Many statistical tests use a CUSUM statistic as part of the test. It can be confusing when a researcher refers to "the CUSUM test" without providing details about exactly which CUSUM test is being used. This article describes a CUSUM test for the randomness of a binary sequence. You start
By using data provided by a Game of Thrones fan, we use SAS to look at screen time for scene locations and characters in this crazy popular show.
The financial services industry is under continued pressure to create more convenient ways of paying for goods and services. This trend goes beyond common hype. It’s a cultural shift from long-standing payment methods traditionally defined by industry heavyweights to embracing market demands and delivering customer-centricity. With digitisation, new market entrants
At SAS, we have a multidimensional culture that blends our different backgrounds, experiences, and perspectives from employees all over the world. As the Diversity and Inclusion Manager, I’ve had open conversations with employees regarding the value that neurodiversity brings to the creative process and to our organization. But I’m not the
Did you recently lock in a mortgage rate of 3.5-5%, or perhaps even lower? How do today's rates compare to rates in the past? Let's dig a little deeper into this topic, with some graphs! But before we get started, here's a picture to get you into the mood for
The journey of life rarely follows the expected path. Last year around this time I experienced the most devastating loss I will likely ever experience in my life; the loss of our only daughter, Mamie. The grieving process is new to me, as is the earth-shattering devastation of unfulfilled hopes,
I think every course in exploratory data analysis should begin by studying Anscombe's quartet. Anscombe's quartet is a set of four data sets (N=11) that have nearly identical descriptive statistics but different graphical properties. They are a great reminder of why you should graph your data. You can read about
This blog post is based on the Code Snippets tutorial video in the free SAS® Viya® Enablement course from SAS Education. Keep reading to learn more about code snippets or check out the video to follow along with the tutorial in real-time. Has there ever been a block of code
If a bank gets in touch with a software company and wants to know how it could use artificial intelligence (AI), that means two things. First, the bank is willing to consider AI, and second, that it really does not know much about the subject. Banks want AI, and they
Anti-money laundering has been an issue for banks and financial institutions for some time. Transaction monitoring systems have been around for many years. Meeting and complying with regulations at the regional or national level, however, remains a challenge. Many financial institutions are almost playing catch-up with regulators, as anti-money laundering
In the past, I created some graphs about our record low unemployment rate (US unemployment, and state-level unemployment), but does low unemployment also mean there are jobs available? Let's have a look at the data!... Existing Graphs I knew I couldn't be the only one interested in this kind of
A quadratic form is a second-degree polynomial that does not have any linear or constant terms. For multivariate polynomials, you can quickly evaluate a quadratic form by using the matrix expression x` A x This computation is straightforward in a matrix language such as SAS/IML. However, some computations in statistics
More and more organizations are moving to the cloud, but for some moving data isn’t an option. With a remote managed software and services (RMSS) solution deployment, however, it’s still possible to experience the benefits of cloud, without the data or solution ever leaving your premises or existing cloud provider.
Which topics and priorities will be the focus for chief risk officers in 2019? A range of experts and representatives of major banking institutions addressed these questions at a recent event, CRO and CFO Banking Agenda 2019, organised by CeTIF, the Research Center on Technologies, Innovation and Financial Services, in collaboration
At the end of my SAS Users blog post explaining how to install SAS Viya on the Azure Cloud for a SAS Hackathon in the Nordics, I promised to provide some technical background. I ended up with only one manual step by launching a shell script from a Linux machine
Anti-money laundering is an important issue for governments and banks alike. The fight to prevent terrorist financing and profiting from crime means that banks and other financial institutions are increasingly required by regulations to put anti-money laundering systems in place. Many are turning to analytics in the process, and particularly to
At the risk of oversimplifying, I think of artificial intelligence as what becomes possible after you’ve fully embraced analytics and you’re starting to get bolder about how to use it. Your models are getting better, your predictions are more accurate, your results are stronger and over all, confidence grows in
The past few years, I've created maps showing things you might visit and do during the big SAS Global Forum (SASGF) conference. This year the conference is in Dallas, and ... you guessed it ... I've created a Dallas map! If you're familiar with my previous maps, you know that
What's the impact of using data governance and analytics for the business side of education? It's an interesting question, and during a video interview, Dale Pietrzak, Ed.D.,Former Director of Institutional Effectiveness and Accreditation (IEA) at the University of Idaho shared details on the results they're realizing from using SAS for
This blog post could be subtitled "To Catch a Thief" or maybe "Go ahead. Steal this blog. I dare you."* That's because I've used this technique several times to catch and report other web sites who lift the blog content from blogs.sas.com and present it as their own. Syndicating blog
The number of models used by large operators in the financial sector is increasing by around 10 to 25 percent per year. Most of the new models are designed to meet business needs, such as pricing, the definition of strategic plans and the management of liquidity. Some, though, are for
Jim Harris shares examples of how and why AI applications are dependent on high-quality data.
Salads are the image most of us see in our heads when we think of healthy eating. And for good reason, they can be really healthy. However, it is possible (and very common) for salads to end up being not so healthy, or just not enough for a meal.
Hackathons are short-term programming events that use data and analytics to solve real-world challenges. They have been around for a while now, and there is general agreement that they are great opportunities for networking and experimenting. There is also, however, now a growing sense that organisations can use them to
In numerical linear algebra, there are often multiple ways to solve a problem, and each way is useful in various contexts. In fact, one of the challenges in matrix computations is choosing from among different algorithms, which often vary in their use of memory, data access, and speed. This article
Natural language understanding (NLU) is a subfield of natural language processing (NLP) that enables machine reading comprehension. While both understand human language, NLU goes beyond the structural understanding of language to interpret intent, resolve context and word ambiguity, and even generate human language on its own. NLU is designed for
The recently released results of a new joint survey from SAS and the Global Association of Risk Professionals (GARP) on the use of AI in risk management makes for very interesting reading. Here are the highlights from the study, which involved more than 2,000 participants from across the global financial
Chances are that sometime in your life you have been hurt by gossip. We probably all agree that gossip is wrong. It spreads negativity in our workplaces and social groups. It is designed to make someone else look bad and to isolate them from the group. It encourages people to
Let’s be blunt. Procurement fraud is a problem. Orders and purchase procedures are one of the most vulnerable areas of corruption. The scale of irregularities and abuse in the procurement area is large. In fact, procurement fraud is the second-biggest economic crime after theft. Estimates suggest that businesses can
Have you ever wondered if love at first sight really exists? And if it exists, what qualities are people drawn too? Watch any romantic comedy and you’ll see this phenomenon play out on the big screen. Which begs the question, “If it can happen to them why not me?” Let’s
