WebA standard (one-dimensional) Wiener process (also called Brownian mo-tion) is a continuous-time stochastic process fW tg t 0 (i.e., a family of real random variables indexed by the set of nonnegative real numbers t) with the following properties: (A) W 0 = 0. (B)With probability 1, the function t!W tis continuous in t. (C)The process fW tg WebA bivariate Wiener process model with measurement errors was used to model the degradation measurements. A two-stage method and the Markov chain Monte Carlo (MCMC) method were combined to estimate the unknown parameters in sequence. Results from a numerical example about fatigue cracks show that the proposed method is valid as

WebJan 6, 2002 · We extend the bivariate Wiener process considered by Whitmore and co-workers and model the joint process of a marker and health status. The health status process is assumed to be latent or unobservable. The time to reach the primary end point or failure (death, onset of disease, etc.) is the time when the latent health status process …
