船舶AIS轨迹提取,作出船舶AIS轨迹图。在此基础上,实现基于空间相似距离的K均值轨迹聚类。算法可以自定义轨迹聚类初始轨迹或者由程序随机生成初始轨迹,采用迭代的方法直到确定最终的聚类中心。(The extraction of ship AIS trajectory, make ship AIS trajectories. On this basis, to achieve similar K mean trajectory clustering based on distance space. You can customize the initial trajectory trajectory clustering algorithm or randomly generated by the program initial trajectory, iterative method was used to determine the cluster center until the end. )
关于CoVaR和Copula的R代码,大部分Copula都可以通过此代码计算对应的CoVaR(You can use this package to estimate the CoVaR based on various copulas)
说明: R语言实践教程源代码,包括简单逻辑计算,和复杂图形绘制(R language practice tutorial source code, including simple logic calculation, and complex drawing)
说明: 用R语言写出的copula-GARCH函数(copula-GARCH function using R language)
说明: m-k趋势检验,做时序趋势变化的方法的源代码(M-k trend test, the source code of the method of temporal trend change)
用来做判别分析,内含案例数据和代码,适用于初学者(Used for discriminant analysis, with case data and code, for beginners)
