Strengthen your programming skills with tips and techniques from the experts
Kevin Russell of SAS Technical Support shows you how partitioning CAS tables speeds processing.
Sometimes in matrix computations, it is important to display the nonzero elements of a matrix. This can be useful for visualizing the structure of a sparse matrix (one that has many zeros) and it is also useful when describing a matrix algorithm (such as Gaussian elimination) that introduces zeros at
In the second post of the Getting Started with Python Integration to SAS® Viya® series we will learn about Working with CAS Actions and CASResults Objects. CAS actions are commands sent to the CAS server to run a task, and CASResults objects contain information returned from the CAS server. This
CAS Actions and Action Sets - a brief intro - A quick introduction about the distributed CAS server in SAS® Viya®. Index of articles on Getting Started with Python Integration to SAS Viya. Making a Connection - An introduction to SAS Viya and the massively parallel processing CAS engine, and
SAS Public Sector's Elena Shtern is your guide as you extract data from the Federal Reserve Economic Data site using the SASEFRED interface engine, part of SAS/ETS® software.
A previous article shows how to use the iml action to read a CAS data table into an IML matrix. This article shows how to write a CAS table from data in an IML matrix. You can read an overview of the iml action, which was introduced in SAS Viya
A previous article compares a SAS/IML program that runs in PROC IML to the same program that runs in the iml action. (You can read an overview of the iml action.) The example in the previous article was very simple and did not read or write data. This article compares
A previous article provides an introduction and overview of the iml action, which is available in SAS Viya 3.5. The article compares the iml action to PROC IML and states that most PROC IML programs can be modified to run in the iml action. This article takes a closer look
Whether you enjoy debugging or hate it, for programmers, debugging is a fact of life. It’s easy to misspell a keyword, scramble your array subscripts, or (heaven forbid!) forget a semicolon. That’s why we include a chapter on debugging in The Little SAS® Book and its companion book, Exercises and
This article introduces the iml action, which is available in SAS Viya 3.5. The iml action supports most of the same syntax and functionality as the SAS/IML matrix language, which is implemented in PROC IML. With minimal changes, most programs that run in PROC IML also run in the iml
Learning never stops. When SAS had to change this year’s SAS Global Forum (SASGF) to a virtual event, everyone was disappointed. I am, however, super excited about all of the papers and stream of video releases over the last month (and I encourage you to register for the upcoming live
In natural language processing, word vectors play a key role in making technologies such as machine translation and speech recognition possible. Let's talk about how to transform word vector tables from long to wide in SAS, so we can potentially get sentence vectors to process further.
While working at the Rutgers Robert Wood Johnson Medical School, I had access to data on over ten million visits to emergency departments in central New Jersey, including ICD-9 (International Classification of Disease – 9th edition) codes along with some patient demographic data. I also had the ozone level from
SAS' Leonid Batkhan describes programming technique for creating multi-purpose SAS® Macro functions.
This article shows how to perform two-dimensional bilinear interpolation in SAS by using a SAS/IML function. It is assumed that you have observed the values of a response variable on a regular grid of locations. A previous article showed how to interpolate inside one rectangular cell. When you have a
One of the problems that trips up experienced SAS users when they begin to use SAS Enterprise Guide is a result of simple geography. The SAS Enterprise Guide application runs here, on your desktop. The SAS Workspace session (which accesses data and cranks through your analysis) runs over there, on
If you're close to my age, you probably remember Joe Walsh's song Ordinary Average Guy. That song popped into my head when I was writing this example about moving averages, so I encourage you to listen to it while reading the blog post. Many people are looking at graphs lately
I've previously written about linear interpolation in one dimension. Bilinear interpolation is a method for two-dimensional interpolation on a rectangle. If the value of a function is known at the four corners of a rectangle, an interpolation scheme gives you a way to estimate the function at any point in
This blog demonstrates how to modify your ODS HTML code to make your column headers “sticky,” or fixed in position. Using sticky headers is most beneficial when you have long tables on your web page and you want the column headers to stay in view while scrolling through the rest of the page.
You’ve chosen the right class, added-to-cart, and hit submit. You’re committed – now what? Once you book a class with us, no matter the format, you can expect an email confirming your request within 24 hours. For instructor-led training courses, a reminder email is sent 3-5 days before the course
I recently showed how to use linear interpolation in SAS. Linear interpolation is a common way to interpolate between a set of planar points, but the interpolating function (the interpolant) is not smooth. If you want a smoother interpolant, you can use cubic spline interpolation. This article describes how to
As we continue to process and understand the ongoing effects of the novel coronavirus, many of us have grown used to viewing COVID-19 dashboards and visualizations, including this popular coronavirus dashboard from SAS. If you are more accustomed to building graphs and visualizations using the SGPLOT and SGPANEL procedures, this
In this edition of Problem Solvers, SAS Technical Support's Kathryn McLawhorn walks you through two PROC REPORT techniques.
SAS programmers sometimes ask about ways to perform one-dimensional linear interpolation in SAS. This article shows three ways to perform linear interpolation in SAS: PROC IML (in SAS/IML software), PROC EXPAND (in SAS/ETS software), and PROC TRANSREG (in SAS/STAT software). Of these, PROC IML Is the simplest to use and
With increasing interest in Continuous Integration/Continuous Delivery (CI/CD), many SAS Users want to know what can be done for Visual Analytics reports. In this article, I will explain how to use Python and SAS Viya REST APIs to extract a report from a SAS Viya environment and import it into another environment.
I've previously written about how to generate points that are uniformly distributed in the unit disk. A seemingly unrelated topic is the distribution of eigenvalues (in the complex plane) of various kinds of random matrices. However, I recently learned that these topics are somewhat related! A mathematical result called the
Modelos de machine learning estão cada dia mais em alta no mercado de trabalho. Mas o que são esses modelos? Por que eles ganharam tanto destaque? Por que todos querem usar? Gosto de dizer que modelos de machine learning são modelos estatísticos acrescidos de poder computacional, e que as empresas
SAS' Leonid Batkhan differentiates between SAS macro and programming languages, defines two types of SAS macros and much more.
Updated Nov. 18, 2020 The demand for data skills has been growing at a rapid rate and will continue to progress for years to come. According to the World Economic Forum (WEF), Data and AI will experience the highest annual growth rate for job opportunities, at 41%. It’s no surprise
Welcome to the first post for the Getting Started with Python Integration to SAS Viya series! With the popularity of the Python programming language for data analysis and SAS Viya's ability to integrate with Python, I thought, why not create tutorials for users integrating the two? To begin the series
