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
Cast your vote by Friday, Feb. 2 to determine winners of the 2024 SAS Customer Recognition Awards.
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
Learn how to fit a logistic regression and use your model to score new data. In part 4 of this series, we created and saved our modeling data set with all our updates from imputing missing values and assigning rows to training and validation data. Now we will use this
Did you know that 75-90% of visits to a health practitioner are related to stress? We all experience stress and not all stress is bad. Short-term stress helps us be motivated, but when it becomes chronic it can take a toll on our health and our quality of life. In
Composable, packaged, unbundled, traditional, reverse ETL, zero copy – these are just a few of the terms used to describe customer data platforms (CDPs) today. If you find that understanding the CDP marketspace is a bit like trying to discern meaning from a word salad (defined by Merriam-Webster as “a
The cold of winter and holiday gatherings push people indoors, causing a surge in influenza hospitalizations. Years of above-normal temperatures in southern states bring a species of mosquito that carries malaria to the US. Declining childhood immunization rates threaten to allow previously eradicated diseases like measles to become endemic again.
Statistical software provides methods to simulate independent random variates from continuous and discrete distributions. For example, in the SAS DATA step, you can use the RAND function to simulate variates from continuous distributions (such as the normal or lognormal distributions) or from discrete distributions (such as the Bernoulli or Poisson).
Well, it’s finally happening. After years of banter, Google began testing a feature called Tracking Protection on Jan. 4. This feature is designed to limit cross-site tracking via third-party cookies. It will be rolled out initially to 1% of all Chrome users, about 30 million people globally, with all users
Electrolyte drinks (think Gatorade and Powerade) have been marketed to athletes for decades, but in the last few years electrolyte water, powder, drops and tablets have become all the rage. With electrolyte replacement options galore on the store shelves, you may be wondering if you should be taking them. There’s
In a previous article, I presented some of the most popular blog posts from 2023. The popular articles tend to discuss elementary topics that have broad appeal. However, I also wrote many technical articles about advanced topics. The following articles didn't make the Top 10 list, but they deserve a
Where can you meet an iconic Silicon Valley reporter, a best-selling business book author, an experienced AI policy executive, a chief decision scientist from Google and a YouTube hot sauce sensation? All in one place? At our upcoming SAS Innovate event in Las Vegas, of course. SAS Innovate is the
Artificial intelligence (AI) is revolutionizing the way medical professionals deliver care and manage patient data. By harnessing the power of advanced algorithms and machine learning, AI applications contribute to more accurate diagnostics, personalized treatment plans and streamlined administrative processes. The integration of AI into health care is helping create a
An unobserved category is one that does not appear in a sample of data. For example, in a small sample of US voters, you are likely to observe members of the major political parties, but less likely to observe members of minor or fringe parties. This can cause a headache
Many executives may be feeling supply chain anxiety. The pace of disruptions – weather events, aggressive marketing techniques, transportation bottlenecks, and more – remains high, and there are already signs of consumer uncertainty in 2024. To manage the unknown and keep supply chains strong, some organizations are employing intelligent, real-time
It goes without saying that technology and interconnectedness has brought immense benefits to our lives, but it has also introduced new challenges, particularly for our seniors. One of the most prevalent and concerning issues faced by older adults is the threat of fraud. Seniors are often targeted due to perceived
Nurturing New Habits Do you run on autopilot? Many of us do. Because of this, it might take some effort to build new habits because it is easy to fall into default mode (aka Old Habits). This is certainly the time of year that resolutions and good intentions are born.
In 2023, I wrote 90 articles for The DO Loop blog. My most popular articles were about SAS programming, data visualization, and statistics. In addition, several "general interest" articles were popular, including my article for Pi Day and an article about AI chatbots. If you missed any of these articles,
