It can be frustrating when the same probability distribution has two different parameterizations, but such is the life of a statistical programmer. I previously wrote an article about the gamma distribution, which has two common parameterizations: one that uses a scale parameter (β) and another that uses a rate parameter
SAS' Rajesh Selukar introduces you to a new scoring feature.
“En la era digital, la economía de los datos se está convirtiendo en el nuevo ´oro negro´ que aceita el motor del crecimiento económico. Los datos, masivos y abiertos, son esenciales para mejorar la confianza de los ciudadanos en sus estados y hacerles partícipes de la acción pública, facilitando el
Eu sou Professor de Data Science já há alguns anos, e não é incomum, entre alunos e colegas termos ricas conversas e debates sobre o tema Inteligência Artificial e Machine Learning. Me lembro de uma aula onde os alunos colocaram questões tão interessantes que as respostas direcionaram aquela aula e
This blog post is mostly just a bunch of fun maps ... maps that are labeled (or mislabeled) in various ways, using fun/interesting data. I focus on the 'fun' part, but if you're not careful you might also learn a little about the various ways to add labels to maps
Rijkswaterstaat (RWS) is the Netherlands main agency for design, construction, management and maintenance for waterways and infrastructure. Their mission is to promote safety, mobility and quality of life in the Netherlands. They are the masterminds behind some of the most prestigious water projects in the world. In a recent panel
Following is editor Len Tashman's preview of the 2021-Q4 issue of Foresight: The International Journal of Applied Forecasting. Preview of Foresight #63 (2021-Q4) FORESIGHT HALL OF FAME Adopting the idea from other journals that recognize outstanding contributions to the field through best paper awards, we are pleased to announce that
These days, many countries are moving away from coal, and towards natural gas, hydro, wind, and solar as ways to meet their electricity needs. I had heard that some countries still use a lot of coal (especially those countries with large coal deposits), and I was curious which countries use
I'm not sure when it started, but I've had this lifelong situation that began small, I'm sure, and then grew! While I've encouraged it to become a friend, some days it is not. You may ask who or what this friend is. It's a little thing called perfectionism. It can
A genetic algorithm (GA) is a heuristic optimization technique. The method tries to mimic natural selection and evolution by starting with a population of random candidates. Candidates are evaluated for "fitness" by plugging them into the objective function. The characteristics of the better candidates are combined to create a new
In this Q&A with MIT/SMR Connections, Iain Brown, SAS’s head of data science for the United Kingdom and Ireland, discusses some key risks, ethical issues, and platform questions that organizations should consider before adopting AI and takes a quick look at current and emerging AI trends. Q: In your view,
Every year, the SAS Championship brings a week of sports, leadership and literacy activities to the Raleigh area. Take a minute to enjoy this photo album from the week, and visit the SAS Championship online or on Twitter to learn more about the tournament, the winners and the fundraisers.
If you’ve switched on the news recently, you’ll have noticed how the words “supply chain” have now become part of Britain’s everyday vocabulary. From fuel shortages at petrol stations to the terrifying prospect of a Christmas turkey shortage, we’ve suddenly become aware of how precarious our society is, and how
SAS' Bahar Biller, an operations researcher, details how to develop a supply chain digital twin.
This article uses an example to introduce to genetic algorithms (GAs) for optimization. It discusses two operators (mutation and crossover) that are important in implementing a genetic algorithm. It discusses choices that you must make when you implement these operations. Some programmers love using genetic algorithms. Genetic algorithms are heuristic
Recently, the news has been all abuzz about William Shatner traveling into space. This was a cool event because he's the oldest person who has traveled into space (at 90 years old) ... and he was also the iconic Captain Kirk from the original Star Trek television series. This got
전 세계적으로 기후변화 대응과 지속가능발전을 위한 금융기관의 역할이 강조되고 있습니다. 이를 위한 금융기관의 노력을 지원하기 위해 SAS는 딜로이트와 함께 지난 10월, 금융권 기후 리스크 관리를 위한 ESG 세미나를 개최했습니다. 그 중 일부를 소개합니다. 금융기관이 기후 리스크를 관리해야 하는 이유 기후 리스크는 크게 물리적 리스크와 전이 리스크로 구분됩니다. 물리적 리스크는 농업에
More than four decades ago, SAS developed a breakthrough system that helped farmers and researchers better understand and analyze crop yields and livestock production. It was pioneering work that laid a foundation for the emerging field of advanced analytics. While SAS has continued to grow and serve many other industries,
Have you ever thought of a sweet potato as ugly? These tuberous, root vegetables are a holiday staple, but the sweet potato industry prefers a certain size, shape and weight for them to make it to your grocery store. Many farmers even leave the potatoes deemed “ugly” in the fields,
Generative adversarial networks (GANs) are one of the newer machine learning algorithms that data scientists are tapping into. When I first heard it, I wondered how can networks be adversarial? I envisioned networks with swords drawn going at it. Close… but I can assure you that no networks were harmed in the making of this article.
Sometimes we can learn as much from our mistakes as we do from our successes. Recently, I needed to solve an optimization problem for which the solution vector was a binary vector subject to a constraint. I was in a hurry. Without thinking much about what I was doing, I
Caroline Payne, Head of Customer Advisory, SAS UK Public Sector Team Digital innovation across governments around the world has accelerated in the last 18 months as leaders turn to data and technology to deliver rapid responses to the pandemic. Public organisations have had to move quickly, whilst being acutely aware
The rumors are true - The Graph Guy is retiring! I've been working at SAS for about 30 years, and had lots of fun stretching the limits of SAS' graphing & mapping software over the years. But I've decided to retire while I'm still young enough to pursue a lot
“No one wants to be sold to, not even the most eager buyer in the world,” says Farnoosh Brock, a corporate trainer, speaker and writer. Brock is also an engineer and author of the book, The Serving Mindset: Stop Selling and Grow Your Business. She is a proponent of selling

Construction is the second largest industry in the world with a market value of $12.5 trillion, accounting for 13% of the world’s GDP. Financial services are the only industry ahead of construction, with a market value of $22.5 trillion. There are many differences between the two industries, but the most
SAS' Udo Sglavo and Jan Chvosta discuss the power of a regression framework and choosing the correct regression model.
Many optimization problems in statistics and machine learning involve continuous parameters. For example, maximum likelihood estimation involves optimizing a log-likelihood function over a continuous domain, possibly with constraints. Recently, however, I had to solve an optimization problem for which the solution vector was a 0/1 binary variable. To solve the
Overlapping social issues and additional uncertainties – not to mention a global pandemic - have led to a massive spike in people seeking mental health support. Much of that extra demand has been absorbed virtually. Canada’s Centre for Addiction and Mental Health, for example, has seen its monthly demand for
SCUBA diving is one of those activities that should be on your bucket list - everyone should experience it at least once! But where should you go diving? ... Coral reefs are always popular - and they are typically in shallow water, making it an 'easy' dive. But, being in
