What's your favorite part of attending SAS Global Forum? With the many presentations, networking event and valuable SAS knowledge available, many attendees may find it difficult to pick just one thing. I asked the Best Contributed Paper winners from SAS Global Forum 2013 to share both their most memorable moment from
For several years, there has been interest in calling R from SAS software, primarily because of the large number of special-purpose R packages. The ability to call R from SAS has been available in SAS/IML since 2009. Previous blog posts about R include a video on how to call R
Wavelet analysis is an exciting and relatively new field of study that enables one to extract underlying patterns either from spatially varying or temporally varying data. Pixel values representing the relative brightness and color that constitute an image are an example of spatially varying data, and daily variations of financial
In reference to a previous article on Violin Plots, a reader asked about creating comparative mirrored histograms to compare propensity scores. While I had my own understanding of "Mirrored Histograms", I also looked this up on the web. Google showed many cases of two histograms back to back, either horizontally or vertically.
With the others, I filed into the school gymnasium, my super zoom camera lens at the ready and a nervous smile on my face. Across the room, I caught a glimpse of my unsmiling daughter, and my apprehension grew about how this awards day program would play out for her.
If you’re not an expert on encryption, have no fear! SAS 9.4 has introduced ways to bring stronger encryption to your SAS deployment. The good news is that SAS/SECURE is now a part of Base SAS when you upgrade to SAS 9.4 and is not a separately licensed product anymore.
The holidays are upon us! As you may have experienced, Thanksgiving often serves as the starter pistol for the holiday weight gain marathon. Don’t let holiday collateral damage be the impetus for your New Year’s resolutions this year. A little planning and mindfulness can keep the joy in your season
When I call R from within the SAS/IML language, I often pass parameters from SAS into R. This feature enables me to write general-purpose, reusable, modules that can analyze data from many different data sets. I've previously blogged about how to pass values to SAS procedures from PROC IML by
In using a vector-matrix language such as SAS/IML, MATLAB, or R, one of the challenges for programmers is learning how to vectorize computations. Often it is not intuitive how to program a computation so that you avoid looping over the rows and columns of a matrix. However, there are a
In the first article on Getting Started with GTL, we discussed the basics on how to create a graph using the Graph Template Language. This involved the creation of a "statgraph" template using the TEMPLATE procedure, and then associating data with the template to create the graph using the SGRENDER
Did you submit content for SAS Global Forum 2014? We know content is king, which is why we wanted to get a sampling of the content out on the SAS Global Forum website as soon as possible. However, don't be alarmed if you don't see your presentation listed. You
I'm always trying to find new uses for SAS - this time I've written a proof-of-concept that shows how you might use SAS to create charts that test for color blindness. If nothing else, I think it's a fun example :) First, I did a Google search, and looked at several
In the blink of an eye, summer is gone, fall is slipping by and winter is quickly approaching. Though hopes of snow flurries enter our minds, we often think of winter as a season of germs. Your annual flu shot and regular hand washing are a great start to preventing
Wow did the summer fly by! Now that grad school is over, it’s about time to resume the “it’s all about the data” series. In the last several posts, I tried to lay a foundation for understanding how SAS stores and manages data for use in business intelligence and analytic
While sorting through an old pile of papers, I discovered notes from a 2012 SAS conference that I had attended. Next to the abstract for one presentation, I had scrawled a note to myself that read "BLOG about the incomplete beta function!" Okay, Rick, whatever you say! In statistics, the
I decided this year to get serious about my running. I started recording my distance for every run. I made a SAS data set and generated simple reports. After a few weeks, I set a goal of averaging one marathon a week (3.8 miles per day, 26.2 miles per week,
My daughter's middle school math class recently reviewed how to compute the greatest common factor (GCF) and the least common multiple (LCM) of a set of integers. (The GCF is sometimes called the greatest common divisor, or GCD.) Both algorithms require factoring integers into a product of primes. While helping
Working at SAS, I consider myself fortunate to have the best employee benefits in the industry. That is one of the factors placing SAS as one of the best companies to work for worldwide, and often THE best company to work for in USA. Given that, I was curious to know the kind
Data. Google uses ours every day, and most people aren't concerned. When our government is looking over our shoulders, however, tensions rise quickly. On the one end lies the recent scandals with the National Security Agency (NSA), which is apparently spying on you, me, and Angela Merkel. On the other lies case after case
I enjoyed SESUG 2013 this year and not just because I love hanging out in St. Pete Beach soaking in the sun but also because I was able to “geek out’ with some of my favorite SAS folks. Andrea Zimmerman and Mira Shapiro did an awesome job with the conference.
Microsoft Windows 8 has been with us for a year, and its first major update -- Windows 8.1 -- has just arrived. So how does SAS support these Windows 8 platforms? The answer can be found on support.sas.com in SAS Note 46876. I'll summarize it here: SAS 9.3 and SAS
SAS 9.4 allows you to create html5 output with your graph inline (as part of the html), providing a great way to email your SAS/Graph output! Previously, if you used ods html and dev=png to create graphs, you had to deal with two files -- a png file (containing the graph)
SAS 9.4 has been out for some time now, and all SAS grid computing enthusiasts know that one of the new features is that SAS Workspace Server processes can be directly launched on the grid. (See The Top Four User-Requested Grid Features Delivered with SAS® Grid Manager 9.4.) What does
The mosaic plot is a graphical visualization of a frequency table. In a previous post, I showed how to use the FREQ procedure to create a mosaic plot. This article shows how to create a mosaic plot by using the MOSAICPARM statement in the graph template language (GTL). (The MOSAICPARM
Before that headline really scares you, let me clarify - there hasn't been a single fraud scheme that managed to pull off a $2 trillion haul (yet). However, the fact remains that as rising scams, schemes, the gray market, work under the table and good old tax evasion escalate, as
Mosaic plots (Hartigan and Kleiner, 1981; Friendly, 1994, JASA) are used for exploratory data analysis of categorical data. Mosaic plots have been available for decades in SAS products such as JMP, SAS/INSIGHT, and SAS/IML Studio. However, not all SAS customers have access to these specialized products, so I am pleased
A couple of weeks back I described q way to create a Schedule Chart using the SGPLOT procedure. In that case, I used the HIGHLOW plot to draw bar segments, both for a single and grouped case. A natural extension is to create one with links between each segment. So,
SAS has been used to track the spread of many things, such as wild animals, tornadoes, and money launderers -- but this time I'm using it to track the spread of Walmart stores across the U.S. over time! Since its start in the 1960s, Walmart has grown to be the largest
I was looking at someone else's SAS/IML program when I saw this line of code: y = sqrt(x<>0); The statement uses the element maximum operator (<>) in the SAS/IML language to make sure that negative value are never passed to the square root function. This little trick is a real
Okay, given the title of this article, I might be overselling the content a bit. Read on to see if your life will be transformed. I've just returned from SESUG, and this question came up during one of the presentations. While this tip might seem basic, it was news to
