For risk assessing, this article proposes a new method to acquire dynamically parameters varying with time, to get hazard rate of a single point, and to calculate the aggregate hazard rate.

文章分析了网上银行的风险,建立了包括风险识别、风险分析、风险模型和风险防范等多个要素组成的网上银行业务风险的评价和控制模型,针对风险评价,提出了动态获取随时间变化的参数,获得单点的危险率,计算总体的危险率的一种新方法。

First, the hazard rate of flea increased with the temperture increasing, but decreased with the relative humidity, and the temperture had more effects on the flea than the relative hu.

利用生存分析的方法 ,建立了二齿新蚤新羽化蚤在羽化后未吸血的雌蚤和雄蚤 ,羽化后吸一次血再未吸血的雌蚤和雄蚤 ,羽化后每日喂血一小时的雌蚤 ,羽化后每日喂血一小时的雄蚤四种水平下的对数线性回归模型和危险率模型 ,得到如下结论 :首先 ,危险率随着温度的增高而增大 ,随着湿度的增高而减小 ,并且温度对二齿新蚤的生存影响大于湿度 。
