A SAS customer asked a great question: "I have parameter estimates for a logistic regression model that I computed by using multiple imputations. How do I use these parameter estimates to score new observations and to visualize the model? PROC LOGISTIC can do the computation I want, but how do
Editor's note: This blog post is part of a series of posts, originally published here by our partner News Literacy Project, exploring the role of data in understanding our world. As discussed in previous posts, statistics and visual representations of data can be misleading. But what happens when the data itself is misleading? And if data is
A note from Udo Sglavo: A wealth of connectivity is pervasive in the data we gather across many industries. In other words, networks are all around us. A data science trend you cannot ignore is to organize, learn from, and drive decision-making based on connected data. Network analytics engines provide efficient
I believe the most important part of the analytics lifecycle is defining the business question being asked.
Most games of skill are transitive. If Player A wins against Player B and Player B wins against Player C, then you expect Player A to win against Player C, should they play. Because of this, you can rank the players: A > B > C Interestingly, not all games

In football, five out of the 11 players on offense are on the field to accomplish one goal: keep the defenders as far away from the ball as possible. Sometimes it’s more than five. Teams will bring extra linemen on short-play packages. Tight ends and full backs might check in
SAS' Sandy Gibbs kicks off a series of posts on hot fixes for SAS®9 environments.
It’s been a few years since I read Priya Parker’s The Art of Gathering, but it continues to inspire me to think about purposefulness in relation to gathering. A good gathering, a good friendship, a good relationship; all are going to be the product of mindful and purposeful effort. As
What comes to mind when you think of a “homeless person”? Chances are, you’ll picture an adult, probably male, dirty, likely with some health conditions, including a mental illness. Few of us would immediately recall homeless individuals as family members, neighbors, co-workers and other loved ones. Fewer still are likely aware of how many youths (both minors and young adults) experience homelessness annually. Homeless youth is a population who can
It’s no surprise that nonprofit organizations providing health-related services are overconsumed during the COVID-19 pandemic, but what about other types of nonprofits? According to CNM President and CEO, Tina Weinfurther, the pandemic has affected nonprofits in different ways. Some are running on fumes, while others have doubled in size and
I previously showed how to create a decile calibration plot for a logistic regression model in SAS. A decile calibration plot (or "decile plot," for short) is used in some fields to visualize agreement between the data and a regression model. It can be used to diagnose an incorrectly specified
Most New Yorkers like to fantasize about owning and living in a classic New York City brownstone, complete with high ceilings, large windows and a front stoop. You can picture yourself sitting there alongside the iron railing with a cup of coffee while you watch the city wake up and
The following is an excerpt from Cautionary Tales in Designed Experiments by David Salsburg. This book is available to download for free from SAS Press. The book aims to explain statistical design of experiments (DOE) to readers with minimal mathematical knowledge and skills. In this excerpt, you will learn about
If you’re like me and the rest of the conference team, you’ve probably attended more virtual events this year than you ever thought possible. You can see the general evolution of virtual events by watching the early ones from April or May and compare them to the recent ones. We
Recently nine pharmacists from across the country were charged for their part in a $12.1M health care fraud scheme. The pharmacists allegedly took money for prescription medications that were neither purchased nor dispensed. The indictments further allege that the defendants billed Medicare and Medicaid for medications that were often medically unnecessary and for some medications that were purportedly dispensed to
You look to the cloud for several reasons – to meet your cloud-first strategy, for scalability or to adapt quickly to changing business demands. Maybe all three. Perhaps you need offerings to be available in various regions, or to reduce application response time and improve latency problems. Perhaps regulatory and compliance constraints are limiting (or mandating) the physical locations where your data can be stored and transmitted. This is why having a global data footprint is
“It doesn’t stop being magic just because you know how it works.” Terry Pratchett, The Discworld Series Welcome to the third, and final, installment of Data Science in the Wild. In Part 1 we were lost in the woods thinking about how to start a data science project. In Part
Machine learning and visualisation help - 250 students enrolled in the program across all years. Now the program started its third year ...
The story goes on to the tune of 90 percent of available data today has been created in the last two years! As SAS (and the computing world) moves to the cloud, the question of, "How do I deal with my data (Big and otherwise), which used to be on-prem,
It's easy to get distracted by new developments in the fight against healthcare fraud. New services. New providers. Relaxation of rules. The COVID-19 pandemic has quickly revolutionized the healthcare landscape. For instance, the government made sweeping regulatory changes to accommodate a surge in patients. Healthcare delivery and payment organizations, commercial
Conversational AI can offer a way to provide that always-on 24/7, fast, convenient experience that can go anywhere (phone, computer smart speakers, even your car). It can provide a human-like experience through real-time, personalized interaction with AI running in the background. This technology is being applied across many industries for a variety of use cases (both customer-facing and for internal use).

We’ve all heard that we need to eat more plant foods, but what is it about plant foods that make them so good for us? Plants foods have many benefits, but beyond their fiber, vitamin and mineral content is their amazing and powerful polyphenol content.
Today’s customer really expects a truly extraordinary customer experience. That means that your company, your brand and the experiences you provide are not just in competition with people in your category. They’re in competition with people like Amazon, Uber and Starbucks, who have managed to make the mobile device a
To help visualize regression models, SAS provides the EFFECTPLOT statement in several regression procedures and in PROC PLM, which is a general-purpose procedure for post-fitting analysis of linear models. When scoring and visualizing a model, it is important to use reasonable combinations of the explanatory variables for the visualization. When
Bribery and corruption continue to plague governments and organizations around the world. Brazil’s Operation Car Wash, the 1MDB scandal in Malaysia, the FIFA bribery case and many others continue to make headlines. The prevalence of widespread, coordinated corruption and bribery is alarming and seems to continue to grow, despite ongoing sanctions and fines meant to deter these

If a cinderblock falls from the 4th floor of a building and crushes a construction worker’s foot, it’s terrible. If it lands on his head, it’s truly tragic. But the difference is sheer luck. Every employee deserves to return home safely from work. Unfortunately, accidents happen, which is why employers must carry mandatory workers’ compensation
As the COVID-19 virus jetted to pandemic status, folks around the company, including Carlos, were tapped to come up with data-driven solutions – fast. “Until we have a vaccine, one of the most effective ways to curb the spread of COVID-19 is by implementing Nonpharmaceutical Interventions, called ‘NPIs’,” Carlos explained.
