There is a huge inequality in the way the economy has played out among people I know. Business is good and has been getting better all year for me. My friend Jake is doing great. He was an anesthesiologist and several years ago became board-certified in geriatrics. He loves working with older people and his…
So I say, “There may be some useful information in the text fields. For example, people who use credit to buy commodities, such as meat may differ from people who buy finished goods like clothing who may differ from people who purchase machinery on credit. Perhaps you may want to consider some kind of clustering.”…
No, this is not a post about politics or life-hacking, although the same title could apply in either case. I am talking about statistical power. People often ask me what the power of a test is, but the problem is that they are asking the wrong question. Power is not a single number. I understand…
In the past, when I had to do any type of parsing of text, I wrote my own code with a zillion SUBSTR functions and IF statements and it did the job but it was *so-o-o ugly and painful that I never even considered including text mining in any courses I taught. I looked into…

After over a quarter of a century of experience working as a statistical consultant in a wide array of settings, it’s safe to say that a large proportion of the statistics presentations cover topics I have been over before. Still, even if it is a technique I’ve used many times, I almost always come across…
Two years ago, I said that data visualization was the next big thing. I also said that people would stick with SAS because it was easier to use and there are more people who DON’T want to be programmers than do. Fast forward to 2012 and Visual Analytics is all over the place. SAS On-Demand,…
The taiko drumming on trash cans at the opening ceremony was kind of cool, but being a true geek I have to say the cool thing of the day goes to Visual Analytics. By the way, ten brownie points and kudos to whoever had the bright idea of having the SAS demo room open on…
SAS Global Forum has the usual required conference amenities. There is a nice hotel. There is swag. See photo below received by knowing trivia answers. Hint: A good place to find the trivia answers in advance is the SAS users blog. It is also good to know the name of the SAS Global Forum chair…
