drum up attention in the global financial markets, many institutions are looking at how they can strike a balance between capital requirements and competitive advantage. One area of focus is consumer credit risk modelling and scoring, as the more accurate and robust the models
“Wise Enterprise: Best Practices for Managing Predictive Analytics” was the title, and the assignment to the panel at the recent Predictive Analytics World conference in New York was to share “poignant moments of failure.” Wayne Thompson from SAS began, going back ten years to describe a network intrusion project. He
Reflecting on my 25 years as a data analyst, I’ve always felt that there is something more to being a good applied statistician than just applying what I had learned from school. What are those key skills that make a good field statistician? Before analytics came into play, when presented with
Last week, a new film featuring Brad Pitt came to theaters, and for a change, I’ll be dragging my wife to see it instead of the other way around. Moneyball is based on the best-selling book by Michael Lewis (2003) which chronicles the new-age, statistically driven philosophy successfully adopted by
Emails – it’s hard to imagine that there used to be a time people worked without them – at least in our industry. When I started at SAS in 1996 the amount of business email I received on a particular day was almost less than the amount of spam mails
The promise of high-performance analytics, as I understand it, is this: Regardless of how you store your data or how much of it there is, complex analytical procedures can still access that data, conduct a series of calculations on that data and provide answers quickly, accurately and using the full
There are many things that I enjoy in life, but cooking and analytics are two of the things that excite me the most. In my free time, one of my favorite things to do is experiment in the kitchen to try to come up with something new and different to
Rome was not built in a day. Similarly, high-performance analytics is a product of many cumulative architectural, computational and analytical advances. The ability to solve complex business problems by applying algorithms from multiple disciplines to increasingly large volumes of data of all types - both structured and unstructured - is
This year, SAS joined the Coalition Against Insurance Fraud (CAIF). Not long ago I had a chance to attend my first CAIF meeting and I was very impressed with what I saw and heard. Fraud continues to be a thorn in the side of the insurance industry. The most recent
Recently, I had the privilege of visiting one of our small to midsize business (SMB) customers, Oberweis Dairy, a family owned, 90-year-old business located in the Chicago area. Essentially, Oberweis has morphed from a family dairy farm to a significant, regional food manufacturer and retailer. With 39 retail stores, 40,000
