If you're like most large organizations, you've got a bunch of business intelligence and analytic applications at your fingertips. In my prior organization, a large insurance company, I believe the magic number of tools that the organization had to support was north of 40. No kidding. Now, this is a
I connect to more SAS server environments than your average SAS user. In a given week, I probably run SAS Enterprise Guide connecting to at least five different Windows-based servers, a few Unix-based servers, and maybe even a z/OS machine as well. With that many SAS environments, I'm bound to
Sample covariance matrices and correlation matrices are used frequently in multivariate statistics. This post shows how to compute these matrices in SAS and use them in a SAS/IML program. There are two ways to compute these matrices: Compute the covariance and correlation with PROC CORR and read the results into
I enjoy reading about the Le Monde puzzles (and other topics!) at Christian Robert's blog. Recently he asked how to convert a number with s digits into a numerical vector where each element of the vector contains the corresponding digit (by place value). For example, if the number is 4321,
Computer science is more than the pursuit of "let's see what we can make this computer do." If that's your only goal, then you might make a fine computer geek, but a lousy computer scientist. In her blog post for Computer Science Education Week, Caroline McCullen reminds us that computer
I’ll never forget the first time many years ago that I saw the Dilbert cartoon by Scott Adams showing Dilbert getting transferred to marketing, approaching a doorway that says “Welcome to Marketing - Two Drink Minimum.” I found it so funny until I realized that my friends in IT and
A professional acquaintance and an expert in statistics once told me that if you don't understand how to perform the process of analytics through programming - the creation of the data flow, the transformation of the variables and the development of the statistical procedure - then you had no business
The SAS/IML language enables you to perform matrix-vector computations. However, it also provides a convenient "shorthand notation" that enables you to perform elementwise operation on rows or columns in a natural way. You might know that the SAS/IML language supports subscript reduction operators to compute basic rowwise or columnwise quantities.
I'm back in the office after two enjoyable days at the Internet Summit in Raleigh, NC. (I hadn't seen that many nerds since the family reunion on my dad's side.) Among the many good sessions was one about building your blog audience by making the blog more search friendly. The
My last post was a criticism of a statistical graph that appeared in Bloomberg Businessweek. Criticism is easy. Analysis is harder. In this post I re-analyze the data to present two graphics that I think should have replaced the one graphic in Businessweek. You can download the SAS program that
Have you used multivariate procedures in SAS and wanted to save out scores? Some procedures, such as FACTOR, CANDISC, CANCORR, PRINCOMP, and others have an OUT= option to save scores to the input data set. However, to score a new data set, or to perform scoring with multivariate procedures that
It seems like each week brings news announcing yet another software vendor acquisition by one of the giant software conglomerates. This approach of purchasing a specific capability to fit into the ever growing portfolio of technology does not show signs of stopping in the near future. Matter of fact, several
In April, I wrote 12 ways to write a conference blog post. It's one of those posts that I continue to share and often see others reference as well. One thing that might be implied in that post but isn't overtly stated is something of a golden rule for for
This is a continuation of my last post, Lunchtime Reading—4 Steps to Getting Started with a Lead Nurturing System. SAS’ recently implemented Lead Nurturing System is a calculated means to better serve our prospects and customers, while moving us along a continuum of turning our marketing data into more of
Author note: I'm "replaying" this post in honor of Computer Science Education Week. It originally appeared here over 3 years ago. Today was "career day" in my daughter's 3rd grade classroom. A few privileged parents were invited to attend and answer questions about their professions, press-conference style. Among those on
