Given a set of N points in k-dimensional space, can you find the location that minimizes the sum of the distances to the points? The location that minimizes the distances is called the geometric median of the points. For univariate data, the "points" are merely a set of numbers $${p_1,
This July I'm refreshing the previous Strengthening Your Relationship email series from 2021. The email series offers quick ideas and information within three categories: research and insight, questions for closeness, and weekend activity ideas. As I revisit this content I was reminded of the weekly meeting practice I wrote about

SAS SVP Kimberly May provides a Q2 update about SAS Technical Support.
Amidst the ever-evolving retail industry landscape, marked by unprecedented challenges, one burning question emerges: What does it take to be a game changer in the face of disruption? Earlier this year, I was pleased to present the SAS Customer Experience “Game Changer Award” at the Retail Week Awards in London.
While writing an article about labeling a polygon by using the centroid, I almost made a false claim about the centroid. I almost claimed that that the centroid is the point in a polygon that minimizes the sum of the distances to the vertices. It is not. The point that
AI – just like humans – can carry biases. Unchecked bias can perpetuate power imbalances and marginalize vulnerable communities. Recognizing the potential for bias is one of the first steps toward responsible innovation. Doing so allows users to include diverse needs and perspectives in building inclusive and robust products. Through
Health care and life science organizations have always prioritized saving lives and now extend that commitment to environmental, social and governance (ESG) goals. They are not merely checking boxes, but genuinely pursuing long term impact for individuals, future generations and the planet. However, they must now elevate their ESG efforts to
A colleague asked how to compute the barycentric coordinates of a point inside a triangle. Given a triangle in the plane with vertices p1, p2, and p3, every point in the triangle can be represented as a convex combination of the vertices: c1*p1 + c2*p2 + c3*p3, where c1,c2,c3 ≥
SAS' Phuong Ngo demonstrates an automated shift-left CI/CD security workflow.
Part of the power of the SAS ODS system is the ability to visualize data by using ODS templates. An ODS template describes how to render data as a table or as a graph. A lot of papers and documentation have been written about how to define a custom template
Each color of the rainbow – red, orange, yellow, green, blue and purple – provides a unique set of nutrients and health benefits that allow our bodies to function more optimally. As we continue to work our way through the rainbow in this occasional series, let’s go for green. Remember, our
While writing an article about Toeplitz matrices, I saw an interesting fact about the eigenvalues of tridiagonal Toeplitz matrices on Nick Higham's blog. Recall that a Toeplitz matrix is a banded matrix that is constant along each diagonal. A tridiagonal Toeplitz matrix is zero except for the main diagonal, the
At SAS, where you start doesn’t have to be where you end; and there’s ample opportunity for internal career mobility. Milena Vukasovic has experienced this firsthand, and recently moved into a new role at SAS as a Sr. Associate Implementation Project Manager. Meet Milena Milena’s SAS story began at our
Entries are in. Now it’s your turn to cast your vote for the best in each category.
A Toeplitz matrix is a banded matrix. You can construct it by specifying the parameters that are constant along each diagonal, including sub- and super-diagonals. For a square N x N matrix, there is one main diagonal, N-1 sub-diagonals, and N-1 super-diagonals, for a total of 2N-1 parameters. In statistics and applied
What if, 12 months ago, someone bet you that a technology was coming in the next year that would cause great excitement and great fear in all businesses, industries and geographies? Would you have taken that bet? Of course, now we know that the technology is generative AI. Popularized by
SAS is known for providing an excellent customer experience. To continue that trend, we are currently modernizing our customer portal. This new system is scheduled to be in place by the end of the third quarter. In this blog, we want to give you a brief overview of what to
A previous article explains the Spearman rank correlation, which is a robust cousin to the more familiar Pearson correlation. I've also discussed why you might want to use rank correlation, and how to interpret the strength of a rank correlation. This article gives a short example that helps you to
Since the COVID-19 pandemic began, video presentations and webcasts have become a regular routine for many of us. On days that I will be using my webcam, I wear a solid-color shirt. If I don't plan to be on camera, I can wear a pinstripe Oxford shirt. Why the difference?
The analytics are mind boggling. But the story isn’t analytics. The designs will wow you. But the story isn’t design. The story, as it has been in each of the past 10 years, is that these amazing analytical designs sprang from the minds of students – North Carolina State University
As organizations embrace AI, they often handle large volumes of data that power AI systems. Handling data appropriately includes implementing adequate privacy policies and security measures to protect it. Doing so prevents accidental exposure and ensures ethical data use. AI technology often uses sensitive data for creating, training and utilizing models.
SAS expert Leonid Batkhan presents the %embed macro function as a way to embed both “foreign” and SAS native code from a file into a SAS program, preventing clutter in your code.
Did you know that over 300 people die daily from drug overdoses in the US? As a pharmacist, I have witnessed the harrowing effects of substance use disorder (SUD) and the resulting opioid crisis on individuals, families and communities. The complexity of addiction Who among us does not know someone
Welcome to the continuation of my series Getting Started with Python Integration to SAS Viya. In this post I'll discuss how to load multiple CSV files into memory as a single table using the loadTable action. Load and prepare data on the CAS server To start, we need to create multiple
Real-world data often exhibits extreme skewness. It is not unusual to have data span many orders of magnitude. Classic examples are the distributions of incomes (impoverished and billionaires) and population sizes (small countries and populous nations). The readership of books and blog posts show a similar distribution, which is sometimes
