Each spring and fall, I start clearing out the kid's small clothes, old toys, etc. It can sometimes go too far and reach into my "digital pack-rat" issues. (Wait, what does that mean? Well, just ask the person who last week requested detail on a project I worked 3 years
The North East SAS Users Group Conference (NESUG) will be held November 11-14, in Baltimore, Maryland. I’m psyched to be attending this year, and hope I’ll see you there.
In the previous post on Violin Plots, we discussed the process to create custom density plots. This work was done in collaboration with SAS user James Marcus. This is the second installment on the same topic - Creating Density Strip Plots. We will use the same data and process to compute
We all have some sort of intuitive idea of what time series data is – it’s a bunch of measurements or observations that are marked by a time stamp – we know when the measurement was taken, as well as what was measured. This natural temporal ordering of the data
As part of the Friday's Innovation Inspiration (FII) series, I've decided to present a few SAS techniques and problem solvers that you labeled as innovative or 'inspirational'. These are pretty easy to find: I've done some digging through the Best Contributed Papers. I know you haven't read them all, so
K-12 education reform and policy has seen a recent surge in the cinema with "Waiting for Superman," "The Lottery," and this fall’s "Won't Back Down.” However, if you can’t bring yourself to spend $9.00+ at the box office, or (like me) have a hard time finding babysitters to even get
You’ve just started a new job as SAS administrator, and there’s no documentation. How do you know which SAS products are installed? Where they are deployed? Where do the data and programs reside? Brian Varney tells us that SAS administrators often run into undocumented environments whenever they begin working in a new
The determinant of a matrix arises in many statistical computations, such as in estimating parameters that fit a distribution to multivariate data. For example, if you are using a log-likelihood function to fit a multivariate normal distribution, the formula for the log-likelihood involves the expression log(det(Σ)), where Σ is the
Over the past month or more, I have been in a conversation with SAS user James Marcus, on creation of some new displays for visual communication of uncertainty. These include display of densities using a "Violin" plot, "Density Strips" and more. With his permission, I can share some of the
I work on a variety of projects at SAS, most of which require some level of team collaboration in source management systems. Due to the many technologies that we work with, SAS developers use different source management tools for different purposes. I've got projects in CVS, Subversion, and Git. When
Our SAS Users Group regional road trip is coming to an end. Final destination -Baltimore, MD. That will be the site of the Northeast SAS Users Group regional conference November 11-14. More than 500 users are expected to come together to share ideas, learn from experts, and increase their SAS
BASE SAS users are already familiar with the autoexec file. This is a .sas file that typically resides in the installation folder of the SAS executable. Instructions for setting it up in UNIX, Windows, and other environments is readily available on the SAS website. In SAS BI configurations there are
This week's tip is from Professor Willbann D. Terpening and his book Statistical Analysis for Business Using JMP. If you're intrigued by the following excerpt, visit Terpening's author page for additional bonus book content. And take a look at his previously featured tip The Student t-distribution, on this blog: The following excerpt is from
What do disaster planning and baseball have in common? (Cue Cubs fans, "We plan on every season being a disaster!") Bear with me... Watching game 1 of the World Series reminded me of the time I took my son to AT&T Park to see the Giants play. It was the day
Never been to Houston? November 5-6 is perfect for your first trip. Make plans to see some of what the fourth-largest city in the US has to offer; there are some famous visitor destinations - and some not well-known. The South Central SAS Users group is holding its annual SAS Educational Forum in this
