News outlets share stats and graphs that they source from public data. It takes data literacy skills to critique the stats you see, and investigate more.
How we built a recommendation engine for new topics on communities.sas.com. We used data, machine learning, and DevOps to build a scoring engine with SAS.
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.
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
Regular expressions are a powerful method for finding specific patterns in text. The syntax of regular expressions is intimidating, but once you've solved a few pattern-recognition problems with regex, you'll never go back to your old methods.
SAS supports direct integration for Git from Base SAS (via functions), SAS Enterprise Guide, SAS Studio, and SAS Data Integration Studio. Read this article to learn how to use Git more effectively in your SAS processes.
Good news -- the SAS program that you wrote and put into production 10 years ago still works. Hey, it's SAS, so you probably take that for granted. But are those techniques from 2008 still the best way to accomplish your task? SAS 9.4, first released in 2013 and now
Have you adopted use of Microsoft Office 365? How has working "in the cloud" affected your integration with SAS applications? SAS product management wants to hear from you.
JSON is a popular format for data exchange between APIs and some modern databases. It's also used as a way to archive audit logs in many systems. Because JSON can represent hierarchical relationships of data fields, many people consider it to be superior to the CSV format -- although it's
I've collected accelerometer data with a third-party app. I've used some SAS tricks to import all of my data readings in a single step. Now I'm ready to create a report of these data in SAS Visual Analytics.
The SAS INFILE statement can read multiple text files in a single DATA step. Use file name wildcards (like * and ?) and a special FILENAME= option to keep track of which records come from which files.
How to extract driving patterns by using smartphone sensors -- especially the accelerometer. With accelerometer readings in hand, you can use spectral analysis and other techniques to decompose events, and machine learning to match differentiate from patterns of risky drivers.
How can you use analytics to design better biopsies and improve outcomes? This high school student has some ideas, and she presented them at Analytics Experience 2018.
To succeed in any data-focused hackathon, you need a robust set of tools and skills – as well as a can-do attitude. Here's what you can expect from any hackathon: Messy data. It might come from a variety of sources, and won't necessarily be organized for analytics or reporting. That's
Using relative file paths in your SAS programs? Use the new DLGCDIR function to manage your SAS working directory -- even in SAS Enterprise Guide or SAS Studio -- to ensure your programs are working the way they ought to.
"Code golf" is a fun programming pastime that challenges you to solve a problem with the least amount of code possible. Like regular golf, the goal is to use fewest code "strokes" to hit the mark. Here's a recent challenge that was posted to me via Twitter. @cjdinger @SASJedi got
SAS programmers have long wanted the ability to control the flow of their SAS programs without having to resort to complex SAS macro programming. With SAS 9.4 Maintenance 5, it's now supported! You can now use %IF-%THEN-%ELSE constructs in open code. This is big news -- even if it only
At SAS, we love data. Data is central to our corporate vision: to transform a world of data into a world of intelligence. We're also famous for enjoying M&Ms, but to us they are more than a sweet snack. They're also another source of data. My colleague Pete Privitera, with
I've said it before: spreadsheets are not databases. However, many of us use spreadsheets as if they were databases, and then we struggle when the spreadsheet layout does not support database-style rigor of predictable rows, columns, and variable types -- the basic elements we need for analytics and reporting. If
WARNING: This blog post references Avengers: Infinity War and contains story spoilers. But it also contains useful information about random number generators (RNGs) -- tempting! If you haven't yet seen the movie, you should make peace with this inner conflict before reading on. Throughout the movie, Thanos makes it clear
The title of this blog says what you really need to know: SAS Enterprise Guide does have a future, and it's a bright one. Ever since SAS Studio debuted in 2014, onlookers have speculated about its impact on the development of SAS Enterprise Guide. I think that we have been
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
Using SAS with REST APIs is fun and rewarding, but it's also complicated. When you're dealing with web services, credentials, data parsing and security, there are a lot of things that can go wrong. It's useful to have a simple program that verifies that the "basic plumbing" is working before
Is it time to add SAS to the list of "romance" languages?*. It's no secret that there are enthusiastic SAS programmers who love the SAS language. So it only makes sense that sometimes, these programmers will "nerd out" and express their adoration for fellow humans by using the code that
I've used SAS with a bunch of different REST APIs: GitHub, Brightcove, Google Analytics, Lithium, LinkedIn, and more. For most of these I have to send user/password or "secret" application tokens to the web service so that it knows who I am and what data I can retrieve. I do
If you work in a team environment, you might be accustomed to using mapped network drives for source data folders or to publish results. If you've recently moved to a SAS server environment, you might not have those mapped drives available. How can you tell? This question was posted on
The internet is rich with data, and much of that data seems to exist only on web pages, which -- for some crazy reason -- are designed for humans to read. When students/researchers want to apply data science techniques to analyze collect and analyze that data, they often turn to
Social media has brought anniversary dates to the forefront. Every day, my view of Google Photos or Facebook shows me a collection of photos from exactly some number of years ago to remind me of how good things were back then. These apps are performing the simplest of date-based math
SAS 9.4 Maintenance 5 includes new support for reading and writing GZIP files directly. GZIP files, usually found with a .gz file extension, are a different format than ZIP files. Although both are forms of compressed files, a GZIP file is usually a compressed copy of a single file, whereas
