Version 2.5.5 of Longevitas

Date: Apr 30, 2010

Longevitas Ltd is pleased to announce the production release of v2.5.5 of its risk-modelling software

Since the 2.5 base release the software incorporates additional functionality to enhance your productivity, including:

  • 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.
  • 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
  • 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
  • New bias reporting and commencement date validation against uploaded data
  • 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.
