2.5.8 update

  • Integration with version 1.4 of the Projections Toolkit
  • Addition of TAS-R, TAS-D, TAS-M information into PDF model reports
  • Improvements to the file filter to find files and models by numeric ID and descriptive terms.
  • Re-classification of optional modelling fields to make variables easier fo find
  • Ability to use projections on shared files within run-off simulations
2.5.6 update
  • Integration with version 1.3 of the Projections Toolkit
  • Enhanced support for different Excel versions in Excel download formats
  • Simulation parallelisation supported on dedicated server
2.5.5 update
  • Powerful new optimisation features: automatic selection of mortality model to use, and backwards elimination to find the most parsimonious model.
  • Excel-formatted downloads of standard CSV files augmented with additional commentary and analysis.
  • Ability to base models around a standard table, in both survival-model and qx form.
  • Run-off simulation now includes your choice of valuation bases, added percentile analysis and optional use of Toolkit-generated sample paths.
  • Four new survival models: Gamma, Generalised Gamma, Normal and Logistic.
  • Individual-level residuals generation.
2.5.3 update
  • A cyclic seasonal option for CalendarPeriod, and CalendarPeriod analysis down to the monthly level
  • The ability to add optimisation user-definition rules to AgeRange and CalendarPeriod discretisation
  • Increased accuracy for discretisation due to replacing real value approximations with calendar arithmetic
  • Support for user-profile addresses in Bermuda
2.5.2 update
  • Extended standard table support, including bespoke standard table upload and validation based availability of data
  • Extensive integration with the Projections Toolkit including model sub-group piggybacking and in-force simulation
  • Extensive informational hyperlinks added to PDF output reports
2.5.1 update
  • New bias reporting and commencement date validation against uploaded data
2.5.0 Base release
  • New survival model laws: Inverse Gaussian, Log-logistic and Pareto.
  • A parameter explorer providing specific commentary and analysis of parameter estimates.
  • For ICA/Solvency II - Run-off simulations of in-force data against a selection of built-in stochastic projection bases.
  • A profile explorer allowing online interrogation of geodemographic groups/types for any licensed profiler.
  • The ability to output contingency tables to the online model browser and PDF report.
  • Greatly extended support for user-defined codes. Now as many as 30 bespoke risk factors can be uploaded and included in models.

Longevitas is used by insurers, investment banks, reinsurers and consulting actuaries to analyse demographic risks. Applications to-date include mortality, longevity, critical illness and persistency.
