One of my New Year's resolutions is to learn a new area of statistics. I'm off to a good start, because I recently investigated an issue which started me thinking about spatial statistics—a branch of statistics that I have never formally studied. During the investigation, I asked myself: Given an
SAS’ Contact Center has been an integral part of our company for over ten years. Composed of fifteen employees, our team services both internal and external customers. Internally we work with our marketing department to provide outbound call support for campaigns and with our sales organization to qualify and route
As Cat Truxillo points out in her recent blog post, some SAS procedures require data to be in a "long" (as opposed to "wide") format. Cat uses a DATA step to convert the data from wide to long format. Although there is nothing wrong with this approach, I prefer to
I sing in the SAS-sponsored VocalMotion show choir. It's like an adult version of Glee, except we have more pregnancies and fewer slushie attacks. For many musical numbers, the choreographer arranges the 20 performers on stage in an orderly manner, such as four rows of five singers. But every once
I have recently had the great opportunity to be a part of a very special project called the North Carolina Bio-Preparedness Collaborative (NCB-Prepared) It is a public-private partnership that includes the University of North Carolina at Chapel Hill (UNC), North Carolina State University, and SAS, with support from the US
A histogram displays the number of points that fall into a specified set of bins. This blog post shows how to efficiently compute a SAS/IML vector that contains those counts. I stress the word "efficiently" because, as is often the case, a SAS/IML programmer has a variety of ways to
Anyone who knows me well, knows I believe in the power of three. I know I am not the first to realize the near mystical properties of this tool, and as a marketer and leader, I do my best to take advantage of it. Lions, and Tigers and Bears; the
Have you ever wanted to compute the exact value of a really big number such as 200! = 200*199*...*2*1? You can do it—if you're willing to put forth some programming effort. This blog post shows you how. Jiangtang Hu's recent blog discusses his quest to compute large factorials in many programming languages.
Who doesn’t like bargains? I’m sure you will all agree that good quality at a next-to-nothing cost is irresistible. My recent Dollarama run had me ecstatic about the gloves that come in all colours, styles and sizes for just over a dollar. (Fact: big retail stores charge over 10 times
The other day I needed to check that a sequence of numerical values was in strictly increasing order. My first thought was to sort the values and compare the sorted and original values, but I quickly discarded that approach because it does not detect duplicate values in a montonic (nondecreasing)
It has become routine. For the 14th straight time – which is every year since its first publication in 1998 – SAS has made the Fortune “100 Best Companies to Work For” list. This includes eight appearances in the top ten, and in 2011, for the second year in a
Okay…I don’t usually do the rah-rah SAS stuff, but it was a really great week here and I wanted to share. The Analytic Cheerleader is getting out her pom-poms and cheering for SAS! Since I’ve been a SAS employee for exactly 3 months, I thought it was a good time
In a previous post, I described ways to create SAS/IML vectors that contain uniformly spaced values. The methods did not involve writing any loops. This post describes how to perform a similar operation: creating evenly spaced values on a two-dimensional grid. The DATA step solution is simple, but an efficient
There is nothing quite like third-party validation to complete the picture when telling a story. A quick peek at our Customer Success Stories page and any number of Analyst Reports tell versions of the SAS story as a great source of business solutions in ways that we could never do
Seems I rarely write blog posts unless I'm waiting around for numbers to put in our annual financial-results announcement. Why is that? In the calm before the rush to report revenue, before the new year gets under way, I have time to think. And I start thinking about how great
