Howard Wainer, who used to write the "Visual Revelations" column in Chance magazine, often reminded his readers that "we are almost never interested in seeing Alabama first" (2005, Graphic Discovery, p. 72). His comment is a reminder that when we plot data for a large number of categories (states, countries,
Stu Bradley discusses the importance of education, diligence and analytics in the fight against fraud.
K Nearest Neighbour is an algorithm that stores all the available observations and classifies the new data based on a similarity measure.
Inspiring discussions with Carla Harris and fellow executives in the heart of NYC. In October, leaders from SAS and other organizations in life sciences, health care, and health care-focused finance participated in a transformative leadership event. This experience left a lasting impression. The event was the kickoff of SAS’ first
What makes mainframes relevant today? Why are they still in use more than 50 years after their inception? Watch the video below and then come back to read about some specific use cases of SAS® technology in use on IBM mainframe computers. Mainframes have had many uses Throughout this half-century
By definition, managed services require a high degree of trust. After all, you’re paying someone else to manage your business applications and, in many cases, your data. To help establish that trust, we want to introduce you to our managed services team – and have them answer some of your
You most likely have used a Portable Document Format (PDF) file in one form or another. Now, what if you have a PDF file and want to extract the text from the file? What if the PDF file contains input fields that a user fills in and you want to
It seems like everyone is tired. Many of us are overcommitted, we don’t get enough sleep, we are stressed, and maybe we don’t eat the best either. Fatigue is beyond feeling tired. Most of the time if you are tired, and you get some good sleep, you will feel better.
Sometimes it is helpful to display a table of statistics directly on a graph. A simple example is displaying the number of observations and the mean or median on a histogram. In SAS, the term inset is used to describe a table that is displayed on a graph. This article
When it comes to my data in the cloud, I want my service providers to keep security in mind. Few things worry me more than knowing my private information is not secure, or is being shared with untrusted collaborators. That’s why the recent announcement from SAS, our partner Microsoft, and
Appending data tables is a common task for data analysis. Here are three of the several methods possible through the SAS Viya platform.
Every November, we celebrate Veterans Day and Military Family Appreciation month to honor the service and sacrifices that service members, veterans and military families make to keep our nation safe and protect our freedom. Join us in recognizing the amazing people at SAS who have served and continue to serve
In several previous articles, I've shown how to use SAS to fit models to data by using maximum likelihood estimation (MLE). However, I have not previously shown how to obtain standard errors for the estimates. This article combines two previous articles to show how to obtain MLE estimates and the
In a previous post, we explored the intricacies of panel data regression. We unveiled a range of panel models and demonstrated their application in estimating cigarette demand by using the CPANEL procedure. However, achieving reliable insights in the realm of panel data regression requires addressing practical challenges. These would include
I recently had two incredible opportunities: to visit the White House for a landmark executive order signing and to make remarks at a US Senate AI Insight Forum. The AI Insight Forum was part of a bipartisan Congressional effort to develop guardrails that ensure artificial intelligence is both transformative and
The ability to analyze and derive insights from vast amounts of information is invaluable. As industries increasingly rely on data-driven decision-making, there is a growing demand for professionals with expertise in applied analytics. To bridge this skills gap, academic institutions seek innovative ways to provide students with hands-on experience. Integrating
Today’s consumers don’t want to be talked to; they want to have a conversation. They want to be marketed to as individuals, not as faceless members of the masses. Consumer packaged goods (CPG) organizations, in particular, recognize the value of these conversations. This dialogue – via loyalty programs, promotions, social
Have you heard of Thai Yoga? It often gets confused with Tai Chi, but Thai Yoga is a modality of healing that is an Ayurvedic (Ancient Indian Medicine) tradition. During the time of Buddha, monks went to Thailand to set up temples and practiced healing arts which consisted of a
A previous article shows how to use Monte Carlo simulation to approximate the sampling distribution of the sample mean and sample median. When x ~ N(0,1) are normal data, the sample mean is also normal, and there are simple formulas for the expected value and the standard error of the
In today’s world of financial services, a well-crafted decisioning system is paramount, whether you're dealing with credit risk, fraud prevention, financial compliance, or any other critical aspect. Occasionally, financial services organizations decide whether to buy a risk decisioning system or build one using in-house resources. This quandary demands careful consideration
The relationship between trust and accountability is taking center stage in the global conversations around AI. Accountability and trust are two sides of the same coin. In a relationship – whether romantic, platonic or business, we trust each other to be honest and considerate. Trust is fueled by actions that showcase
Welcome back to my SAS Users blog series CAS Action! - a series on fundamentals. In this post, I'll show how to create user defined functions (UDFs) for the distributed CAS server using SAS and CASL code. Once the UDF is created, you can use it on the CAS server with programming
Much of the discussion around how to manage the advanced forms of artificial intelligence—machine learning, generative AI, large language models—deals with them only as technologies. This is a mistake. Like any employee, AI must be onboarded to learn "how we do things around here." Advanced forms of AI have characteristics
An elementary course in statistics often includes a discussion of the sampling distribution of a statistic. The canonical example is the sampling distribution of the sample mean. For samples of size n that are drawn from a normally distribution (X ~ N(μ, σ)), the sample mean is normally distributed as
In this era of technology dominated by AI and rapid advancements, trust has emerged as a critical pillar of our interconnected world. As Reggie Townsend, Vice President of the Data Ethics Practice at SAS, explains, we must understand that trust is essential for meaningful relationships and the functioning of civil
Did you know that approximately one in 28 children grows up with a parent behind bars? That’s not just a number – it’s a glimpse into the lives of young people who face this challenge and need support to break the cycle. According to the US Department of Health and
Chronic pain affects more than 30% of people worldwide; that’s billions of people that suffer every day. As defined by the International Association for the Study of Pain (IASP), chronic pain is pain that persists or recurs for more than 3 months. For many people, this type of pain is
A previous article discusses the birthday problem and its generalizations. The classic birthday problem asks, "In a room that contains N people, what is the probability that two or more people share a birthday?" The probability is much higher than you might think. For example, in a room that contains
The look. Anyone who has experienced a loss knows the look I am talking about. That flat smile of lips closed together. A sigh, sad eyes and tilted head. If you’ve recently experienced a death, that look greets you everywhere you go. Someone grieving recently told me it'd be nice
In the second of a two-part series, SAS' Cindy Wang reveals how to create a custom graph template in SAS Graph Builder that can be rendered as a radar chart in SAS Visual Analytics.
