Change of measure up to a random time: theory

Journal of Applied Probability, 1991
Change of measure up to fixed times or stopping times is the theme of the famous Cameron–Martin–Girsanov formula. The paper studies change of measure up to random times which are not stopping times of the natural filtration. The ultimate aim is to build up a family of interesting models for physics and chemistry.

Random Time-Changed Extremal Processes

Theory of Probability & Its Applications, 2007
The point process N = {(Tk ,X k ): k ≥ 1} we deal with here is an assumed Bernoulli point process with independent random vectors Xk in (0, ∞)d and with random time points Tk in (0, ∞), independent of X. For normalizing we use a regular sequence ξn(t, x )=( τn(t) ,u n(x)) of time-space changes of (0, ∞) 1+d .

Quickest detection of an abrupt change in a random sequence with finite change-time

IEEE Transactions on Information Theory, 1994
Summary: This paper proposes a new procedure for quickest detection of an abrupt change in a random sequence, where a change is known to occur with probability one. Applications include on-line speech segmentation, edge detection in image processing, and communications channel monitoring. In contrast to \textit{A. N.
