比较生存曲线可以用统计假设测试日志秩检验。它是用来测试的零假设，没有任何区别的人口的生存曲线（即概率事件发生在任何时间点是相同的每个人口）.这个函数使用卡普兰曲线的程序来估计生存函数.(Comparison of two survival curves can be done using a statistical hypothesis test called the log rank test. It is used to test the null hypothesis that there is no difference between the population survival curves (i.e. the probability of an event occurring at any time point is the same for each population). This function use the Kaplan-Meier procedure to estimate the survival function, so it is mandatory to download )

这是关于微分方程求解的资料，我自己看了好几遍，很经典，并且也很全面，并附有例子(This is a differential equation solver, I have read it several times, very classic, and also very comprehensive, with examples)

根据观测值与状态量，利用卡尔曼滤波算法对未来状态变量进行状态估计(According to the observation and state variables, Calman filter algorithm is used to estimate the state variables in the future.)
