RISK MANAGEMENT WITH DATA VISULISATION
MORTGAGE LOANS DEFAULT CHART OF TURKEY
RISK REPORT (abridged)
Description of The Report
This a abridged Sample Report of Defaulted Mortgage Loans for the 12 NUTS Sectors and 81 cities of Turkey
with 2012-2014 time spanCovers only Whole Turkey and West
Anatolia RegionReal Report covers all the 12 NUTS
Regions and 81 Cities of TurkeyWith 2010-2015 time span
Purpose of the Report• With this study we investigate NUTS 12
Regions credit loans performations by Graphical Datamining Analysis technique with a suitable software developed by us.
• This technique is submitted various OR and Finance congress
• Dataset are factorized according to cities and years, sectorals and financial periods factors.
• Sample Report Covers Periods: 2012-2014 accounts.
Source of The Data• We downloaded FINTURK dataset from
the site of BRSA and anotated it by NUTS factors.
• Our software read this data from an excel file with the name of “dataset”
• From now on “dataset” means our improvised NUTS Credit Loans FINTURK data
Description of The Analytics• Data: BRSA* and NUTS of Turkey
(Nomenclature of Territorial Units for Statistics, NUTS)• Dataset: NUTS Region Investment Promotion
and 3 account period Graphical Datamining Analysis of FINTURK of BRSA
• Period: 2012-2014 Accounts• Dataset are factorized according to year, sector,
quarter and region factors. • Graphical Datamining and Data Visualisation
applied on this factorized data.

Graphical DataMining Analysis with FINTURK Sectoral Loans Dataset
• Real Time Interactive Data Management for
• Effect and Response Analysis
Technique: • Graphical DataMining using #ggplot2
Graphical Package of #R Software• Graphical DataMining will be the
dominant anlysis technique of the future
Styles of Graphs• For brevity we apply three types off
ggplot2 graphical styles with ggplot2 geoms with this report1. Densityplot with geom_density()2. Violinplot with
geom_violin()3. Facetplot with facet_grid()
• Logarithmic scale leads a more stable density formations for financial data.
Description of Density Graphs• Density Graphs are the
continuous version of Histograms They plot a single numerical variable against their frequency.
• We can detect single or multiple peaks of density graphs and pinpoint the effective factors.
• On the other hand soperposing density graphs acording the factors with different colors provide us with information of the effect of the factors
Description of Violin Graphs• Violin Graphs can be
seen as two-dimensional density graphs
• Axis of the violin represents the median of the free variable
• Through the median of X-axis Y-density graph occurs with mirror copy
Mushroom, Pottery and Bottle Risk Profiles• Violin Graphs comes
with Mushroom, Pottery and Bottle formations
• Mushroom formation represents a risk concentration on hig order values of financial data
• Pottery means risk on the medium order
• and the bottle menas risk on the lower orders
Description of Power Law Graphs
• When double Log scale applied Power Law analysis is a by product
• LogY = a.LogX + b• a is the Risk
Measure • And it is the same
for every level of X and Y
• Power Law means that risk is scale free
Description of Facet Graphs• Facet graphs of
ggplot2 package can show us
3-dimensional graphs distributed according 3 factors in matrix form.
• In which we can see the anomalies occurs on which year and which region and which period.
Risk ProfilesGraphical Dataminig of the Profiles
of Default Mortgage Risks for Whole Turkey, 12 NUTS Regions
and 81 Cities(This version covers only Whole Turkey
and West Anatolia Region)
Risk Profiles for Whole Turkey

Conclusion• Graphical Datamining applied on this
factorized data and financial anomalies detected acording to time and space factors.
• We observes apparently obvious differences of risk profiles affected by these factors
• It is quite clear that pictures tells more stories than numbers
• This is only an abridged version of the whole report for 12 Nuts Regions
