Biplots are two-dimensional plots that help to visualize relationships in high dimensional data. A previous article discusses how to interpret biplots for continuous variables. The biplot projects observations and variables onto the span of the first two principal components. The observations are plotted as markers; the variables are plotted as
This is an issue I hear about from parents all of the time. Sometimes the disagreements are small, and sometimes they are very significant. As your child ages, the stakes become even higher when parents can't get on the same page. Here are a few common ways that parents find themselves
The t-test is a very useful test that compares one variable (perhaps blood pressure) between two groups. T-tests are called t-tests because the test results are all based on t-values. T-values are an example of what statisticians call test statistics. A test statistic is a standardized value that is calculated
A major UK insurance company used text analytics to categorise complaints.
US military veterans are mission-focused, team-oriented and natural leaders that benefit any organization that hires them. Many of today's veterans organizations use data and analytics to help transition military members and their spouses find rewarding civilian careers. SAS supports those efforts and we're also proud to offer many programs to
Analyzing tweets is challenging because of their succinctness (max 280 characters). However, that task is facilitated by the powerful features of SAS Visual Text Analytics (VTA), which includes embedded machine learning algorithms.
I recently saw in several social media posts that sales of vinyl records are forecast to be higher than sales of CDs this year (2019) for the first time since 1986. Two questions came to mind - 1) Is this true? and 2) Is this a big deal? Let's analyze
It’s always worth trying to improve our world and if it can be done thanks to analytics - I can’t imagine a better use case.
In grade school, students learn how to round numbers to the nearest integer. In later years, students learn variations, such as rounding up and rounding down by using the greatest integer function and least integer function, respectively. My sister, who is an engineer, learned a rounding method that rounds half-integers
With all this sitting at a desk writing code, I have to do something to keep in shape. And for me, that something is paddling boats ... as fast as I can - and occasionally trying to race them. This past weekend I entered the race at Hunting Island, SC.
What precisely, then, is needed in risk management? Users want a user-friendly interface, so that they can find what they need.

“Let us remember: one book, one pen, one child, and one teacher can change the world." — Malala Yousafzei Growing up with dyslexia was a challenge but what I most clearly remember are the successes. I attribute much of this to my dad’s dedication to my education and reading skills.

Innovation comes in all shapes and sizes. Business value though, lies in translating ideas into production.
Principal component analysis (PCA) is an important tool for understanding relationships in continuous multivariate data. When the first two principal components (PCs) explain a significant portion of the variance in the data, you can visualize the data by projecting the observations onto the span of the first two PCs. In
If you know me, you know I’m not a shopper. Shopping stresses me out. I wish I had a uniform to put on for work so that I didn’t have to think about it, because life is stressful enough without adding stress. What I need to do is eliminate the
The public sector is finally changing. Artificial intelligence is gradually finding its way into its administrative structures.
At SAS, we recognize and appreciate the valuable skills and experience that veterans, active military and military families bring to our workforce.

According to the Price Waterhouse Cooper 2018 Global Economic Crime and Fraud Survey, the reported rate of economic crime is on the rise, up to 49% in 2018. That makes the use case I want to share particularly relevant, no matter what industry or sector you're in. This use case
Assessing a company from the outside can be tricky business – but it shouldn’t be. That’s why we’re pulling back the curtain on the #saslife. From our values to our vision and (almost) everything in between, we’re giving a transparent look at what it’s really like to work here. Our values aren’t
Understanding multivariate statistics requires mastery of high-dimensional geometry and concepts in linear algebra such as matrix factorizations, basis vectors, and linear subspaces. Graphs can help to summarize what a multivariate analysis is telling us about the data. This article looks at four graphs that are often part of a principal
#Amazon forced retailers to find new ways to attract their customers. How can artificial intelligence help #retailers to adress their group?
When I started working in data and analytics 30 years ago, information security wasn’t high on the agenda for organizations. That's changed with the rise of the Internet, and now that cloud is becoming more and more prevalent in organizations, information security is no longer just the domain of specialists
I was recently reading David Mintz's excellent SESUG 2018 conference paper on Five Crazy Good Visualizations and How to Plot Them, and saw a map that caught my eye. David showed how to create a similar map, but with completely different data - I decided to try creating a map
While growing up in the 80's, I watched The Golden Girls on TV with my Grandma Betty. Now, when my sister visits, we binge watch reruns on TV Land. I was excited when I saw for this Halloween, you could buy Golden Girls costumes! Too bad they sold out right
