The most fundamental concept that students learning introductory SAS programming must master is how SAS handles data. This might seem like an obvious statement, but it is often overlooked by students in their rush to produce code that works. I often tell my class to step back for a moment
Katherine Taylor explains how and why new data improves risk models.
A common operation in statistical data analysis is to center and scale a numerical variable. This operation is conceptually easy: you subtract the mean of the variable and divide by the variable's standard deviation. Recently, I wanted to perform a slight variation of the usual standardization: Perform a different standardization
Identification of Concepts and Topics based on out-of-the-box rules. It is common practice to develop a business or industry specific taxonomy.
An embedding model is a way to reduce the dimensionality of input data, such as images. Consider this to be a type of data preparation applied to image analysis. When an embedding model is used, input images are converted into low-dimensional vectors that can be more easily used by other computer vision tasks. The key to good embedding is to train the model so that similar images are converted to similar vectors.
In the early days of the COVID-19 pandemic, the issue of tax administration was low on the agenda for most. Beyond the obvious public health concerns, most business and government leaders were focused on how best to keep businesses afloat. But for those in federal, state and local governments responsible
Data collected during the manufacturing process is used to try to identify the cause of discrete problems after the event.
Have you ever seen the "brain teaser" for children that shows a 4 x 4 grid and asks "how many squares of any size are in this grid?" To solve this problem, the reader must recognize that there are sixteen 1 x 1 squares, nine 2 x 2 squares, four 3 x 3 squares, and one 4 x 4 square.
In this guest blogpost, Work/Life welcomes Jamie Pack, College Planning Consultant with Advantage College Planning, to help parents and students sort through the issue of declaring a major…or not…during the college application process. Is there any value in applying to college without a declared major? Yes! In a time where
The iml action was introduced in Viya 3.5. As shown in a previous article, the iml action supports ways to implement the map-reduce paradigm, which is a way to distribute a computation by using multiple threads. The map-reduce paradigm is ideal for “embarrassingly parallel” computations, which are composed of many
I spoke with Antonie Berkel and Dr. Joost Huiskens about a systems analysis project for the design of a clinical decision support system (CDSS) which integrates computer vision to help radiologists monitor the progression of tumors.
Let's learn how to prompt for a date range in a SAS Visual Analytics report using control objects such as sliders, drop-down lists, and text input.
You want to use an API to retrieve data and process it with SAS. How do you do it? PROC HTTP offers the features of the cURL command within your SAS code.
How can organizations be more resilient during an uncertain business and public health situation? Lessons learned from organizations at the front lines of crisis response reinforce the importance of good analytic governance. These leading organizations have shown us that the fundamentals of the analytic life cycle – data, discovery and
It’s National Intern Day! Created by WayUp, National Intern Day is a holiday dedicated to recognizing and celebrating the future leaders of the world: Interns. At SAS, we feel like every day should be Intern Day, but #NationalnternDay presents a unique opportunity to celebrate the value interns bring to our company. This
SAS instructor Raymond Thomas touts the benefits of Report Center, part of SAS Environment Manager Extended Monitoring.
When you write a program that simulates data from a statistical model, you should always check that the simulation code is correct. One way to do this is to generate a large simulated sample, estimate the parameters in the simulated data, and make sure that the estimates are close to
Each of us has been impacted by the COVID-19 pandemic in a myriad of ways. In March we dove deep, headfirst, into a number of emotions and a new way of life that is ever-evolving. Some people may find they are drinking more in one night or more days of
For many retailers, the biggest challenge was simply to have enough staff to get products onto shelves quickly enough.
SAS instructor Raymond Thomas describes a typical day in the life of a SAS Administrator.
Dashboards and metrics support data-driven decisions – if you understand the terms.
The Kronecker product (also called the direct product) is a binary operation that combines two matrices to form a new matrix. The Kronecker product appears in textbooks about the design of experiments and multivariate statistics. The Kronecker product seems intimidating at first, but often one of the matrices in the
Alena caught up with Pedro Peleja, Technology Transformation Director at Una Seguros, to talk about digital transformation.
Turn analytical models into business value and smarter decisions with this special collection of papers about SAS Model Management. Without a structured and standardized process to integrate and coordinate all the different pieces of the model life cycle, a business can experience increased costs and missed opportunities. SAS Model Management solutions enable organizations to register, test, deploy, monitor, and retrain analytical models, leveraging any available technology – including open-source models in Python, R, and TensorFlow –into a competitive advantage.
SAS' Leonid Batkhan shows you how to split a large data set into many by a subsetting by a number of observations to produce smaller, better manageable data sets.
Move from rapid response to long-term resiliency based on these 5 tips.
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
COVID-19 has significantly altered our lives in many ways. While we continue to focus on mitigating infection rates by staying at home, social distancing when out, frequent handwashing and wearing masks, it’s important to think about how we can increase our resilience so that if we do get sick with
For SAS and its partners, it provides opportunities for growth, new markets, and better service.
