As a data scientist, I have the rare privilege of possessing the job title that Tom Davenport and others have dubbed the sexiest job in the 21st Century. As this popular job title catches on, I’ve even noticed a trend where customers make direct requests for help specifically from “the data
A deep-rooted belly laugh can do so much for your body, mind and spirit. Just the other night, my 15 year old daughter was shredding some items for me so she could earn a little spending money. The shredder indicated six pages maximum, but it really should have said one
This SAS tip is from Robert Virgile and his book “SAS Macro Language Magic: Discovering Advanced Techniques”. We hope you find this tip useful. You can also read an excerpt from Virgile’s book. In macro language, as in life, timing is everything. Macro language students need to learn the timing
The Monty Hall Problem is one of the most famous problems in elementary probability. It is famous because the correct solution is counter-intuitive and because it caused an uproar when it appeared in the "Ask Marilyn" column in Parade magazine in 1990. Discussing the problem has been known to create
Just this morning, the course leader at our newly created SAS Space & Astronomy School told me that they picked up a broadcast signal from outer space. By analysing all the data they have been collecting, they were able to quickly spot a spike in the trend pattern, which helped
It's a common problem: Your organization collects vast amounts and types of data – but it's spread across different departments and locations in various formats and systems. It’s a massive challenge to make all that data available, connected and usable to everyone who needs it. That was the scene at
This SAS tip comes from Clement A. Stone and Xiaowen Zhu, authors of Bayesian Analysis of Item Response Theory Models using SAS. Item response theory (IRT) models are the models of choice for analyzing item responses from assessments in the educational, psychological, health, social, and behavioral sciences. SAS PROC MCMC
Simplify scheint eines der Modewörter in der IT zu sein. Alles, was bisher komplex war, um enterprise-ready zu werden, wird nun in einfache Komponenten aufgesplittet, um in appetitlichen Häppchen serviert zu werden. Ob ERP, CRM, IOT oder eben Big Data - die neue Welt der IT soll so simpel sein,
The other day, I was looking at an enterprise architecture diagram, and it actually showed a connection between the marketing database, the Hadoop server and the data warehouse. My response can be summed up in two ways. First, I was amazed! Second, I was very interested on how this customer uses
Bookies have long turned a trade in predicting the fate of our politicians in the general election. According to Ladbrokes, gamblers are set to spend a staggering £100m betting on this year’s result. The outcome of the May 7 vote is anticipated to be the hardest election to predict in
This blog post discusses the use of a black background in a graph. But before we get started, I invite you to have a listen to one of my favorite songs - "Paint it Black" by the Rolling Stones. Perhaps this song subliminally persuaded people to use black backgrounds in
There has been a spate of recent high-profile airline crashes (Malaysia Airlines, TransAsia Airways, Germanwings,...) so I was surprised when I saw a time series plot of the number of airline crashes by year, which indicates that the annual number of airline crashes has been decreasing since 1993. The data
In today’s era of digital marketing, advertisers have access to innovative tools and platforms, which enable them to provide Internet users with more personalized ads.

In February of this year, the Washington Business Journal reported the US Government appointed its first Chief Data Scientist, DJ Patil. With this, I think it’s now safe to say that Data Science is officially sanctioned as new mode in organizations. Those that can apply the necessary finesse along with
In the Cold War techno-thriller WarGames, a marine monitoring a nuclear missile silo deep under the Nevada desert sees a red warning light blink on his console. “Just flick it with your finger,” his colleague tells him. He does, and the bulb goes out. Problem solved. But what will their
Am 24. März wurde Release 12 der statistischen Desktop Software von SAS Institute veröffentlicht. Neben erweiterten statistischen Analysemöglichkeiten und Datenaufbereitung, die man schließlich von solcher Software erwartet, haben die Entwickler um John Sall einige Hilfsfunktionen eingebaut, die wenig spektakulär daherkommen aber wesentlich zur Erleichterung der Arbeit mit Daten beitragen können.
Do you ever have stress dreams? You know, where you’re taking an exam for which you haven’t studied, or you’re forced to wait tables in a sea of angry restaurant customers? For many of us, the stress nightmare of the modern era involves trying to make sense of a never-ending
Having spent many years in graduate school, and living in the Research Triangle Park (RTP) in North Carolina, I have a lot of friends from other countries. Therefore when I recently saw some stories & graphs about EB-5 visas (where you invest a cool half-million US $ to bypass the

Bei der Herstellung von hochauflösenden Flüssigkristallanzeigen (engl. lyquid cristal display, LCD) werden chromophore Farbpigmente auf Nanometergröße gemahlen und dann weiterverarbeitet. Dieser Mahlprozess ist teuer. Ein Erkennen und Bestätigen der Hauptursachen für eine kürzere Mahlzeit sind somit zeit- und kostenkritisch. Doch wie geht man vor, wenn man aufgrund starker Wechselwirkungen (ein
Have you ever peered intently into an unfamiliar data delivery directory, realized what was in it, rolled over onto your side, stared blankly into the distance, and dejectedly uttered something akin to: "Spreadsheets! Why did it have to be spreadsheets?" If so, then we are definitely on the same page.
Jim Harris says the question of who owns big data is no longer an esoteric concept – it's a frequently debated topic.
In a noisy distribution environment, hotels are in significant danger of becoming commoditized. Differentiating themselves not only from the competition, but from the third party distributors, will be crucial to maintaining a competitive edge, or even just maintaining profitability. In an effort to connect better with guests, most hotel companies
Recently I have been out speaking with a number of organizations about the idea of the innovation lab concept , which I discussed in a previous blog post, as the way to unleash the power of big data and make even the largest of companies as agile as a startup. During my

Everyone loves a good conspiracy theory - hopefully you'll enjoy mine about the number of US E1 visas! I was perusing some of the US government charts, and found one on US immigration visas that caught my attention. It was a 3D bar chart, and since I always mistrust 3D
There's "big," and then there is "factorial big." If you have k items, the number of permutations is "k factorial," which is written as k!. The factorial function gets big fast. For example, the value of k! for several values of k is shown in the following table. You can
Increasingly, automotive executives want to talk about the "Art of the Possible" in analytics. So we took the opportunity to invite leaders around the industry to an Automotive Analytics Executive Roundtable to share their stories and spark new ideas.
