Super Extra Large Size
Hyper cube Multi Dimension
Text,ASCII,Url etc. High Frequency
Near Real Time
Spatial Temporal Lot of Variable

8. Technical Statistics Method Currently Used
In business analytic process - several statistical tools used for:
1. Develop basic model: Support other model, lifetime valuation and segmentation (K-
means cluster, Cox Regress)
2. Econometric Model : Doing what if analysis, interpolation and extrapolation (forecasting
time series regression)
3. Acquisitions: Predatory acquisition model, best replication
4. Retention : move to competitor prevention (logit reg, CART, C5.0, Quest, CHAID, SVM
Ridge)
5. Stimulation : Propensity product
Criteria to select best model : Logic business, Best Lift, Best Gain, Small gap are between
wizard and ROC curve.
How its run:
1. Factory Wise : Up to several hundred models per year
2. Automatic scheduled .
3. Real time response.

9. Understanding Business Questions
1. We must make specific customize product /offer/policy for every distinct person /
company Base segmentation
2. I need to know product purchasing cycle to manage crosseling Sequential market
basket
3. Can we identify customer that will be go to another competitor product next month
then let us identify what offer that fit for retain them dependency model with
binary/ordinal/multi classifier
4. We must find out what offer that fit to retain customer in every segment and give us
(+) ROI Experimental design + Financial Calc
5. How many base will be retained per month for next 1 year, how many revenue will be
generated from them ridge & financial valuation (FV,PV)
6. We will give special treatment for customer that high circle of friend, centre from that
link/network or bridge from their network Social Networks/Graph Theory

10. Deliver Result
1. Problem solving mostly unique and simple
2. Board of decision makers only need final result with reasonable
:logic process and result.
3. Ability to presenting result in simple and clear manner
1. Slide 5-10
2. Begin slide with 1 slide resume of analysis and followed by 1
slide of simple methodology data extraction, logic to solving
problem, variable used, sample used
3. Clear and clear color pattern background of slide
4. Show only pointers not text line /text book

11. Conclusion
1. Opportunity for statistician in
next several decade still wide
open .
