Fréchet mean - Wikipedia

WebWe describe the use of the Frechet mean and variance in the Billera-Holmes-Vogtmann (BHV) treespace to summarize and explore the diversity of a set of phylogenetic trees. We show that the Frechet mean is comparable to other summary methods, and, despite its stickiness property, is more likely to be binary than the majority-rules consensus tree. WebJul 25, 2024 · Given a real random variable, its expectation and its moments are basic characteristics used in probability theory. Since we are interested in random variables (and random sets) of an arbitrary metric space (M, d), we need to consider analogous parameters.Given a random variable X of a metric space (M, d), the function \(p \mapsto … WebSep 1, 2024 · Mean and variance are two important descriptive statistics of random variables. Yet their definitions are not applicable to random objects in metric spaces. The concepts of mean and variance were generalized to random objects by defining the Fréchet mean and Fréchet variance of a random object Y as ω ⊕ = arg min ω ∈ Ω E ( d 2 ( Y , ω ... hornby x7049
