Sir Tim Berners-Lee is famous for inventing the World Wide Web and for the construction of URLs -- a piece of syntax that every 8-year-old is now familiar with. According to the lore, when Sir Tim invented URLs he did not imagine that Internet surfers of all ages and backgrounds
Being the Graph Guy, I wanted to know about all the "data visualization" presentations at the upcoming SAS Global Forum 2018 conference. I tried going through the official interface to search for such sessions, but it was difficult (impossible?) to know that I had found them all. Therefore I created
When speed is required at scale, it's hard to beat parallel processing data in memory with DS2 and SAS® Viya® with the amazing Cloud Analytic Services (CAS)!
Correlation is a statistic that measures how closely two variables are related to each other. The most popular definition of correlation is the Pearson product-moment correlation, which is a measurement of the linear relationship between two variables. Many textbooks stress the linear nature of the Pearson correlation and emphasize that
I love to walk. It takes just a couple of minutes and I am completely immersed in all the beauty that nature has to offer. Here in North Carolina we’re currently enjoying the flowering magnolia and cherry trees, the last of the daffodils, tulips that began to open just a
I have 3 mantras: less is more; you must start the way you want to finish; and, life is short but wide. As many of you know, I’m a planner. I’ve had my funeral folder since I was 19. Even with my good genes (my 98 year old father is
In the extended enterprise, data integration challenges abound. David Loshin explains.
If you grew up as a space-junkie kid like me, then you've probably been watching the news for the past few days, wondering when and where China's Tiangong 1 space station was going to fall out of orbit, and crash to Earth. According to Popular Mechanics (PM), that happened at 8:16pm
As a general rule, when SAS programmers want to manipulate data row by row, they reach for the SAS DATA step. When the computation requires column statistics, the SQL procedure is also useful. When both row and column operations are required, the SAS/IML language is a powerful addition to a
Inspired by curiosity and backed by the most powerful analytics in the world, SAS discovers a new planet in our Solar system. See how we used SAS Viya to make this historic discovery.
Gradient boosting is one of the most widely used machine learning models in practice. See how to use gradient boosting model for classification in SAS Visual Data Mining and Machine Learning.
Learn about the new feature of SAS Viya 3.3 that enables Kerberos delegation throughout the environment. It allows you to have end-user sessions in SAS Cloud Analytics Services that are able to use Kerberos to connect to Secured Hadoop.
With SAS Viya 3.3, a new data transfer mechanism Multi Node Data Transfer has been introduced to transfer data between the data source and the SAS’ Cloud Analytics Services. Learn more about this feature.
SAS product manager, author and community contributor Gerhard Svolba shares 10 reasons to look forward to SAS Global Forum 2018.
With the release of SAS Viya 3.3, you now have the ability to pass implicit SQL queries to a variety of SQL data sources, including Hive. Here's what happens as users write SAS compliant SQL code.
These days, it's all about music streaming ... You sign up for a service, you let them know your music preferences, and they create a virtual "radio station" that plays the songs you probably want to hear. But that just doesn't compare with going to a physical record store, buying
The egg aisle is a confusing place! The egg cartons are plastered with pictures of happy chickens and seemingly healthy terms like farm fresh, natural, organic, free range, and cage free. So many options can make your head spin! How do you decide which one to buy? Let’s dig a
Suppose you want to find observations in multivariate data that are closest to a numerical target value. For example, for the students in the Sashelp.Class data set, you might want to find the students whose (Age, Height, Weight) values are closest to the triplet (13, 62, 100). The way to
Kim Kaluba gives examples of the benefits of data governance for data lakes.
Working in hospice I learned there was nothing I could say to erase a person’s pain, sadness, anger etc. I didn’t have that power and it would be irresponsible to think that I did. However, through education, I found that I could often ease the unnecessary additional suffering caused by misinformation and
At SAS we use data to accomplish many of our everyday tasks. At SAS Books, we have now even used data to create a data-driven book, An Introduction to SAS Visual Analytics.
As the Research Triangle Park becomes more popular, we're getting a lot more traffic on the roads. And with flexible work hours, of course I try to pick a time to drive to work when there's less traffic. I recently saw a cool infographic showing the most popular times when
You have the infrastructure, and you know that DATA step would run so much better in DS2, but it’s complicated and you don’t know how to get started. Well, if you have SAS 9.4M5, rejoice! The DStoDS2 procedure is here, and it’s a humdinger! (No, Chris, not a Hemedinger… ;-) It's
Simulation studies are used for many purposes, one of which is to examine how distributional assumptions affect the coverage probability of a confidence interval. This article describes the "zipper plot," which enables you to compare the coverage probability of a confidence interval when the data do or do not follow
We all have different learning styles. Some learn best by seeing and doing; others by listening to lectures in a traditional classroom; still others simply by diving in and asking questions along the way. Traditional face-to-face classroom instruction, real-time classes over the Internet, or self-paced instruction with exercises, SAS Education
Generating HTML output might be something that you do daily. After all, HTML is now the default format for Display Manager SAS output, and it is one of the available formats for SAS® Enterprise Guide®. In addition, SAS® Studio generates HTML 5.0 output as a default. The many faces of
I often claim that the "natural syntax" of the SAS/IML language makes it easy to implement an algorithm or statistical formula as it appears in a textbook or journal. The other day I had an opportunity to test the truth of that statement. A SAS programmer wanted to implement the
Jim Harris says streaming data analytics can drive better decisions and faster adaptation to changing conditions.
As I write this we are halfway through teaching our first Powerful Tools for Caregiving class. It has been an exciting time of learning and growth for all of us. Each time I work with caregivers, I am reminded of a common theme – the delicate dance of trying to
About once a month I see a question on the SAS Support Communities that involves what I like to call "computations with combinations." A typical question asks how to find k values (from a set of p values) that maximize or minimize some function, such as "I have 5 variables,
