what is a customer risk rating model used for
to measure the potential money laundering and terrorist financing risk of a customer
what are the 5 steps in model development
- scope and data collection
- preliminary hypothesis model
- review and refine
- model validation and approval
- implementation
what are the 5 steps in creating the preliminary hypothesis model
- model construction
- profile data to understand distribution and data quality
- features
- build a hypothesis model with scores assigned judgementally.
- generate sample cases that are statistically significant using the hypothesis model.
what are the 9 aspects of data quality
- complete
- coherent
- consistent
- current
- accurate
- unique
- legally valid
- traceable
- bias
what are two phases of the feature step in the preliminary model hypothesis and what do they entail
- feature engineering: include and engineer all possible features that could improve model accuracy
- feature selection: reduce the number of features as much as possible without compromising predictive ability.
what are 3 techniques that can be used in feature selection
- judgment based scorecard
- logistical regression
- advanced regression
what are the five types of bias
selection
exclusion
reporting
recall
observer
what is selection bias and how can it be fixed
a certain individual is more likely to be selected than another
fix: probabilistic sampling methods
what is exclusion bias and how can it be fixed
certain individuals are systematically excluded
fix: weighting to adjust for misrepresentation, supplementary data
what is reporting bias and how can it be fixed
certain types of observations are more likely to be reported
fix: reweighing, probabilistic sampling methods
what is recall bias and how can it be fixed
difference in the accuracy of participants recollection in events
fix: using a case-control study
what is observer bias and how can it be fixed?
the researcher subconsciously influences the data collection
fix: ensure the modellers are objective
