摘要

我们推广了多元Tweedie分布的模型校准,以允许审查的观测;估计是基于矩量法。我们考虑的多变量Tweedie分布通过一个共同的随机分量将生命池中的依赖性纳入其中。从全国范围内的群体到以雇主为基础的养老金年金组合,资金池可以有多种解释。一般来说,常见的随机成分代表了系统寿命风险,这在用于年金定价和预留的标准生命表和精算模型中没有考虑到。

A Multivariate Tweedie Lifetime Model: Censoring and Truncation
We generalize model calibration for a multivariate Tweedie distribution to allow for censored observations; estimation is based on the method of moments. The multivariate Tweedie distribution we consider incorporates dependence in a pool of lives via a common stochastic component. Pools may be interpreted in various ways, from nation-wide cohorts to employer-based pension annuity portfolios. In general, the common stochastic component is representative of systematic longevity risk, which is not accounted for in standard life tables and actuarial models used for annuity pricing and reserving.
