These concepts are illustrated with samples of time-varying probability distributions for human mortality, time-varying covariance matrices derived from trading patterns and time-varying networks that arise from New York taxi trips. We establish asymptotic consistency of the sample-based estimators for the corresponding population targets under mild metric entropy conditions on О© and continuity of the О©-valued random curves. Using the notion of generalized FrГ©chet integrals, we construct object functional principal components that lie in the metric space О©. Frchet mean and variance provide a way of obtaining a mean and variance for metric space-valued random variables, and can be used for statistical. Analogues of functional principal components for time-varying objects are obtained by applying FrГ©chet means and projections of distance functions of the random object trajectories in the directions of the eigenfunctions, leading to real-valued FrГ©chet scores. Then the eigenfunctions of the linear operator with the autocovariance function as kernel can be used as building blocks for an object functional principal component analysis for О©-valued functional data, including time-varying probability distributions, covariance matrices and time dynamic networks.

The proposed metric autocovariance function is non-negative definite when the squared semimetric d 2 is of negative type. This is an online quiz called 10 Random Objects.

We propose metric covariance, a novel association measure for paired object data lying in a metric space (О©, d) that we use to define a metric autocovariance function for a sample of random О©-valued curves, where О© generally will not have a vector space or manifold structure. These data can be viewed as elements of a general metric space that lacks local or global linear structure and therefore common approaches that have been used with great success for the analysis of functional data, such as functional principal component analysis, cannot be applied. In recent years, samples of time-varying object data such as time-varying networks that are not in a vector space have been increasingly collected. Functional data analysis provides a popular toolbox of functional models for the analysis of samples of random functions that are real valued.
