Have you ever submitted a SAS program or query only to immediately regret it? It usually happens just as you finish clicking the mouse or lift your finger from the F8 key: you realize that your program has a horrible flaw that's going to make it run for hours or
The SAS internal discussion boards are always full of fascinating topics, some of which are even decipherable to a non-Ph.D. in statistics like me. A recent topic involved how to calculate the benefits of good forecasting software, and my colleague Robin Way offered an interesting perspective that he allowed me
Personally, I don’t get Twitter. I have an account (mvgilliland) for anyone interested in not hearing any tweets from me. I follow a few people and have a few followers (including some that aren't porn bots) -- but what is the point? Does anyone really care that I’m out hanging
In a previous posting I showed an example of how you can use the GKPI procedure in SAS 9.2 to create dashboard-quality charts. Here's a more formal sample that you can use, including a custom task that you can use in SAS Enterprise Guide 4.2 to point-and-click your way the
Geoff posted a nice article on his blog about how you can read and write Microsoft Excel spreadsheets programmatically from within SAS, without using DDE. I've previously written about how it's difficult to continue using DDE from SAS when you have a distributed environment (SAS on a server machine, Excel
The Summer 2009 issue of Foresight is now available, and features a section on “Rethinking the Ways We Forecast.” Here is Editor Len Tashman’s preview: Are traditional forecasting tools suitable for predicting complex systems like the economy and the global climate? Basically, no, argue David Orrell and Patrick McSharry: such
On a Monday July 20 segment of consumer advocate Clark Howard’s radio show, Clark discussed the common practice of hidden payments to influential bloggers. Apparently these high-tech shills pocket the payola, and then make favorable postings about particular products or services. According to Clark, there are new rules to prevent
Aren’t the internets wonderful? Just today I was trying to find the antonym of “naïve” and came across several terrific choices (sophisticated, worldly, well-informed, and intelligent) and one that didn’t make any sense (svelte???). However, upon further review at Merriam-Webster.com, I discovered that in addition to slender, lithe, and sleek
In April 2009, Google published a draft research paper “Predicting the Present with Google Trends,” by Google’s Chief Economist Hal Varian and Decision Support Engineering Analyst Hyungyoung Choi. The paper is available for download in an April 2 posting by Varian and Choy on the Google Research Blog that has
With apologies to Johnnie Cochran and Joyce Kilmer : “If the model do fit, it don’t prove ****” This was the warning from Trick #1. As a forecaster your job is to produce forecasts – as good as they can reasonably be expected to be – not to fit models
The Spring 2009 Foresight feature on assessing forecastability is a must-read for anyone who gets yelled at for having lousy forecasts. (It should also be read by those who do the yelling, but you’d have to be living in Neverland to believe that will ever happen.) As I promised in
Today I welcome guest blogger Len Tashman, Editor of Foresight: The International Journal of Applied Forecasting. I’ve been a big fan of Foresight since its inception in 2005, and the Spring 2009 issue contains a special feature on a topic close to my heart -- assessing forecastability. Here is Len’s
Tricks aren’t just for kids (or Louisiana senators or New York governors for that matter). Tricks are the lifeblood for many a forecasting software salesperson. Why admit that forecasting is difficult, that most things can’t be forecast as accurately as we would like, or that your software has the statistical
Here is the first of what I hope to be many guest postings from my colleagues here at SAS. Today Snurre Jensen, Business Advisor from SAS Denmark, writes about his recent encounter with a blog about dealing with demand changes in SAP APO. From Snurre: In my ongoing quest for
What do men really want? What do women really want? If you seek answers to these eternal questions go watch Oprah or Dr. Phil – I don’t really care. They are not nearly as interesting as the question: What do forecasting software buyers really want? Organizations spend millions of dollars
