It's midyear, and management has decided that a new publication is a great way to highlight the work of a group of people within the organization to external audiences. "We'll keep costs down by doing the design and layout ourselves. We just need to buy the software licenses." Money is

It's the start of a new year. Have you made a resolution to be a better data analyst? A better SAS statistical programmer? To learn more about multivariate statistics? What better way to start the New Year than to read (or re-read!) the top 12 articles for statistical programmers from
Look at what arrived in the mail room this morning! Of course, I was expecting it sometime in January...but not first thing! Here's to early deliveries...perhaps this will set the tone for all of my projects in the new year.
In part 1 of my thoughts about analytics maturity, I deferred talking about issues related to the actual assessment of your organization’s level. Today I intend to detail some of the ways my peers and I are thinking about analytical maturity, comment on scales in use today, and address some
The Lancaster Centre for Forecasting is led by two of my favorites in the forecasting world, Robert Fildes and Sven Crone. The Centre is home to cutting edge research and consulting, covering the range of forecasting models and methods, as well as real-world forecasting process. The Centre has announced a
Are you ready for the upcoming International Year of Statistics? I have prepared myself by doing a correspondence analysis. Excusez-moi? Correspondence analysis is a technique that has been very popular in France and is therefore sometimes referred to as French Statistics. Correspondence analysis is a technique for categorical data analysis.
I used "Dropbox" in the title for this post, but these techniques can be used for other cloud-based file sharing services, such as GitHub and Google Drive. Using PROC HTTP (added in SAS 9.2), you can easily access any "cloud-based" file as long as you have a public link to
Watching our nation approach the "fiscal cliff", and the dire predictions if we truly drive off it like the last scene in Thelma and Louise, has sharpened my view of the potential risks that huge gaps of fraud and abuse present to all of us. One of the key lessons

'Twas the week before Christmas, and all through the world ... dot-matrix printers were humming as Santa's naughty/nice list was unfurled... Can you imagine what it must have been like years ago when Santa had to maintain his naughty/nice list by hand, with a feather quill pen?!? Or even these
Joyce Norris-Montanari declares this the perfect time to prepare your data for 2013. See what her plans entail.
The SGPANEL procedure is used to create panelled graphics based on classification variables. The panelled cells are generated starting from either the top left (the default) or the bottom left of the panel, controllable by the START option. Currently, the ordering of the cells is determined by two criteria: 1.
In my previous post, I described how to implement an iterated function system (IFS) in the SAS/IML language to draw fractals. I used the famous Barnsley fern example to illustrate the technique. At the end of the article I issued a challenge: can you construct an IFS whose fractal attractor
Police Departments across the country are under constant scrutiny by elected officials, the media and the public to reduce crime, control costs, engage the public, always be accessible and, most important, always be courteous and professional. Police departments that demonstrate excellence in these areas can achieve accreditation by The Commission
Fractals. If you grew up in the 1980s or '90s and were interested in math and computers, chances are you played with computer generation of fractals. Who knows how many hours of computer time was spent computing Mandelbrot sets and Julia sets to ever-increasing resolutions? When I was a kid,

Naomi Robbins has posted a contest, part 1 of which is to submit alternative representations for the following graph: Clearly, usage of two pie charts to represent the share of the B2B and B2C referrals will invite many responses. To create the graph, I took the data shown in the Pie Charts themselves, so we are using percent
Several years ago my mom, bless her heart, bought a cell phone. Now, my mom is not what one would call “tech-savvy”. She has had the same car forever, same furniture for 25 years (well, she did get it reupholstered), even the same pots and pans that came as wedding
As rain settles in over the green fields of England, I’ve been reading the Times Higher Education (THE) periodical. It’s always a lively read, as it invariably takes the part of untenured junior lecturers in any dispute. It is also very well researched and informed. This week’s THE edition has
While I'm waiting for the next "data intense" event to show up in the news (so I can blog some SAS graphs about it), I thought I'd share a few fun SAS graphs in the spirit of the holiday season! Please don't hold me to too high of graphical "best practices"
In a recent article on efficient simulation from a truncated distribution, I wrote some SAS/IML code that used the LOC function to find and exclude observations that satisfy some criterion. Some readers came up with an alternative algorithm that uses the REMOVE function instead of subscripts. I remarked in a

I live in the South, but was raised by Midwestern Catholics from rural Minnesota. Think Jeff Foxworthy meets Fargo. A few of the great things that I have learned about folks in the South is their incredible politeness even when they are really saying, "Wow, what in the world are
Independent contractor. Two very simple words that have a dramatic impact on businesses, workers, and government programs. While most people have a basic understanding of the term, they often have very little understanding of the laws governing it, which vary significantly program by program and state by state. This has
It seemed like an easy task. A SAS user asked me how to use the SGPLOT procedure to create a bar chart where the vertical axis shows percentages instead of counts. I assumed that there was some simple option that would change the scale of the vertical axis from counts
There are two activities which, when taken in combination, have occupied the vast majority of my working hours for the past 20 years: writing computer programs and writing...well, just writing. During my college years I completed my degree with a double-major: Computer Science and English. (My English degree has a
Blogger Dylan Jones offers 3 tips for more effective data profiling.
If you haven’t heard of an APCD, it’s one of those acronyms you need to know. All-Payer Claims Databases are simply databases that consist of claims data from all health care payers in a given state. This includes private payers such as Blue Cross Blue Shield, and public payers such
Frequently someone will post a question to the SAS Support Community that says something like this: I am trying to do [statistical task]and SAS issues an error and reports that my correlation matrix is not positive definite. What is going on and how can I complete [the task]? The statistical
Several weeks ago, South Carolina was the victim of what some experts believe to be the largest cyber-attack against a state tax department in history. Approximately 3.6 million personal South Carolina income tax returns were exposed, and nearly 657,000 businesses compromised, in an international hacking attack. Coincidentally, SAS and the SC
