SAS Enterprise Guide and SAS Global Forum -- two of my favorite things! And I get to talk about both of them in this post. I'm a devoted SAS Enterprise Guide user, and I hope you're learning how useful this tool can be as well. On February 13, I'll be sharing
Last week I showed three ways to sample with replacement in SAS. You can use the SAMPLE function in SAS/IML 12.1 to sample from a finite set or you can use the DATA step or PROC SURVEYSELECT to extract a random sample from a SAS data set. Sampling without replacement
Most simple graphs generally include graphical representation of data using various plot type such as bar charts, scatter plots, histograms, box plots step plots and more. Both SG procedures and GTL provide many easy ways to create such graphs. However, for many real world use cases, we need to display related textual data in
Knowing if your campaign is successful and why is not as easy as it seems. Even in ideal conditions, there are plenty of factors beyond your control, such as competitive action, sales investments, product quality, and customer-specific issues. Digital channels have added layers of complexity, while also providing the means for
Interest in "data" is at an all-time high. The popularity of search terms like "big data," "Hadoop" and the "Internet of Things" spiked dramatically in the past year. The fact is, organizations are more interested in the potential of big data platforms and data management solutions than ever before. That’s
Need to read or update a ZIP file within your SAS program? In SAS 9.4, you can use the FILENAME ZIP access method to do the job. Explanation and examples here!
Does your site have multiple people maintaining a single deployment of SAS? Is it important for them to maintain a clear audit trail of who is doing what exactly? Or do you need to update your SAS deployment using different userids? Let's take a look at some techniques to manage
Randomly choosing a subset of elements is a fundamental operation in statistics and probability. Simple random sampling with replacement is used in bootstrap methods (where the technique is called resampling), permutation tests and simulation. Last week I showed how to use the SAMPLE function in SAS/IML software to sample with
SAS users are big data consumers and big data creators. Often, we have to deal in large data files (or many smaller files) -- and that means ZIP compression. ZIP compression tools such as gzip, 7-Zip, and WinZip are ubiquitous, but they aren't always convenient to use from within a
This year the Super Bowl will take place in East Rutherford, New Jersey at MetLife Stadium just outside New York City. For the first time in this event’s 48-year history, the game will take place outdoors in a cold-weather environment, potentially subjecting players and fans to sub-freezing temperatures. The fans
As I embark on 2014, I reflect upon the many competing, yet interdependent, tensions discussed in education circles in 2013. In conferences, classrooms and statehouses, adults who care about kids debated the best ways to implement: New academic standards (Common Core State Standards or other College and Career Ready Standards)
It’s hard to believe it is almost February. The office is buzzing with all of the great things coming up in 2014 especially SAS Global Forum in just two months. But before we move too fast, I was thinking about 2013 and what really worked. The SAS Talks technical webinar
Since mead is becoming popular in movies (such as Thor and The Hobbit), and even as an emerging industry in real life ... what better example to use for some SAS graphs! And who knows - this might even turn you into a mead drinker! But first, to get you in the
Prime numbers are strange beasts. They exhibit properties of both randomness and regularity. Recently I watched an excellent nine-minute video on the Numberphile video blog that shows that if you write the natural numbers in a spiral pattern (called the Ulam spiral), then there are certain lines in the pattern
Users have often expressed the need for more marker symbols. ODS Graphics supports over 30 scalable marker symbols, both filled and empty. As mentioned in an earlier article, with SAS 9.4, filled markers can now have outlines and fills, and can also have special effects. Also with SAS 9.4, now you
This week's SAS tip is from Applied Data Mining for Forecasting Using SAS by Tim Rey, Arthur Kordon, and Chip Wells. Whether you're a forecasting practitioner, engineer, statistician, or economist, you'll appreciate the many real-world examples in the book. And hopefully this free excerpt. The following excerpt is from SAS Press
Performance management systems are becoming more important to local governments across the country. This is true for several reasons. Citizens are calling for a more accurate accounting of how their tax monies are being spent. Local government revenues have not been growing as much as in the past and, in
I remember exactly where I was when I heard that Marje Fecht was selected as the conference chair for SAS Global Forum 2014. This was April 2011, and I was at PURE Nightclub in Las Vegas. That's not my usual "clubbing" scene, but we were at the kickback party for
Even though I’ve worked as software technology marketer over the years, I have to admit that on a personal level I’ve probably related more to TV programming than software programming. When it comes to writing, I’ve always gravitated more toward crafting marketing communications than code. And when it comes to
National Reading Day promotes a love of reading and a lifetime of learning. Encouraging a strong reading foundation is at the heart of this event, which focuses on pre-K through 3rd-grade students. At SAS, we are developing tools to help parents, teachers, and students build this foundation. Our first reading app,
With each release of SAS/IML software, the language provides simple ways to carry out tasks that previously required more effort. In 2010 I blogged about a SAS/IML module that appeared in my book Statistical Programming with SAS/IML Software, which was written by using the SAS/IML 9.2. The blog post showed
Fan loyalty is everything in the sports business. So when Major League Soccer (MLS), the top flight pro soccer league in the US and Canada, wanted to deepen customer engagement, it started by getting a better understanding of its fans. MLS wanted to reach out to fans with personalized information that
In a previous post, I showed you how to send graphs with charttips & drilldowns in an email ... but what if you also need to send the graphs that you're drilling-down to? You guessed it - SAS also has a slick trick for doing that! When you create SAS graphs
If you've been following the news lately, you may have heard a lot of debate about the academic profiles of college athletes. In a recent report published by CNN, Mary Willingham, a learning specialist at UNC, argued that from 2004 to 2012 a large number of athletes were reading far
In the movie, The Matrix: Reloaded, our heroes and the KeyMaker frantically navigated from world to world through a series of doors and locks trying to escape the villains. Fortunately for our heroes, the KeyMaker always had the right key on his ring, he just had to know what key
I’m usually not one for gadgets. I tend to like practical things that I will use often. However, when I started seeing different recipes around the internet using zucchini, butternut squash or sweet potato noodles, I was intrigued!
Each year on New Year's Day I write down a list of New Year's resolutions. Most of them are garden variety resolutions – sleep more and eat better, for example – but occasionally I'll get caught up in the possibilities of a new year and commit to something I realize
I began 2014 by compiling a list of 13 popular articles from my blog in 2013. Although this "People's Choice" list contains many articles that I am proud of, it did not include all of my favorites, so I decided to compile an "Editor's Choice" list. The blog posts on
Recency, Frequency, and Monetary Analysis (or RFM) is a popular customer segmentation technique employed by database marketers everywhere. Marketers use RFM to identify which customers are most likely to respond to a direct marketing campaign. The model takes into account three simple metrics: How recently did the customer buy from
A large variety of graphs fall in the category of what I call a "Single-Cell" graph. This type of graph consists of a single data region along with titles, footnotes, legends and other ancillary objects. Legends and text entries can be included in the data area. The data itself is displayed
