On the Convergence Rate of the Quasi- to Stationary Distribution for the Shiryaev-Roberts Diffusion

Kexuan Li, Aleksey S. Polunchenko

For the classical Shiryaev--Roberts martingale diffusion considered on the interval , where is a given absorbing boundary, it is shown that the rate of convergence of…

Analytic Evaluation of the Fractional Moments for the Quasi-Stationary Distribution of the Shiryaev Martingale on an Interval

Kexuan Li, Aleksey S. Polunchenko, Andrey Pepelyshev

We consider the quasi-stationary distribution of the classical Shiryaev diffusion restricted to the interval with absorption at a fixed . We derive analytically a clos…

Analytic moment and Laplace transform formulae for the quasi-stationary distribution of the Shiryaev diffusion on an interval

Aleksey S. Polunchenko, Andrey Pepelyshev

We derive analytic closed-form moment and Laplace transform formulae for the quasi-stationary distribution of the classical Shiryaev diffusion restricted to the interval wi…

A Note on the Quasi-Stationary Distribution of the Shiryaev Martingale on the Positive Half-Line

Aleksey S. Polunchenko, Servet Martinez, Jaime San Martin

We obtain a closed-form formula for the quasi-stationary distribution of the classical Shiryaev martingale diffusion considered on the positive half-line with f…

Comparative Performance Analysis of the Cumulative Sum Chart and the Shiryaev-Roberts Procedure for Detecting Changes in Autocorrelated Data

Aleksey S. Polunchenko, Vasanthan Raghavan

We consider the problem of quickest change-point detection where the observations form a first-order autoregressive (AR) process driven by temporally independent standard Gaussian…

Asymptotic Exponentiality of the First Exit Time of the Shiryaev-Roberts Diffusion with Constant Positive Drift

Aleksey S. Polunchenko

We consider the first exit time of a Shiryaev-Roberts diffusion with constant positive drift from the interval where . We show that the moment generating function (Lap…
