Perhaps you're a big data expert who is fluent in Pig, Hive, MapR and all the technologies associated with the open source big data framework. Or maybe your role hasn't yet been touched by the increasingly popular Hadoop system. It's certainly worth a few minutes of your time (or perhaps
David Loshin defines reference data and sets up a working definition for his next set of posts.
We’re not sure about you, but we just had the most thrilling, suspenseful, and fun month we’ve had in a while. The 2014 FIFA World Cup may be over, but we’re still amazed by not only the game outcomes and level of athleticism, but also by the wealth of interesting
In a previous blog post, I described how to generate combinations in SAS by using the ALLCOMB function in SAS/IML software. The ALLCOMB function in Base SAS is the equivalent function for DATA step programmers. Recall that a combination is a unique arrangement of k elements chosen from a set
When I started working at business analytics leader SAS, I had no idea I’d be helping the Great Britain Rowing Team plot their way to Olympic glory. While I haven’t, yet, got in a boat and started rowing, I have started working with them on how they can make better
In this blog post, I put some classic rock song data under the SAS Analytics microscope, to see if I could get a better picture of exactly what is considered 'classic rock' these days... Michael Raithel recently pointed me to an interesting article/study about 'classic rock' music, and invited (or is
Las estrategias para cometer fraude se están volviendo cada vez más sofisticadas al punto de hacerlo más difícil de detectar. Según la Agencia Fiscal Belga, se calcula que los delincuentes roban 100.000 millones de euros (132.000 millones de dólares estadounidenses) al año a los gobiernos de toda Europa mediante un
This week’s author tip is from Michele Burlew and her new book SAS Macro Programming Made Easy, Third Edition. Burlew chose this tip because she says it’s important to understand how SAS determines where a macro variable reference starts and stops, and often a delimiter is needed to tell SAS
Imagine if your ability to feed your family depended upon how fast you could run. Imagine the aisles of your grocery store as lanes on a running track. If you can outrun your fellow shoppers, grab food off the shelves and race through the checkout at the finish line, then
IT folks love SQL (Standard Query Language). Once you know how to program in SQL, you can work with almost any database because it is a standard. However, SQL is NOT a standard for doing analytics. The SAS programming language pre-dates SQL and even though SAS does SQL, SQL does not
In a previous blog post, I showed how to overlay a prediction ellipse on a scatter plot in SAS by using the ELLIPSE statement in PROC SGPLOT. The ELLIPSE statement draws the ellipse by using a standard technique that assumes the sample is bivariate normal. Today's article describes the technique
The sun has gone eerily quiet, in the middle of what should be the height of the 11-year sunspot cycle... Here's a superb photo of some sunspots that Stephen A. Carr posted to the Telescope Addicts Facebook group - a group which I follow with great interest. (Thanks for allowing
I had the privilege of attending the inaugural Women in Hollywood IT Society (WHITS) meeting this past week in LA. The meeting was hosted by the Media and Entertainment Services Alliance (MESA) with lots of organization from two female IT executives from Sony Pictures. Sony Pictures already has a Women
Although I’m not particularly excited about football (I admit, I don’t completely understand what offside means), I did follow the last World Cup with more than average attention. Not only for the handsome players, but especially for all the fascinating statistics that appeared. It struck me that heat maps popped
I’ve been told I have rocks for brains before, but right now I have rocks on the brain – the kind that are millions of years old and contain precious stores of oil and gas. One reason I have petroleum on my mind is that I’ve just returned from Brazil, where
For 38 years, SAS CEO Jim Goodnight has run this company by a simple philosophy: Treat employees like they make a difference and they will. It was with that philosophy in mind 30 years ago that SAS opened the doors to its on-site healthcare center – with just one employee!
If you recognize this 1984 Wham! hit then you also recall girls in ties and blazers, guys in leisure suits, gas for $1.10 a gallon and seeing The Karate Kid at the Cineplex for $2.50 (at night!). If you think music and fashion were suspect thirty years ago, consider SAS’
It is common in statistical graphics to overlay a prediction ellipse on a scatter plot. This article describes two easy ways to overlay prediction ellipses on a scatter plot by using SAS software. It also describes how to overlay multiple prediction ellipses for subpopulations. What is a prediction ellipse? A
In the summer heat, when The BFD alone isn't quite quenching your thirst for forecasting know-how, here are several other sources: CatchBlog -- by Steve Morlidge of CatchBull From his 2010 book Future Ready (co-authored with Steve Player), to his recent 4-part series in Foresight dealing with the "avoidability" of forecast
SAS is great at helping make important business decisions - how about helping decide where to take your next vacation?... Here's a picture from one of my favorite vacations with my buddy Joe. As you can see, I like "nature vacations." Can you guess where this one was? (leave a comment with
An empty matrix is a matrix that has zero rows and zero columns. At first "empty matrix" sounds like an oxymoron, but when programming in a matrix language such as SAS/IML, empty matrices arise surprisingly often. Sometimes empty matrices occur because of a typographical error in your program. If you
What is your primary goal as a supply chain professional? It’s not about demand sensing, demand shaping or even supply planning and demand planning. At the end of the day, it’s about profit optimization. Albeit important, demand sensing and shaping are only a piece of the equation and if isolated, decisions
When it comes to e-mail-based newsletters, I'm of two minds. On one hand, I feel like I receive enough (or maybe too much) e-mail and I'm reluctant to clog up my inbox with more stuff -- especially if it's information that's located elsewhere (such as on that big backup drive
This week’s author tip is from Matthew Gillingham and his new book SAS Programming with Medicare Administrative Data. Gillingham has been programming in SAS for 15 years and has spent 10 of those years specifically dealing with health care use, cost and quality measurement. Here’s Gillingham’s tip for you: To
Los datos importan más que nunca. Las organizaciones en progreso como Netflix y La Universidad de Texas, entre otras, están usando herramientas de visualización de datos para encontrarle forma a las grandes cantidades de información que se generan diariamente. En el libro The visual organization, Phil Simon, reconocido experto en
In my previous post, I examined ethics in a data-driven world with an example of how Facebook experiments on its users. Acknowledging the conundrum facing users of free services like Facebook, Phil Simon commented that “users and customers aren’t the same thing. Maybe users are there to be, you know... used.” What about when a
While managing quality within the four walls of your own operation is all well and good and totally necessary, both the market and your bottom line are demanding a more holistic, quality lifecycle approach, and in support of that aim there is a treasure trove of downstream data waiting to be
Have you written a SAS/IML program that you think is particularly clever? Are you the proud author of SAS/IML functions that extend the functionality of SAS software? You've worked hard to develop, debug, and test your program, so why not share it with others? There is now a location for
Again this year (for the 12th time), SAS Research & Development has funded two $5,000 research grants, to be awarded by the International Institute of Forecasters. Criteria for award of the grant will include likely impact on forecasting methods and business applications. Consideration will be given to new researchers in
This was probably my favorite of the myth-busters webcasts I have been spewing about, and now I definitely want to meet James Dallas so we can discuss and nod emphatically at each other’s insights on this topic! The “You can’t have analytics without IT” myth is the fourth myth covered
