Chapter Three investigates the ruin probability of a discrete time risk model under constant interest rate with heavy tails.
第三章讨论常利率下一类大额索赔离散风险模型的破产概率估计。
In Chapter 4 we further extend the result to the case of infinite time ruin probability with heavy tails.
在第四章,我们进一步把上一章的结果推广到无限时间破产概率的场合。
Badgers have heavy bodies, thick skin, short legs, and short tails.
獾的身体笨重,皮肤很厚,脚短尾短。
Powerful hind limbs and a large heavy tail serve for balance and support. But tree kangaroos have shorter prehensile tails and climb rather than hop.
