6. “
The quantitative analysis isn’t magic—but it
is normally done with a lot of past data, a
little statistical wizardry, and some important
assumptions.

8. DATA
Lack of good data is
the most common
barrier to
organizations
seeking to employ
predictive analytics.
If you have multiple
channels or customer
touchpoints, you need
to make sure that they
capture data on
customer purchases in
the same way your
previous channels
did.
9. STATISTICS
Regression analysis in its various forms is the primary tool that
organizations use for predictive analytics.
The analyst performs a regression analysis to see just how correlated
each variable is; this usually requires some iteration to find the right
combination of variables and the best model.
It’s quite likely that the high scoring customers will want to buy the
product—assuming the analyst did the statistical work well and that
the data were of good quality.
11. WHAT MAKES ASSUMPTIONS
INVALID?
TIME:
If your model was created
several years ago, it may no
longer accurately predict
current behaviour. The
greater the elapsed time, the
more likely customer
behaviour has changed.
If the analyst didn’t
include a key variable in
the model, and that
variable has changed
substantially over time.
14. A MANAGER SHOULD SEEK THE
ASNWER OF THE FOLLOWING
QUESTIONS FROM HIS TEAM OF
DATA ANALYSTS:
15. Can you tell me something about the source of data you used in
your analysis?
Are you sure the sample data are representative of the
population?
Are there any outliers in your data distribution? How did they
affect the results?
What assumptions are behind your analysis?
Are there any conditions that would make your assumptions
