|
FCI
|
Order statistics
|
Nonlinear function (like portfolio variance)
|
Financial cycle theory, previous literature, without
empirical evaluation of the variable characteristics before the crisis.
|
Takes correlation into consideration, graphical
representation, no problems with statistical filters regarding data
transformation, robustness due to scaling variables.
|
Lack of objective data selection criteria, variable
selection affects the dynamics of the indicator, harder to communicate, hart
to evaluate the results
|
|
Cyclogram
|
Max min or based on percentiles of distribution
|
Average, weighted average
|
Previous experience with variable dynamics tracking.
|
Graphical representation, no problems with
statistical filters regarding data transformation, easy aggregation and
interpretation
|
|
d-SRI
|
Normalization, standardization or max min
|
Early warning models of signaling crisis.
|
Data selection criteria, simple aggregation and
interpretation, robust9
|
Correlations not observed, biased results for one
country analysis
|
|
PCA
|
Normalization, standardization
|
Weighted average based on loadings on the first
principal component
|
Any of the previous three main approaches
|
Simple aggregation
|
Assumptions of PCA analysis, changing correlations,
bad predictive power of the first principal component.
|
|
Geometric average
|
Normalization, standardization
|
Geometric average formula
|
Hard to interpret results in economic way,
correlations not observed, depends on the main method of aggregation,
negative values in data.
|
|
RMS
|
Normalization, standardization
|
Root mean square formula
|
Hard to interpret results in economic way,
correlations not observed, depends on the main method of aggregation,
negative values in data, lack of risk accumulation in one category is
substituted with high risk in other.
