Page 3: Predictive Analytics - A Primer

……….we take as much historical data from racing as we can and try to find the

things that are important for predicting the outcome of future races. Once

we find those things (in some cases we can be working with tens of

thousands of combinations of variables), we then run the models against a

test set of races and look at the results. We then look at the races that we

predicted correctly and work out what things made that possible for those

predicted correctly and work out what things made that possible for those

particular races. This is how we come up with the Bet Index. This

information is then fed back into the models to make them better

What is Predictive Analytics ?

“Use historical data to make certain predictions for the future”

Hindsight“What is happening ?”

Insight“Why is it happening ?”

• Typical MIS or BI

• Cognos; Business Objects; Hyperion; ProClarity; etc

• Largely backward looking

• Referred to by many folks as ‘Analytics’ although it is not

• Business analysis

• behavior analysis; trends; etc

• Gives us insights on what is happening and why

• Predictive Analytics; forecasting; optimization, etc

• Uses past behavior to predict future outcomes

• Game changing

• Forward-looking

Page 5: Predictive Analytics - A Primer

• Commonly used when the objective is to predict a binary outcome

• Used to forecast outcomes that are of a continuous nature

• Used to bucket or ‘cluster’ like things

• Each member in a cluster

Some types of Predictive Analytics

• Example: will Customer X respond or not respond to my marketing offer

• Example: What is the chance Customer Y will dis-enroll in the next 12 months

continuous nature

• Example: how much will this Customer Y spend in the next month?

• Example: movement of the S&P 500 index on a weekly basis for the next 12 weeks

• Each member in a cluster is very similar to another member in same cluster; but very different from a member in a different cluster

• Example: Customers in a particular segment have similar behaviors

Business Objective

I want to identify which Customers will ‘attrite’ so that I can take some

proactive actions

All Customers? Or just new Customers???

Attrite today / tomorrow / next month / etc

7

I want to predict which of my high tenure Customers will ‘attrite’

or ‘churn’ in the next 6 months

Attrite today / tomorrow / next month / etc

What is attrition to me? No activity for 6

months / 2 months / etc

Output of Modeling Process

Every Customer has a unique ‘Score’ that captures the essence of

what is being modeled.

The ‘Score’ is essentially the ‘probability’ of something happening scaled in a

pre-defined fashion; having an upper- and an lower-bound

11

pre-defined fashion; having an upper- and an lower-bound

Called a ‘Score-card’

For Example:

1. Customer #17523 has a score of 769; translating to a 90% probability of ‘churning’ in the next 6

months

2. Household # 845 has a score of 423; translating to a 36% chance of accepting the offer for a

magazine if sent a Direct mail Offer
