How to combine and optimize different types of risk
indicators, in particular with risk indicators of different kinds?
Solution:

for income tax by the NTCA. The aim is to combine a rule

Combine and optimize – Predicting income using Big Data and regression
Level: advanced
Contact person: Jacqueline Kirrane, Ireland
Problem:
How to combine and optimize Big Data/3rd party
information with your predictive model to have a 360°
view of the taxpayer.
Solution:
The Irish revenue has a model using regression to
estimate the income based on Big Data and 3rd party
information. The challenge is to combine and optimize to obtain a good predicted income. It is a smart
way to use Big Data integrated by regression in a predictive model. It is a great challenge to manager
the data quality with a vast number of information sources.
