It is sometimes necessary for researchers to simulate data with thousands of variables. It is easy to simulate thousands of uncorrelated variables, but more difficult to simulate thousands of correlated variables. For that, you can generate a correlation matrix that has special properties, such as a Toeplitz matrix or a
Over the years, the US has drilled for crude oil in several locations, such as Pennsylvania, Texas, Alaska, and the Gulf of Mexico. A few years ago, as the US started drilling more in North Dakota, there were forecasts that we would surpass Saudi Arabia in crude oil production. And recently,
Once a disaster is over, and the frenzy of news stories and social media posts has subsided, it can seem like the crisis has passed. However, for those Hurricane Florence survivors left with ruined homes and businesses, damaged schools and buildings, there remains a struggle to return to normalcy. As
I often get asked for programming tips. Here, I share three of my favorite tips for beginners. Tip #1: COUNTC and CATS Functions Together The CATS function concatenates all of its arguments after it strips leading and trailing blanks. The COUNTC function counts characters. Together, they can let you operate
Jim Harris says learn the lineage of the data that fed the analysis before you get dazzled by visualizations or algorithms.
The solar farm at SAS world headquarters is a treasure trove of data. Jessica Peter, Senior User Experience Designer at SAS, had an idea about using that treasure in an art installation to show how data can tell a story. Her idea became a reality when she and others at SAS
Hearing someone talk about why they love their job is palatable when you have to make small talk at a cocktail party. But why spend your free time reading about why someone loves their job? Well, when you hear firsthand about how people are helping track endangered species using the
Programmers on a SAS discussion forum recently asked about the chi-square test for proportions as implemented in PROC FREQ in SAS. One person asked the basic question, "how do I test the null hypothesis that the observed proportions are equal to a set of known proportions?" Another person said that
About two-thirds of the way through her Analytics Experience presentation, Dr. Tricia Wang showed a video from Frans de Waal, a world-renowned primatologist. The video showed two monkeys receiving rewards for giving a researcher a rock. Each time a monkey handed over a rock it received a piece of cucumber.
The Grand Buddha at Ling Shan, located on the northern bank of Taihu Lake near Wuxi, China is a fitting metaphor for smart city initiatives in China, specifically Wuxi in the Jiangsu Province in Eastern China. One of the largest Buddha statues in the world, the bronze monument reaches 88
Continuation of Q&A from the September 19, 2018 ASA web lecture "Why Are Forecasts So Wrong? What Management Must Know About Forecasting." Why Are Forecasts So Wrong? Q&A (Part 2) Q: Should we make a distinction between business as usual forecasts and major change forecasts and do FVA for these
Last week I had the pleasure of delivering a one hour web lecture for the American Statistical Association on "Why Are Forecasts So Wrong? What Management Must Know About Forecasting." I find it helpful (both for myself and the audience) to follow up with written responses to all questions submitted
Move over salad, grain bowls have entered the room! Google ‘grain bowls’ and you’ll have a whopping 21,900,000 search results at your fingertips. Popular food trend? I’d say yes, and for good reason! Grain bowls are extremely versatile, quick to prepare, super satisfying and nutrient dense. They encourage mixing and
How to extract driving patterns by using smartphone sensors -- especially the accelerometer. With accelerometer readings in hand, you can use spectral analysis and other techniques to decompose events, and machine learning to match differentiate from patterns of risky drivers.
A radial basis function is a scalar function that depends on the distance to some point, called the center point, c. One popular radial basis function is the Gaussian kernel φ(x; c) = exp(-||x – c||2 / (2 σ2)), which uses the squared distance from a vector x to the
If you use SAS Visual Analytics and don’t have the SAS Visual Analytics app, you're missing out on a ton of convenience and interaction you could be having while on-the-go. This post outlines the app highlights.
David Loshin raises questions about what needs to be done to ensure quality analytics.
Here in North Carolina, a hurricane recently moved very slowly across our state, causing major flooding, and even closing miles of interstate highways for longer than a week. There is data available online for gauges along the river (or gages, as they call them), but I doubt many people know
Bold. Curious. Innovative. These words capture the spirit of our talented women in technology here, at SAS. That’s why we can hardly wait for the upcoming Grace Hopper Celebration – the largest gathering of women technologists – where we’ll join around 20,000 attendees to celebrate advancing women in technology!

Why is teaching and learning analytics so important? Recently, I interviewed two professors to gain their perspective on teaching students the skills they’ll need to pursue a lucrative career in the digital age. Joni Shreve, PhD, Faculty, Louisiana State University, explains: “We teach students analytics because there’s a talent gap
Last week I compared the overhand shuffle to the riffle shuffle. I used random operations to simulate both kinds of shuffles and then compared how well they mix cards. The article caused one my colleague and fellow blogger, Rob Pratt, to ask if I was familiar with a bit of
If you were to ask Tricia Wang, PhD, about real business growth, she would tell you that it lies outside the boundaries of the known. Not everything valuable is measurable, she would say. And big data is hiding new customers in the market from you. Wang is more than just
Do you want to insert blank rows into your TABULATE procedure tables? Here's a SAS sample and two other methods that will get the job done.
Referred to as the instigator of innovation, Mick Ebeling works to expand the human possibilities of technology through his company, Not Impossible Labs, whose mission is to change the world through technology and story.

I'm grinning as I type this post. I’m sitting in my office, sweaty from a run with a fan blowing in my face. Today, I have time to grab a shower later, but most days I don’t. I go from teaching to meeting with a client to covering our fitness
Every day I’m shufflin'. Shufflin', shufflin'. -- "Party Rock Anthem," LMFAO The most popular way to mix a deck of cards is the riffle shuffle, which separates the deck into two pieces and interleaves the cards from each piece. Besides being popular with card players, the riffle shuffle is
How can you use analytics to design better biopsies and improve outcomes? This high school student has some ideas, and she presented them at Analytics Experience 2018.
"We been through every kind of rain there is. Little bitty stingin' rain, and big ol' fat rain, rain that flew in sideways, and sometimes rain even seemed to come straight up from underneath." Was that a quote from the Forrest Gump movie, or something said regarding Hurricane Florence? Could be either one! Hurricane Florence recently came through
