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
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
"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
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
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
Did you know that our tongue possesses an average of 10,000 taste buds to differentiate between the myriad flavors? Luckily for you, at SAS Global Forum we have a wonderful array of flavors to appease your every taste bud. There is something special for everyone in the new series that
SAS/IML software is often used for sampling and simulation studies. For simulating data from univariate distributions, the RANDSEED and RANDGEN subroutines suffice to sample from a wide range of distributions. (I use the terms "sampling from a distribution" and "simulating data from a distribution" interchangeably.) For multivariate simulations, the IMLMLIB
AUTOEXEC.SAS wasn't enough for you. Yes, it's a sure-fire way to run SAS statements (such as LIBNAME assignments or macro definitions) whenever you start your SAS session, but you found it has limitations when used in configurations with lots of users who connect with SAS Enterprise Guide. Limitations such as:
It is often useful to create a vector with elements that follow an arithmetic sequence. For example, {1, 2, 3, 4} and {10, 30, 50, 70} are vectors with evenly spaced values. This post describes several ways to create vectors such as these. The SAS/IML language has two ways to
Computing probabilities can be tricky. And if you are a statistician and you get them wrong, you feel pretty foolish. That's why I like to run a quick simulation just to make sure that the numbers that I think are correct are, in fact, correct. My last post of 2010
Appetizers usually play a significant role in ensuring a good restaurant experience…right? A good appetizer whets your appetite and gets you psyched and excited for the main course! This series of blog posts aims to do just that…whet your appetite for what’s in store at SAS Global Forum. In the
I'm pleased to announce that I'll be presenting another SAS Talks session on January 27th, 2011 (this month!). This talk will focus on the cool stuff in SAS Enterprise Guide 4.3, especially for the SAS programmer. Here's some of what you'll learn about: Syntax suggestion and autocomplete for the SAS
The Junk Chart blog discusses problems with a chart which (poorly) presents statistics on the prevalence of shark attacks by different species. Here is the same data presented by overlaying two bar charts by using the SGPLOT procedure. I think this approach works well because the number of deaths is
Over at the SAS/IML Discussion Forum, someone posted an interesting question about how to create a special matrix that contains all combinations of zeros and ones for a given size. Specifically, the problem is as follows. Given an integer n ≥ 1, produce a matrix with 2n rows and n
Most people don’t think about government when they hear the word “innovation”, but it’s happening, and has been since long before “The Great Recession.” However, the current economic conditions have certainly moved things along. Government responds very similarly to private industry when faced with challenges. SAS manages to do relatively
It's a New Year and I'm ready to make some resolutions. Last year I launched this blog with my Hello, World post in which I said: In this blog I intend to discuss, describe, and disseminate ideas related to statistical programming with the SAS/IML language.... I will present tips and
In many families, siblings draw names so that each family member and spouse gives and receives exactly one present. This year there was a little bit of controversy when a family member noticed that once again she was assigned to give presents to me. This post includes my response to
This is the fifth post in the SASonality series. In this week’s post, I’ve interviewed Rick Langston, a man most SAS users have met or read about. He’s been with SAS for 30 years and attended nearly every SUGI/SAS Global Forum. In the photo at the right, Rick is the
If outliers could scream, would we be so cavalier about removing them from our history, and excluding them from our statistical forecasting models? Well, maybe we would – if they screamed all the time, and for no good reason. (This sentiment is adapted from my favorite of the many Deep
It's almost 2011, so let's reflect on the top 11 posts (by number of visits in 2010) on this blog. Not all of these posts were written in 2010; in fact, some of these date back to 2007. But apparently they are oldies and goodies. 1. SAS 9.2 and SAS
