Last month a SAS programmer asked how to fit a multivariate Gaussian mixture model in SAS. For univariate data, you can use the FMM Procedure, which fits a large variety of finite mixture models. If your company is using SAS Viya, you can use the MBC or GMM procedures, which
Everyone is familiar with The Confidence Man. This person can spout any sort of nonsense and easily demonstrable lies, and yet 40% of the people still believe him. The Confidence Man exposes a curious characteristic about human behavior: If you make your assertions with extreme confidence, no matter how obviously
For SAS and its partners, it provides opportunities for growth, new markets, and better service.
Una vez más, una crisis demuestra que la realidad tiene su lado crudo, pero también que es una oportunidad para evolucionar. En el entorno empresarial, la actual pandemia ha planteado enormes retos económicos para las organizaciones: ha puesto en riesgo la rentabilidad y continuidad de algunas, mientras que impulsó las
What leads to development of Machine Learning and Artificial Intelligence techniques to find complex patterns in data?
July marks the 30th anniversary of the Americans with Disabilities Act (ADA), a landmark civil rights legislation that has positively impacted the lives of millions of people with disabilities in the United States. It’s always a good time to hear the perspectives of others, and this time presents a unique
When Liverpool clinched the Premier League title with a win on June 25, my household was giddy. We are a family of sports fans, and we especially love baseball (Go, Red Sox!) and soccer. I’m a relative newbie to Liverpool, having cheered for them for the last five years. Having
If the UK economy is going to achieve the target of bringing all greenhouse gas emissions to net zero by 2050 the application of Intelligent Decisioning will play a major role in helping achieve this target.
I recently showed how to compute within-group multivariate statistics by using the SAS/IML language. However, a principal of good software design is to encapsulate functionality and write self-contained functions that compute and return the results. What is the best way to return multiple statistics from a SAS/IML module? A convenient
L'Intelligence Artificielle (IA) et l'analytique aident à la détection des premiers symptômes indicateurs d'une possible épidémie. Ce qui contribue largement à limiter la propagation d'un virus. Il faut pouvoir compter sur des techniques analytiques capables de repérer des événements rares mais significatifs, comme une hausse de l'absentéisme dans une école
Ever heard of a Turducken? It's a chicken stuffed inside a duck that's stuffed inside a turkey along with layers of stuffing (which I just learned is referred to as a three-bird roast outside the US and Canada; there's also an English variant known as a gooducken, where the turkey
Utility companies have a choice: aggressive debt collection, or debt forgiveness or ‘holidays’.
IIASA(International Institute for Applied Systems Analysis, 국제응용시스템분석연구소)는 인류가 당면한 전 세계 환경과 경제, 기술, 사회적 변화로 인한 문제를 연구하는 독립적인 국제 과학 연구소입니다. 이곳에서는 특히, 글로벌 환경과 사회에 영향을 미치는 요소와 그 원인을 명확히 이해하기 위해 분석 기술을 적극 활용하고 있습니다. SAS는 교육, 환경, 건강, 인권, 빈곤 등 다양한 사회
As companhias de seguros enfrentam diferentes exigências por parte dos clientes e num cenário cada vez mais fraturante e competitivo. Na verdade, elas precisam de ser capazes de usar os dados e o conhecimento, de forma rápida e eficaz, para se manterem na linha da frente. Durante a crise do

Why fraud prevention and anti-money laundering teams can learn a lot from each other—and how convergence can benefit both.
I was supposed to be behind a desk downing M&M’s and enjoying the SAS campus and all its glory. But instead, I’m working from home as an external communications intern. Working from home has been a blessing filled with challenges I never thought I’d experience this summer. The first one
The multivariate normal distribution is used frequently in multivariate statistics and machine learning. In many applications, you need to evaluate the log-likelihood function in order to compare how well different models fit the data. The log-likelihood for a vector x is the natural logarithm of the multivariate normal (MVN) density
SAS experts point to five trends that are shaping the future for digital tax administration.
Human brains are hardwired to build maps. We navigate the world around us through the creation of mental maps. Maps that assemble abstract landmarks and build spatial relationships between them. If you think about how you navigate through your house, even in the dark, it is quite amazing. Maps have
A previous article introduces the MAPREDUCE function in the iml action. (The iml action was introduced in Viya 3.5.) The MAPREDUCE function implements the map-reduce paradigm, which is a two-step process for distributing a computation to multiple threads. The example in the previous article adds a set of numbers by
회복이란 무엇일까요? 정상 상태로 돌아가는 것, 잃어버린 것을 되찾는 것, 통제와 안전을 되찾는 것... 평상시로 돌아가는 것은 지금은 힘든 일처럼 느껴지지만 조직의 회복 정도는 지금과 같은 혼란기에 리더가 취하는 조치에 달려 있습니다. 이번 SGF 시리즈에서는 팬데믹 시기의 혼란기를 리더는 어떻게 대응해야 하는지 살펴보고자 이코노미스트와 함께 조사한 ‘글로벌 비즈니스 바로미터(이하, GBB)’
During the 2020 Coronavirus pandemic, you've probably formed a great appreciation for good, informative graphics. Good graphics can help you get a handle on thousands of individual data values, see the geographical distribution, or look for trends. In February, I wrote a blog post about creating a coronavirus dashboard with
Last month, SAS and Microsoft announced a new strategic partnership – one that we believe will shape the future of analytics and artificial intelligence. You may be wondering as a customer what this partnership means for you. As an IT leader, I’ve had a front-row seat for the collaborative relationship
How have healthcare providers and governmental agencies predicted the fast-changing, potentially exponential increase in the need for medical services and equipment through the various stages of the COVID-19 pandemic? Mathematical techniques that attempt to model and understand the likely spread of the disease have been instrumental. The SEIR model is
The current state of policy enforcement during an infectious disease pandemic is mostly reactive. Public health officials track changes in active cases, identify hot-spots and enforce containment policies primarily based on geographic proximity. By combining telecommunications data -- which we turn into mobility information -- with public health data of
The iml action in SAS Viya (introduced in Viya 3.5) provides a set of general programming tools that you can use to implement a custom parallel algorithm. This makes the iml action different than other Viya actions, which use distributed computations to solve specific problems in statistics, machine learning, and
질병 확산을 억제하고 경제적 영향을 최소화하기 위해서는 인구가 어떻게 이동하는지 분석하고, 지역 내 접촉자를 추적하여 적절한 의사결정을 해야 합니다. 이번 SGF 시리즈에서는 인구 이동 분석과 접촉자 추적 등 SAS 분석 기술이 어떻게 팬데믹 극복을 위한 의사결정을 지원하는지에 대한 SAS 짐굿나잇 회장과 스티브 베넷 글로벌 정부기관 프랙티스 부문 이사의 세션을 소개합니다.
