A recently proposed nearest neighbor based selection of time delays for phase space reconstruction is extended to multivariate time series, with an iterative selection of variables and time delays. A case study of numerically generated solutions of the x- and z coordinates of the Lorenz system, and an application to heart rate and respiration data, are used for illustration.
最近提出的基于最近邻的相空间重构时间延迟选择方法被扩展到多变量时间序列，采用变量和时间延迟的迭代选择。通过对洛伦兹系统x坐标和z坐标的数值生成解进行案例研究，并将其应用于心率和呼吸数据来说明这一方法。
