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
Last week I presented a SAS Talks session for SAS programmers using SAS Enterprise Guide 4.3. It was well attended, which pleased me. You never know how it's going to go with a webinar. People register and sign in, but they are at their desks in their offices/cubicles/homes where distractions
SAS Global Forum, with its long standing history, continues to be the hub and melting pot of brain-stimulating concoctions and eureka moments for SAS users across the globe! This year the magic continues in Las Vegas, at Caesars Palace from April 4 – 7. This series, Snapshot of the Best
I've never met Sy Truong face-to-face. (That will be one of the top items on my SAS Global Forum 2011 to-dos.) I’ve talked with him on Twitter and enjoyed his blog so much that I listed it in an edition of the SAS Tech Report. I’ve even talked with him
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
Last week I talked about how I volunteered to serve as a judge for a middle-school science fair. As I expected, I enjoyed the experience quite a bit, and I hope the students got something positive from me as well. I evaluated several really impressive projects at the 7th grade
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
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.
For all our SAS Global Forum connoisseurs, welcome to this series - Snapshot of the Best Papers of 2010. Despite running for more than three decades, there’s always something new and exciting cooking at SAS Global Forum. Through this series, I will be sharing some of those vibrant flavors from
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
There are over 400 hundred presentations to choose from at SAS Global Forum 2011. With all of these options, it pays to plan ahead. Why not start building your agenda now? The Personal Agenda Builder tool allows you to plan your conference schedule with point and click ease. It has
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
I'm not even at work yet, but I've already learned that SAS has been ranked as the #1 workplace on the Fortune 100 list for 2011. SAS was also number 1 last year in 2010, and has been high on the list since its inception. I'm sure there will be
How many times have you taken a vacation and wished you had a little more time to check out the city? Have you ever extended your stay at a conference to enjoy a "mini-vacation" and peruse the local venues? Well, why not plan ahead and stimulate your mind as well?
Tomorrow I'll be taking a few hours away from work to build something important: the self-esteems of a handful of middle-school-aged children. I'm volunteering as a judge in a middle-school science fair. And even though I'm not a scientist ("computer science" isn't a category), I understand enough about physical science
The SASonality series is about connecting you with SAS users that you may not have taken time to really get to know. Today, I’m going to introduce you to someone that you’ve seen at the SAS regional users group conferences. As you’ll see after reading his interview, he’s created a
In the latest news from the frontier of Internet technology, the NY Times presented an interesting article about the work that high tech providers are doing to ensure maximum system availability. Companies strive for the "5 nines," or 99.999% availability, although a more realistic number is a "4 nine," or
"What is the chance that two people in a room of 20 share initials?" This was the question posed to me by a colleague who had been taking notes at a meeting with 20 people. He recorded each person's initials next to their comments and, upon editing the notes, was
As you’re making your New Year’s Resolutions or reconsidering some that you’ve already put on the list, be sure to think about including SAS Press. Here are our Top 10 Suggestions: Check out the latest SAS Press books. In 2010, we published 20 books. In 2011, we’re on schedule to
A colleague posted some data on his internal SAS blog about key trends in the US Mobile phone industry, as reported by comScore. He graciously shared the data so that I could create a graph that visualizes the trends. The plot visualizes trends in the data: the Android phone is
I think being greedy is a virtue – especially when you are trying to feed your intellectual curiosity! You can satiate that hunger at SAS Global Forum, which offers an unlimited buffet of thought-provoking ideas and discussions. To give you a glimpse of what to expect at Las Vegas this
When your data are in rows, but you need them in columns, use the matrix transpose function or operator. The same advice applies to data in columns that you want to be in rows. For example, the vectors created by the DO function and the index creation operator are row
Interesting article in this quarters sascom magazine by Jeff Ma – the guy behind “bringing down the house” and the movie “21”. After explaining how he felt the power of analytics and statistics was not unlike believing in God, he shared 2 stories where that faith was put to the
One of the best things about writing for the sascom blog is the amazing number of people, both internally and externally, that have reached out to share their stories and perspective, and ask more questions. It’s important for us bloggers to remember that while we may not see published comments
A colleague related the following story: He was taking notes at a meeting that was attended by a fairly large group of people (about 20). As each person made a comment or presented information, he recorded the two-letter initials of the person who spoke. After the meeting was over, he
