I caught up with Jaimy van Dijk, one of our youngest female SAS Data Scientists who has proven herself to be a true Rockstar.
While I am a woman in computer science, let me start by saying that I’m a reluctant coder. I have an eye for data but find the abstract nature of many computer languages to be very challenging and not something I typically love. My first experience with coding was in
Fifty years ago, as the women’s liberation movement was gaining momentum in the U.S., my maternal great-grandmother, Pearl, worked in a factory sewing American flags while volunteering with the Girl Scouts and caring for her grandchildren. My paternal grandmother, Greta, also worked in local factories while caring for her family.
I'm a planner, and my plan was to have a completely natural birth and to breast feed only. This plan was written in stone (or so I thought). Long story short – my birthing plan flew out the window. One of my complications was very high blood pressure, which refused
SAS R&D's Brent Laster, a DevOps director, describes the ease and efficiency of switching SAS software on and off using containers.
There are many ways to add more "visual impact" to your maps. Some techniques grab the users' attention, but often don't add anything useful to the message the map is trying to convey (such as 3D tricks, or flashy/gratuitous images and infographics). I encourage you to design maps that have
What do a Pulitzer prize-winning author, an Emmy award-winning TV personality and one of the top 5 influencers in the world have in common? They’ll all be at SAS Global Forum this year. It’s where analytics enthusiasts and executive thought leaders meet to share strategies, get training in abundance, and
You can represent every number as a nearby integer plus a decimal. For example, 1.3 = 1 + 0.3. The integer is called the integer part of x, whereas the decimal is called the fractional part of x (or sometimes the decimal part of x). This representation is not unique.
Cancer touches nearly everyone. You probably know at least one person who's been diagnosed with cancer -- many of us know many more than one. It's the second leading cause of death worldwide, behind cardiovascular disease. World Cancer Day is observed this year on February 4, and is meant to
Almost everyone enjoys a good glass of wine after a long day, but did you ever stop to wonder how the exact bottle you're looking for makes its way to the grocery store shelf? Analytics has a lot to do with it, as SAS demonstrated to attendees at the National
We've made it to the halfway point of January, which means most of the industry's annual predictions have been published. Who's guessing what? And how should you prepare for the year ahead? From dark data to hyperpersonalization, analytics is at the core of all these predictions. SAS experts have been
The new method tackles the challenge of missing features under the multi-task learning framework. The proposed method is effective for prediction and model estimation when missing data is present.
"Why are we doing this?" No matter who you are, that’s a question you’ve likely asked yourself more than once. Whether as a child receiving instruction from your parents, or as adults contemplating the reason behind decisions made at work, we are curious by nature. We all carry this innate
Last year, I wrote more than 100 posts for The DO Loop blog. The most popular articles were about SAS programming tips for data analysis, statistical analysis, and data visualization. Here are the most popular articles from 2019 in each category. SAS programming tips Create training, testing, and validation data
SAS Model Studio lets modelers use SAS alongside open source to create and compare models in a pipeline and project. Debugging, model comparison, and visual pipelines are included.
From sports and health data to environmental and policy data, our data visualization experts have used SAS technologies to explore and present analyses on hundreds of topics throughout the year. We've selected some of the best in this end-of-year roundup to showcase their skills and SAS technologies, and to demonstrate
How can a solar farm ensure peak energy production? And what factors can be adjusted to optimize production throughout the day, the week and season-by-season? These are just some of the questions that a team of data scientists have asked and answered about the SAS solar farm using data, drones
Data scientists naturally use a lot of machine learning algorithms, which work well for detecting patterns, automating simple tasks, generalizing responses and other data heavy tasks. As a subfield of computer science, machine learning evolved from the study of pattern recognition and computational learning theory in artificial intelligence. Over time, machine learning has borrowed from many
We’re proud of our unique company culture that spans across offices, divisions and geographies. It’s one of the reasons SAS was recently named among the top workplaces in the world by Fortune’s Great Place to Work! If you’re curious about what it is that makes SAS such a great place to work, one answer
This article discusses how to restrict a multivariate function to a linear subspace. This is a useful technique in many situations, including visualizing an objective function that is constrained by linear equalities. For example, the graph to the right is from a previous article about how to evaluate quadratic polynomials.
Getting value from analytics is becoming top of mind for businesses. Organizations have invested millions of dollars in data, people and technology and are looking for a return on their investment. That requires operationalizing analytics so that it can be used for strategic decision making -- often referred to as
Ladies and gentlemen, I give you Value-Based Payments (VBP), health care’s new magic, “silver bullet” that will solve all our fraud problems. Last month, the US Department of Health and Human Services (HHS) issued a press release entitled, “HHS Proposes Stark Law and Anti-Kickback Statute Reforms to Support Value-Based and
US military veterans are mission-focused, team-oriented and natural leaders that benefit any organization that hires them. Many of today's veterans organizations use data and analytics to help transition military members and their spouses find rewarding civilian careers. SAS supports those efforts and we're also proud to offer many programs to

Every year at Halloween, I post an article that shows a SAS trick that is a real treat. This article shows how to use the INTNX function to find dates that are related to a specified date. The INTNX function is a sweet treat, indeed. I previously wrote an article
Validating and testing our supervised machine learning models is essential to ensuring that they generalize well. SAS Viya makes it easy to train, validate, and test our machine learning models.
I recently wrote about how to use PROC TTEST in SAS/STAT software to compute the geometric mean and related statistics. This prompted a SAS programmer to ask a related question. Suppose you have dozens (or hundreds) of variables and you want to compute the geometric mean of each. What is
We've had record high 90+ degree temperatures here in the southeast US this past week (September / October), and it has made me appreciate having an air conditioner. Indeed, air conditioners were pretty much invented here in North Carolina (see Eric Cramer). They are used in pretty much every building
Time-series decomposition is an important technique for time series analysis, especially for seasonal adjustment and trend strength measurement. Decomposition deconstructs a time series into several components, with each representing a certain pattern or characteristic. This post shows you how to use SAS® Visual Analytics to visually show the decomposition of
When you order an item online, the website often recommends other items based on your purchase. In fact, these kinds of "recommendation engines" contributed to the early success of companies like Amazon and Netflix. SAS uses a recommender engine to suggest articles on the SAS Support Communities. Although recommender engines
