I read a journal article in which a researcher used a formula for the probability density function (PDF) of the sample correlation coefficient. The formula was rather complicated, and presented with no citation, so I was curious to learn more. I found the distribution for the correlation coefficient in the
In 2024, fraud and financial crimes are rising in global banking due to an evolving economic environment and expanding technological capabilities that create new opportunities for fraudsters. In 2023, consumer-focused fraud increased, with attackers posing as energy firms, lottery companies and banks to extract sensitive information from unsuspecting victims. Inflationary pressure saw

At SAS, we take a passionate stance in shaping the future of tech leaders. In 2023, we introduced the SAS HBCU+ Fellows Program, inviting faculty from Historically Black Colleges and Universities (HBCUs) and Primarily Black Institutions (PBIs) to gain hands-on experience with SAS and pass on this knowledge to their
Some hearts are famous. For example, there is the "Heart of Gold" (Neil Young), the "Heart of Glass" (Blondie), and the Heart of Darkness (Joseph Conrad). But have you heard of the "Heart of Ellipses"? No? Well, in 2023, Ted Conway published an amusingly titled article, "Total Ellipse of the
As nations gear up to transition to more intelligent job prospects, organisations seek to excel in pioneering job markets, particularly in the technology sector. Recognising and harnessing the talents of students is crucial for this to succeed. This means providing the right education, hands-on training, and mentorship from academic and
In 1990 I was a couple of years out of college, trying to support myself with multiple jobs, and navigating a relationship with a partner who could best be described as “non-committal”. I was also working in a domestic violence shelter and observing how often fear of being alone and
Large language models (LLMs) are at the forefront of today’s AI, not merely as technological marvels but as transformative agents reshaping how businesses innovate, operate and deliver value. Think of them as the wizards of words, capable of understanding language and transforming it in ways that benefit organizations. However, as
2023 was a momentous year for Technical Support! I wanted to share some of our achievements with you that demonstrate our commitment to providing you with excellent customer support. Customer Portal By far our biggest accomplishment was the launch of the new customer portal. To achieve this, Technical Support worked
This article looks at a geometric method for estimating the center of a multivariate point cloud. The method is known as convex-hull peeling. In two-dimensions, you can perform convex-hull peeling in SAS 9 by using the CVEXHULL function in SAS IML software. For higher dimensions, you can use the CONVEXHULL
Retailers face unprecedented challenges with supply chain volatility, inflation, oil price fluctuations, labor shortages and geopolitical activities, making it difficult to plan across the organization. With retail evolving, coupled with persistent supply chain issues, this adds complexity to anticipating and planning for shifts in consumer demand. The emergence of an
The National Institute of Standards and Technology (NIST) has released a set of standards and best practices within their AI Risk Management Framework for building responsible AI systems. NIST sits under the U.S. Department of Commerce and their mission is to promote innovation and industrial competitiveness. NIST offers a portfolio
A SAS programmer wanted to find the name of the variable for each row that contains the largest value. This task is useful for wide data sets in which each observation has several variables that are measured on the same scale. For example, each observation in the data might represent
Transitioning from SAS9 to SAS Viya can be uncertain for SAS programmers. Whether your organization is making the move and you’re curious about your current SAS analytical workflows, or you're contemplating moving to SAS Viya and concerned about its impact on your SAS expertise and programs. The hesitation is understandable.
Let me ask: did you believe Facebook CEO Mark Zuckerberg really boasted about the company’s power in a 2019 video, saying, “Imagine this for a second: One man, with total control of billions of people’s stolen data, all their secrets, their lives, their futures.” The video of Zuckerberg purportedly saying
In the digital age, the adage "knowledge is power" has evolved into "data is power." It reflects the immense value of high-quality data and a strategic approach to data management. At the heart of any successful modern enterprise lies a robust data strategy coupled with stringent data quality standards. For
Organizations continuously search for innovative ways to optimize their operations and elevate efficiency. One promising frontier is the integration of digital twins for predictive maintenance. However, the true potential of this technology often remains untapped, with many organizations settling for what can be described as “digital shadows.” In this exploration,
A colleague remarked that my recent article about using Jacobi's iterative method for solving a linear system of equations "seems like magic." Specifically, it seems like magic that you can solve a certain class of linear systems by using only matrix multiplication. For any initial guess, the iteration converges to
Use SAS DATA step to split a large binary file into smaller pieces, which can help with file upload operations,
If you’re looking to make movement a regular habit, then consider the F.I.T.T. principles of exercise. F.I.T.T. = Frequency, Intensity, Time, Type Frequency of exercise refers to the number of times per day or days per week you will add movement to your routine. Strategy: Many recommendations will suggest starting
I often think of the expression “Bend so you don’t break” when I need to remind myself to be flexible in my mindset. As a yoga enthusiast, it also makes good literal sense to be physically flexible. But what about metabolic flexibility? I think the saying applies here too. Being
In a first course in numerical analysis, students often encounter a simple iterative method for solving a linear system of equations, known as Jacobi's method (or Jacobi's iterative method). Although Jacobi's method is not used much in practice, it is introduced because it is easy to explain, easy to implement,
The realm of augmented reality and mixed reality (AR/MR) is on the brink of a significant evolution, promising to reshape how we engage with technology. Augmented reality involves the overlay of digital information onto the real world, enriching our perception of the environment by adding virtual elements. This technology enhances

There are two popular ways to express the steepness of a line or ray. The most-often used mathematical definition is from high-school math where the slope is defined as "rise over run." A second way is to report the angle of inclination to the horizontal, as introduced in basic trigonometry.
Have you ever been curious about your monthly water consumption and how it compares to others in your community? Recently, I had this question and decided to get ahold of my family's water usage data for analysis. Harnessing the power of data visualization, I compared my family of four's monthly
Now more than ever, as the lines blur between work and life, employee well-being affects how we thrive in our work and personal lives. At SAS, we believe that prioritizing the well-being of our people is the right thing to do for our employees, and it also makes sense from
Whether for better or for worse, many people agree that generative AI is a game changer that will revolutionize the way we live and work. Optimists believe that generative AI is an opportunity to improve and expand our technological knowledge. At the same time, catastrophists fear that AI in general
I saw a fascinating Reddit thread titled: "What would you do if your son told you he’s dating an AI?" Here's the post verbatim: "My son (20M) just told my wife and I that he’s been in a relationship with a replika for the past few months. He claims that it’s
