If you read this previous blog about types of salt (sodium chloride), you might recall that I mentioned salt is an essential nutrient. The body uses salt to maintain fluid levels and support muscle and nerve function. Sodium is critical for heart, liver and kidney function. Chloride, the other part
A profile plot is a way to display multivariate values for many subjects. The optimal linear profile plot was introduced by John Hartigan in his book Clustering Algorithms (1975). In Michael Friendly's book (SAS System for Statistical Graphics, 1991), Friendly shows how to construct an optimal linear profile by using
A profile plot is a compact way to visualize many variables for a set of subjects. It enables you to investigate which subjects are similar to or different from other subjects. Visually, a profile plot can take many forms. This article shows several profile plots: a line plot of the
Scammers and fraudsters love these 8 terms. Learn what they mean so you won’t be a victim.
In the public sector, agencies and organizations are increasingly using analytics to prioritize and plan their activities. In a sector characterized by the need to get value for money for the public, and often with limited resources, using data-driven work processes is essential. The NVWA, Dutch Food and Consumer Product
SAS® Fast-KPCA implementation bypasses the limitations of exact KPCA methods. SAS® internally uses k-means to find a representative sample of a subset of points. This row reduction method has the advantage that c centroids are chosen to minimize the variation of points nearest to each centroid and maximize the variation to the other cluster centroids. In some cases, the downstream effect of using k-means on computing the SVD increases numerical stability and improves clustering, discrimination, and classification.
More digital channels are bringing greater connectivity and more data is bringing added complexity to organizations. All this can feel chaotic or like a fog of information warfare. As a result, the pace of disruption and data expansion require visual tools that accelerate data wrangling and modeling. To overcome complexity,
Should you be using table salt, sea salt or kosher salt to season your food? Which is better? There are all kinds of options for salt these days, but are they really that different?
In this SAS administration tutorial Leonid Batkhan presents various SAS programming solutions on how to identify and prevent duplicate LIBREFs in SAS 9 metadata.
Many EU institutions are discovering the benefits of analytics to support policy decisions. But ultimately, no one has more potential to enrich output quality than policymakers themselves. Therefore, the entire organization must understand AI and analytics well. We call this the democratization of AI, bringing together the ideas of data
SAS' Yogender Kushawah introduces you to mining long sequences efficiently using the seqmc action in SAS Visual Analytics.
I recently blogged about how to compute the area of the convex hull of a set of planar points. This article discusses the expected value of the area of the convex hull for n random uniform points in the unit square. The article introduces an exact formula (due to Buchta,
Higher Education has been slow to adopt analytics in comparison to the commercial sector, but those institutions that have embraced a culture of analytics have seen significant and tangible results. Higher Education analytics can help in nearly every corner of academia including enrollment and retention, student success, academic research and
Joseph Castle offers some important considerations that will help you when building and working in an OSS community.
Childbirth should be a safe and joyous occasion as parents welcome a new member into their family. Still, too often, that joy is overshadowed by maternal complications, including maternal and infant death. Each year in the United States, as many as 60,000 women experience severe, unexpected health problems related to
Okay, I know what you’re thinking, protective eyewear is not the latest trend hitting the runway this Fall! But perhaps it should be. Did you know that 90% of the eye injuries each year (over 2.5 million world wide per the American Academy of Ophthalmology) could be prevented with protective
The area of a convex hull enables you to estimate the area of a compact region from a set of discrete observations. For example, a biologist might have multiple sightings of a wolf pack and want to use the convex hull to estimate the area of the wolves' territory. A
For many countries, their plan for the future focuses on a transition to a smart jobs economy. And for many organisations, the key to thriving in an innovative jobs economy centres on bringing talented individuals—with a particular focus on technology—and connecting them with roles that best utilise their talents. Talent
SAS' Bahar Biller and Xi Jiang use the example of a semiconductor manufacturing plant to illustrate the role of sensitivity analysis in assessing supply chain risk.
SAS SQL handles missing values differently than the ANSI standard for SQL. PROC SQL follows the SAS convention for handling missing values: numerical missing values are always interpreted as less or smaller than all nonmissing values. My first blog showed that missing values can be troublemakers in non-grouped descriptive statistics.
Every year, I write a special article for Halloween in which I show a SAS programming TRICK that is a real TREAT! This year, the trick is to concatenate two strings into a single string in a way that guarantees you can always recover the original strings. I learned this
With dynamically changing revenue streams, critical infrastructure needs and current higher-than-average gas prices and inflation concerns, transportation agencies around the country are using data to enable analytically driven decisions while navigating complex business challenges. Today's transportation industry is ripe with opportunities for innovation and growth. And this is especially true
I will show you how to deploy multi-stage deep learning (DL) models in SAS Event Stream Processing (ESP) and leverage ESP on Edge via Docker containers to identify events of interest.
Fraud detection is becoming increasingly more complex. Customers are demanding a frictionless consumer experience. Luckily, SAS' advanced machine learning models can better prevent fraud and protect customers by analyzing behaviors and detecting suspicious patterns in real-time.
Question: This neuroscientist and SAS Explore host is known for appearing on "Blossom," "The Big Bang Theory" and "Jeopardy." Answer: Who is Mayim Bialik, Ph.D.? Today, instead of Bialik quizzing us, I got to be the lucky one to quiz her on some of her favorite topics, like mental health,
Liv Boeree answers our questions about the game of poker – and life.
Shopping at an Asian grocery store can be intimidating. Hopefully the fruits and vegetables guide has helped you gain some confidence in navigating Asian markets. As you continue to explore and expand your selections, try these pantry essentials and snacks.
A SAS programmer asked how to create a graph that shows whether missing values in one variable are associated with certain values of another variable. For example, a patient who is supposed to monitor his blood glucose daily might have more missing measurements near holidays and in the summer months
Many businesses across the United Kingdom (UK) face price increases, cutbacks, or potential closures as they grapple with rising energy costs. The utilities market is facing its biggest challenge. It is set to be under scrutiny for a long time - with a supply shortage, inflation, rising demand and the
Did you know some scientists theorize that lions and tigers can hypnotize their prey using infrasound in their growl? You don’t hear it, but you feel it in your gut. That is exactly the level of intensity you feel coming off Oz Perlman in waves if you catch a show
