摘要 在Lee-Carter随机死亡率假定下,建立利率分别为ARMA(p,q)模型和Cox-Ingerson&Ross模型(简称CIR模型)的生存年金组合模型。推导出生存年金组合的精算现值。 Based on Lee-Carter mortality model,we establish a life annuity combination model in which there exist two kinds of independent stochastic interest rates model,namely,the rate satisfying ARMA(p,q) model and the rate satisfying Cox-Ingerson-Ross model.Finally,we derive the actuarial present value expression of the life annuity combination model.
