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.
The birthday-matching problem (also called the birthday paradox or simply the birthday problem), is a classic problem in probability. Simply stated, the birthday-matching problem asks, "If there are N people in a room, what is the chance that two of them have the same birthday?" The problem is sometimes called
The 23rd annual SAS Championship has come to a close, and it proved to be another year of remarkable events. Employees, executives, customers and members of the community were able to join in on the fun in a variety of settings throughout the week. The events kicked off with the
The 10th Annual SAS Championship Women's Day event offered new inspiration to act with mindful intention and stay the course in life and career. An undeniable energy filled the Prestonwood Country Club ballroom on Tuesday, Oct. 10 as more than 230 attendees – mostly women – spilled into the room
In the first of a two-part series, SAS' Cindy Wang shows you how to create a radar chart in SAS Visual Analytics using custom graph capabilities.
Recently, we sat down with Jakob Koziel, Senior Research Analyst at Bissell Centre. During their conversation, Jakob highlighted some of the work Bissell Centre is doing to eradicate poverty in Edmonton and how SAS is helping them move their mission forward. Question: Give me a little bit of background on
The extreme temperatures that hit the UK in 2022 – the heatwaves of the summer followed by cold snaps in winter – were a reminder that the climate is becoming increasingly volatile. Globally, the weather conditions were even more challenging, with droughts, famines, wildfires, flooding, and hurricanes reported worldwide. All
Can you imagine a world where Medicaid isn’t just a lifeline for those in need but a force driving outcomes that transform lives? That vision is no longer a distant dream; it’s a reality that demands our attention. Medicaid programs make thousands of policy decisions each year that affect some
For another year, multiple golf teams from Historically Black Colleges and Universities (HBCUs) across the United States gathered in Cary, NC for the SAS HBCU Invitational Tournament. The tournament was part of the SAS Championship, a week-long event filled with networking, fun and golf. As part of the event, 16
Across a wide variety of industries, SAS users are leaning into the power of data to glean relevant insights and identify new opportunities. Through analytics, they are solving complex problems, discovering practical insights, and making a difference in their fields and communities. How can others join their efforts and use
Recently I wrote about numerical analysis problem: the accurate computation of log(1+x) when x is close to 0. A naive computation of log(1+x) loses accuracy if you call the LOG function, which is why the SAS language provides the built-in LOG1PX for this computation. In addition, I showed that you
The world’s largest rugby tournament returns for the knockout stages. This blog post explores how probability and simulation can be used to predict likely winners in each of the knockout stages. Team sports are dynamic, time-varying and complex topics to model. When modeling regular competitions, such as domestic leagues, it
