Let Me See: Visualizing Actuarial Information Aleksey Popelyukhin, Ph.D. Vice President, Information Systems & Technology aleksey@commrisk.com COMMERCIAL RISK Actuarial Process Data Collection, Cleanup and Transformation Application of Agorithms and Methods Representation of Results 0 Actuarial Process Algorithms Results Data 1 Ideal Actuarial System An ideal actuarial processing solution is a a) transparent to users and b) highly efficient storage/retrieval system for c) structured actuarial data (objects) with d) an extremely flexible, e) computationally complete, f) open calculation engine and g) integrated, h) automated and i) interactive report generator 2 Actuarially-Centric Systems Insurance companies build their computer systems around their strengths: Claims Accounting Underwriting Actuarial Functionality is always an afterthought 2a Human perception Relies heavily on Short-Term Memory. Problems with STM: Can hold only 5-7 similar similar items at once It’s a “buffer”: new info erases old information Even without distractions can hold info only for 30 seconds 2b Data-Driven Technologies Adaptive Reporting Visualization Alarm Systems 2c Adaptive Reporting Adaptive Reporting Filtering Sorting Outlining Conditional Formatting OLAP-enabled tools 2d Adaptive Reporting: Filtering Auto-Filter in Excel Plain-Vanilla Filtering Checking Distinct Values Adaptive Filtering (through VBA) 3 Adaptive Reporting: Outlining Outlining in Excel Hierarchical view Different level of details Subtotals Master-Detail relationship in Access 4 Adaptive Reporting: Sorting Does not reduce amount of information displayed Brings most important info on top or up front Requires definition of importance 5 Adaptive Reporting: Dynamic Formatting Conditional allows Formatting in Excel users to define font color border background pattern of a cell as a function of the values in other cells 6 Adaptive Reporting: OLAP (Online Analitycal Processing) Pivot Tables and OLAP cubes in Excel Combine Add on-the-fly processing Filtering Outlining Sorting Calculated Field Calculated Item Data Source is not limited by 65,536 rows 7 Visualization: Charts There is a chart for every occasion: line chart for displaying increases bar for shares pedestal for ranks Gantt for schedules But what about actuarial triangles? 8 Visualization: Charts 1.250 1.200 1.150 1.100 1.050 24 - 36 60 - 72 1989 1990 1991 1992 1994 1995 1996 1997 1993 1.000 96 - 108 8a Visualization: Maps Maps in Microsoft MapPoint: Colors Shapes Glyphs Isosurfaces Links to Office applications VBA 9 Visualization: Animation If a picture is worth a thousand words, then an animation is worth a thousand pictures “selective attention”: people react on any movement (change in color, shape or position) display of different stages in the motion displacement plots time animations streamlines (traces) For actuaries: iterations of simulation! 10 Visualization: Visual Tools Making actuarial selections interactively, directly on the chart Instant visual feedback Changing parameters during animation: invaluable for DFA 11 Alarm Systems: Data Quality Alarm System triggers an action whenever problem is found: creates record in the log sends e-mail stops processing runs additional tests 12 Alarm Systems: Algorithms Applicability Actuarial assumptions testing Mack Murphy Zehnwirth 13 Alarm Systems: Digital Dashboard Portal to the most important info Corporate Professional Personal Dashboard’s space limitations reemphasize the necessity of spaceconscious reporting techniques! 14 Conclusion For effective use of computerized reporting tools available to actuaries, it is imperative to define measurable indicators of actuarial significance… 15 Conclusion “The gods help them that help themselves.” Aesop 15 Me.About Actuarially related activities: • • • • Prize for the best article in the “Data Management discussion paper” call (1997). Creation and distribution of actuarial software • Triangle Maker® (1994), Triangle Maker® Pro (1997), Actuarial Toolchest™ (1998) , Enabler™ (1999) Design, development and coding of the 2nd and 3rd (current) generation of Affinity (1996) Promotion of notions like Ideal Actuarial System and Data Quality Shield, and paradigms like object-oriented actuarial software and data-driven visualization. Presently developing an integrated pricing/reserving/DFA computer system for reinsurance and also an action/adventure computer game tentatively called “Actuarial Judgement”.
