This requires knowledge of two parameters: The delay parameter $\tau$, and the embedding dimension parameter $D$. Two standard methods to estimate these parameters in one-dimensional time-series involve the inspection of the Average Mutual Information (AMI) function and the False Nearest Neighbor (FNN) function. In some contexts, however, such as phase-space reconstruction for Multidimensional Recurrence Quantification Analysis (MdRQA), the empirical time series that need to be embedded already possess a dimensionality higher than one. In the current article, we present extensions of the AMI and FNN functions for higher dimensional time-series and their application to data from the Lorenz system coded in Matlab.
