Note from Udo Sglavo on mathematical optimization: When data scientists look at the essence of analytics and wonder about their daily endeavor, it often comes down to supporting better decisions. Peter F. Drucker, the founder of modern management, stated: "Whenever you see a successful business, someone once made a courageous decision."
It's been a great ride Since 2014, the Operations Research Blog has covered a broad range of topics related to real applications of operations research. Paraphrasing Principal Product Manager for Optimization Ed Hughes' first post - this blog covered how OR methods could be applied to organizational and business planning
Does healthy eating on a budget seem out of reach? You might think you have to sacrifice good nutrition to keep your food finances in check, but thinking that way can be a justification for purchasing cheaper, highly-processed foods. Such foods marketed as complete meals or sides often contain little
One of the first things I learned in SAS was how to use PROC PRINT to display parts of a data set. I usually do not need to see all the data, so my favorite way to use PROC PRINT is to use the OBS= data set option to display
This is another in my series of blogs where I take a deep dive into converting a customized R graph into a SAS ODS Graphics graph. Can you guess what data I'll be using this time? Here's a photo with a hint. This is Keeler, California (just west of Death
One irony during this pandemic is that single people wish they were partnered and partnered people wish they were single. Today’s blog post is for the partnered people out there who are struggling with the increased stress and togetherness during this pandemic. I don’t need to tell you what
"With #HackinSAS, we want to build on the best of many young ideas into innovative products on one platform."
An UpSet plot is used to visualize intersections of sets. In this post, we will illustrate techniques to create this plot using the Graph Template Language (GTL). We assume that you are familiar with GTL. From the point of view of construction, we leverage the LATTICE layout available in GTL
Interview with Chief Digital Officer at SAMSON: Dr. Thorsten Pötter.
Go from gridlocked model development to accelerated innovation by moving to the cloud.
Look at the following matrices. Do you notice anything that these matrices have in common? If you noticed that the rows of each matrix are arithmetic progressions, good for you. For each row, there is a constant difference (also called the "increment") between adjacent elements. For these examples: In the
This is another in my series of blogs where I take a deep dive into converting a customized R graph into a SAS ODS Graphics graph. This time the example is a needle plot (that's essentially like a bar plot, with lots of tiny bars, plotted along a continuous xaxis).
In a previous article, I showed how to generate random points uniformly inside a d-dimensional sphere. In that article, I stated the following fact: If Y is drawn from the uncorrelated multivariate normal distribution, then S = Y / ||Y|| has the uniform distribution on the unit sphere. I was
In my position as an independent customer experience expert on the SAS Collaborators Programme, I’ve been delving into the detailed results and findings from its latest piece of CX research: Experience 2030: Has COVID-19 Created a New Kind of Customer? The exercise set out to discover how attitudes have changed,
Globus (Rouven Dörr) and DFKI (Frederic Kerber) tackle the big questions about the future of AI in supermarkets.
I previously blogged about the impact drafting offensive linemen has on winning and making the playoffs. Since I wrote that, we have new data points to add to the analysis and an exciting finale to this NFL season. In this blog post, I’ll explore a few more arguments both in
SAS Press author Kim Chantala shows you how to to spend less time preparing data so you can lavish time on analysis.
Imagine an animal that is searching for food in a vast environment where food is scarce. If no prey is nearby, the animal's senses (such as smell and sight) are useless. In that case, a reasonable search strategy is a random walk. The animal can choose a random direction, walk/swim/fly
The BIG Group can’t wait to gather in-person again, but for now, they’re staying safe and meeting virtually. We love this group portrait above of the Black Initiatives Group leadership council titled “An Evening of Excellence,” created by BIG co-chair Christopher Williams. __________________________________________________________________________________________ Our SAS culture blends our different backgrounds,
In conversation with Sophie Achermann, co-founder of the platform www.StophateSpeech.ch.
In the past, Sanjay showed how to create several basic graphs using both R and SAS ODS Graphics code. I'm going to take a bit of a "deeper dive" and focus a series of blog posts on highly customized graphs. Hopefully the code for these customizations will provide you with
Economic, tech and regulatory trends are shifting asset liability management strategies.
We’re proud of our unique company culture that spans across offices, divisions and geographies. It’s one of the reasons why SAS is named among the top workplaces in the world by Fortune’s Great Place to Work! If you’re curious about what it’s like to work at SAS, you’re in the right place. Our people are always asking, “What if?’ and pushing the bounds of

Little Miss Muffet Sat on a tuffet, Eating her curds and whey; Along came a spider, Who sat down beside her And frightened Miss Muffet away! I grew up chanting this popular nursery rhyme and now recite it to my children, but it wasn’t until I started making Greek
SAS' Leonid Batkhan encourages you to join him at SASensei, an independent, third-party online SAS learning resource (game).
The inverse gamma distribution is a continuous probability distribution that is used in Bayesian analysis and in some statistical models. The inverse gamma distribution is closely related to the gamma distribution. For any probability distribution, it is essential to know how to compute four functions: the PDF function, which returns
Safety, efficacy, speed and costs must all be prioritized and balanced in the delivery of life-changing therapies to patients. A drug that's quickly and cost-efficiently delivered to market, but isn’t effective and safe is unacceptable. An effective, safe drug that doesn’t get to patients in time to save lives has
Years ago, I wrote about how to compute the incomplete beta function in SAS. Recently, a SAS programmer asked about a similar function, called the incomplete gamma function. The incomplete gamma function is a "special function" that arises in applied math, physics, and statistics. You should not confuse the gamma
A note from Udo Sglavo: When people ask me what makes SAS unique in the area of analytics, I will mention the breadth of our analytic portfolio at some stage. In this blog series, we looked at several essential components of our analytical ecosystem already. It is about time to
