Defying Experts, Rogue Computer Code Still Lurks

New York Times (08/26/09)

Markoff, John

in-database data mining

I have been building data mining solutions within relational databases. Almost every process is done within the database environment. We enjoy the functions provided by databases: security, scalability, analytic functions, manageability, easy model deployment, SQL, etc. Since data mining is done on the server side, the crash of my laptop hard drive has minimum impact on my work (it happened twice in the last two years).

Determining Seasonality using PROC X11 in SAS

Determining seasonality, deseasonlizing seasonal data, getting trend indices, getting seasonality indices have always been a boring nightmare for Analysts when it comes to analysing percentage increase in some parameter like sales, visits, frauds etc., negating the effects due to seasonality. All the above mentioned so called "NIGHTMARES"can be easily handled with the powerful but less used SAS procedure called PROC X11.



PROC X11 works as below,

It splits the actual data into… Continue

And You Thought a Prescription Was Private - Data Mining of Prescription Records

From Milt Freudenheim, New York Times



MORE than 10 years after she tried without success to have a baby, Marcy Campbell Krinsk is still receiving painful reminders in her mail. The ads and promotions started after she bought fertility drugs at a pharmacy in San Diego.



Marketers got hold of her name, and she found coupons and samples in her mail that shadowed the growth of an imaginary child — at first, for Pampers and baby formula, then for discounts on family photos, and… Continue

Prediction + understanding

In my view, predictive models can be powerful business tools, but they have the potential to lead us into a false belief that because we can predict something on the basis of mathematical relationships, we understand what we’re predicting. We might also lapse into an expectation that “prediction” based on past behavior is in fact… Continue

It happens

One of the most common obstacles organizations face with data quality initiatives is that many initial attempts end in failure. Some fail because of lofty expectations, unmanaged scope creep, and the unrealistic perspective that data quality problems can be permanently “fixed” by a one-time project as opposed to needing a sustained program. However,… Continue
