Eecient Modeling of Massive Longitudinal Data Using Transition Arrays


We propose a fast, inexpensive technique for summarizing and modeling massive, multidimensional, longitudinal data sets using specialized summaries called transition arrays. We do this in three steps. 1. First, characterize the data points at time t by their relative position in the data space, called a state, using a DataSphere partitioning proposed in our… (More)
