When modeling and simulating data, it is important to be able to articulate the real-life statistical process that generates the data. Suppose a friend says to you, "I want to simulate two random correlated variables, X and Y." Usually this means that he wants data generated from a multivariate distribution,
Have you been in your attic lately? Or maybe cleaned out that closet that all of your “stuff” seems to gravitate to? Sure, mostly you’ll just find old junk that is no longer useful or purely nostalgic, but every once in a while you come across those long lost treasures
So you think you know how to forecast? Now is your chance to prove it, by participating in a probabilistic load forecasting competition run by my friend (and former SAS colleague), Dr. Tao Hong. Currently a professor at UNC Charlotte and director of the Big Data Energy Analytics Laboratory (BigDEAL),
Big data, by which most people mean Big Volume, doesn’t get you very far just by itself, but with the addition of Big Variety and analytics, now you’re talking. In fact, most organizations who are making headway into capitalizing on their data assets now refer to the process as "big
Do you ever stop and think about why it’s so hard to get really great customer service? As consumers, most of us are making transactions all day long, but it’s rare that someone actually surprises or delights us. More often, we rack up negative experiences. Think of what it’s like
Rick Wicklin created a nice example of using the SURFACEPLOTPARM statement to create a surface plot in SAS. As I read it, the question that immediately came to mind was: can I use this to create the famous SAS cowboy hat? The "cowboy hat" is a highly distributed example of
Customer intelligence will help an insurance company deepen its customer insights, choreograph its customer interactions and continuously improve its marketing performance. Unfortunately for all the progress made in recent years on customer relationship management and getting to know customers better, insurance companies are still not focusing on customers as much
Big data is here to stay, whether we like it or not. Regardless of how you feel about it, it can help solve problems which simply could not be addressed without big data and advanced analytics. One area in which big data and analytics can provide huge benefits is the medical arena. In a recent
This article shows how to visualize a surface in SAS. You can use the SURFACEPLOTPARM statement in the Graph Template Language (GTL) to create a surface plot. But don't worry, you don't need to know anything about GTL: just copy the code in this article and replace the names of
Imagine you're an investigator sorting through 6,000 mug shots taken at different jails around the state. You are tasked with finding all the mug shots of a high-profile con artist who has been arrested in multiple cities using a number of different aliases over the last five years. How can
The first text analytics product SAS released to the market in 2002 was SAS® Text Miner to enable SAS users to extract insights from unstructured data in addition to structured data. In 2009, in quick succession, SAS released two new products: SAS® Enterprise Content Categorization and SAS® Sentiment Analysis. These
The #1 rule of any self-respecting hipster is to not claim to be a hipster. Therefore, can there even be such a thing as a hipster beard, or hipster beard data? I contemplated this perplexing question, as I stroked my pirate beard. Since fashion trends tend to be cyclical, perhaps
with Natalie Osborn, Senior Industry Consultant, Hospitality and Gaming Practice, SAS We’ve taught analytics 101 through the last couple of blog posts, and now that you have passed that course, you are ready to take an advanced course in analytics. Ok, not really, we won’t subject you to that, but
Gartner has stated that there are nearly five billion connected devices throughout the world today and predicts that there will be more than 25 billion by 2020, making the potential of this technology unlimited. The connected devices in industrial settings, in personal devices, and in our homes are creating a
There are many ways to do data integration. Those include: Extract, transform and load (ETL) – which moves and transforms data (with some redundancy) from a source to a target. While ETL can be implemented (somewhat) in real time, it is usually executed at intervals (15 minutes, 30 minutes, 1
Though crude oil prices edged up last week, the market remains well below VirtualOil’s original $50 strike price, meaning the hypothetical portfolio’s production is shut in in the spot market again. Oversupply continues while China GDP forecasted growth is slowing. Given the market outlook, the VirtualOil board has decided to
This guest blog post comes from Dr. David Dickey, one of our original SAS Press authors. Hope you enjoy! In the late 1970s, shortly after SAS was founded, I was approached by Herbert Kirk and John Brocklebank from SAS to put together a course on time series. This was reasonably
Jim Harris addresses some of the most common questions and challenges big data poses for data quality.
“Our job at the lab is to find technology that’s new, cutting edge and cool – and to give it to someone else to be brilliant with.” – Matthew Horn, Manager, SAS Emerging Technologies UI Lab If you’ve heard of Google Glasses or Occulus Rift, you’ve heard of augmented reality.
Suppose that you are tabulating the eye colors of students in a small class (following Friendly, 1992). Depending upon the ethnic groups of these students, you might not observe any green-eyed students. How do you put a 0 into the table that summarizes the number of students who have each
I’ve often heard people say about weather forecasters “they have the best job…they just report what the models are telling them, and when they’re wrong they can always blame it on Mother Nature throwing us a curve.” While that’s true, this glass-half-empty crowd is failing to appreciate how amazing the
I remember being intrigued by the movie In Search of Noah's Ark, when I was a kid back in the 1970s. They claimed to have definitively found the ark ... but of course, since then several other people claim to have found it in other locations. Therefore I don't feel too
Following World War II, an intelligence-sharing partnership was formed between Australia, Canada, New Zealand, the United Kingdom and the United State of America. The original alliance, called Five Eyes, was focused on monitoring the communications of the major global threat at the time – the Soviet Union. As the world
I’m still old school enough to enjoy reading the local News & Observer on weekends. I even like flipping through pages that leave my fingers smudged from newsprint. I was reading an editorial piece a while back, and a phrase leapt out at me. A correspondent wrote, “We are in
Editor Len Tashman's Preview of the Fall 2015 issue of Foresight This 39th issue of Foresight features a special section on forecasting support systems (FSS) developed by our FSS Editor Fotios Petropoulos. His article Forecasting Support Systems: Ways Forward highlights three main areas for improvement: better utilization of open-source software
While holed up inside, like many others on the East Coast of the United States, suffering from record-breaking rainfall and watching the path of Hurricane Joaquin, I found a perfect metaphor for handling a problem in explaining analytics. Many executives bemoan the fact that it seems to take forever for
People encounter stress in all types of situations. Positive stress occurs when we are exposed to new situations or challenges, perhaps a new job or attending a new school – this type of stress is typically short term and is a necessary factor in healthy development. Tolerable stress results from
I hear a lot of talk about income inequality in the US ("the rich get richer..." and such) - especially as elections approach. I also see a lot of graphs, and they all seem to define their numbers slightly differently. I'm not in a position to improve the way income
You can use SAS to generate random integers between 1–10 or in the range 1–100. This article shows how to generate random integers as easily as Excel does. I was recently talking with some SAS customers and I was asked "Why can't SAS create an easy way to generate random
The Internet of Things (IoT) is a revolutionary approach that will radically change our lives, our way of integrating with technology, and the way we do business and marketing. Companies have already defined a strategic plan for collecting and organizing data coming from the IoT. The next step is to
