Business Analytics
The Time is Still Right for Analytics
• Executives are looking for new sources of advantage and differentiation
• They have more data about their businesses than ever before
• A new generation of technically literate executives is coming into
organizations
• The ability to make sense of data through computers and software has
finally come of age

What is Data Mining?
 “…the exploration and analysis, by automatic or semiautomatic
means, of large quantities of data in order to discover meaningful
patterns and rules” -- Berry & Linoff*
 “…the process of discovering meaningful new correlations,
patterns and trends by sifting through large amounts of data stored
in repositories, using pattern recognition technologies as well as
statistical and mathematical techniques.” --Gartner Group
 “Predictive analytics is a set of business intelligence
technologies that uncovers relationships and patterns within large
volumes of data that can be used to predict behavior and events.”
-- TDWI Research**

Business Analytics
Time To Change the 2 Cultures* Clash
Top-Down Approaches:
Bottom-Up Approaches:
Query, Search
Data Mining, Text Mining
 A Statistical Approach can
involve a user forming a theory
about a possible relationship in
a database and converting that
to a hypothesis and testing
that hypothesis using a
statistical method. It is a
manual, user-driven, top-down
approach to data analysis.

The difference with data
mining (which includes
multivariate statistical models!)
is that the interrogation of the
data is done by the data
mining method--rather than by
the user. It is a data-driven,
self-organizing, bottom-up
approach to data analysis
 Source DM Review
Statisticians can use their favorite methods from within Modeler 14 and Data Miners
can broaden their capabilities by invoking statistical methods from Statistics 18

The Kinds of Questions that Data Mining Can Answer
• Based on the percussion beat, what genre of music is this?
• Which books of the New Testament have the same author?
• What class of astronomical object is this image?
• Which genes express when drug B prevents the rejection of a transplanted organ?
• Which transformer in a grid is likely to fail due to a breakdown of its dielectric?
• What combination of repair parts are needed at worldwide aircraft service centers?
• To which of 4 products will a customer respond in a marketing campaign?
• How much of a costume should store # 7005 stock for Halloween this year?
• Which annuity holder will prematurely surrender their policy?
• Which physician will prescribe more of this acid reflux drug than an alternative?

Should I Teach Data Mining Skills in My Department?
In addition, as the U.S. business environment becomes increasingly competitive and
organizations strive to increase efficiency and reduce costs through the use of information
technology, computer and mathematical science occupations will see strong
employment growth.“ -- 2008—2018 Outlook in Monthly Labor Review, Nov. 2009, p.83
