Executive stock option exercise with full and partial information on a drift change point [PDF]

open access: yes, 2020
We analyse the optimal exercise of an executive stock option (ESO) written on a stock whose drift parameter falls to a lower value at a change point, an exponentially distributed random time independent of the Brownian motion driving the stock.

m-Consecutive-k-out-of-n: F Structures with a Single Change Point

open access: yesMathematics, 2020
In the present article, we introduce the m-consecutive-k-out-of-n:F structures with a single change point. The aforementioned system consists of n independent components, of which the first n1 units are identically distributed with common reliability p1,

Univariate Mean Change Point Detection: Penalization, CUSUM and Optimality [PDF]

open access: yes, 2018
The problem of univariate mean change point detection and localization based on a sequence of $n$ independent observations with piecewise constant means has been intensively studied for more than half century, and serves as a blueprint for change point ...

Changing Pattern of Water Level Trends in Eurasian Endorheic Lakes as a Response to the Recent Climate Variability

open access: yesRemote Sensing, 2021
Lake level is a sensitive integral indicator of climate change on regional scales, especially in enclosed endorheic basins. Eurasia contains the largest endorheic zone with several large terminal lakes, whose water levels recently underwent remarkable ...

Does Biochar Addition Influence the Change Points of Soil Phosphorus Leaching?

open access: yesJournal of Integrative Agriculture, 2014
Phosphorus change point indicating the threshold related to P leaching, largely depends on soil properties. Increasing data have shown that biochar addition can improve soil retention capacity of ions.

Sequential subspace change point detection [PDF]

open access: yesSequential Analysis, 2020
We consider the online monitoring of multivariate streaming data for changes that are characterized by an unknown subspace structure manifested in the covariance matrix. In particular, we consider the covariance structure changes from an identity matrix to an unknown spiked covariance model.

Dirichlet Process Hidden Markov Multiple Change-point Model [PDF]

open access: yes, 2014
This paper proposes a new Bayesian multiple change-point model which is based on the hidden Markov approach. The Dirichlet process hidden Markov model does not require the specification of the number of change-points a priori.
