Fluctuation Theory of Recurrent Events

A Continuous Time Analogue of the Theory of Recurrent Events

and thus much of the interest in the theory of recurrent events is centered on the "renewal sequence" {un} . Let us write (R for the class of all renewal sequences. Because the word "recurrent" has come to be used in a different sense in Markov chain theory, we shall avoid it, and use instead the term "regenerative" to describe the events to be considered here. Then the form of the definition (...

Dynamic Frailty and Change Point Models for Recurrent Events Data

Abstract. We present a Bayesian analysis for recurrent events data using a nonhomogeneous mixed Poisson point process with a dynamic subject-specific frailty function and a dynamic baseline intensity func- tion. The dynamic subject-specific frailty employs a dynamic piecewise constant function with a known pre-specified grid and the baseline in- tensity uses an unknown grid for the piecewise ...

Fluctuation Theory of Random Copolymers

We investigate trie behavior of symmetric AB random copolymer melt near trie point of microphase separation in trie framework of a one-trop (Hartree-Fock) approximation, that exactly salves trie problem. We bave shown that composition fluctuations result to complete elimination of trie microphase separation predicted in trie frarnework a mean-field approximation [1-5]. Using variational techniq...

Time to Recurrent Relapses Analysis in Schizophrenic Patients by Using Recurrent Events Model

Objective: Schizophrenia is to be emphasized due to its high prevalence, severity of symptoms and frequent recurrences. In this study the hazard of recurrence of Schizophrenia was analyzed by using recurrent events models. Materials & Methods: This study was an observational prospective study. Data was gathered from 159 registered schizophrenia patients at Razi Psychiatric Center. The type I...
