Some Properties of an Algebraic Representation of Stochastic Processes

open access: yesThe Annals of Mathematical Statistics, 1968
Heller's (1965) concept of a stochastic module is examined with the purpose of seeing what are the algebraic implications of various probabilistic properties of discrete time, finite state processes. $k$th order Markovity, recurrence, stationarity, and ergodicity are given characterizations in terms of the stochastic module.

Some aspects of statistical causality

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Causal thinking is deeply embedded in scientific understanding of the problems of applied statistics. This can not always be done by experiments and the researcher is restricted to observing the system he wants to describe.

Numerically Representing A Stochastic Process Algebra

open access: yesCoRR, 2010
The syntactic nature and compositionality characteristic of stochastic process algebras make models to be easily understood by human beings, but not convenient for machines as well as people to directly carry out mathematical analysis and stochastic simulation.

A unified approach of catastrophic events [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2004
Although there is an accumulated charge of theoretical, computational, and numerical work, like catastrophe theory, bifurcation theory, stochastic and deterministic chaos theory, there is an important feeling that these matters do not completely cover ...

Existence of Measurable Versions of Stochastic Processes

open access: yesAxioms
Let (X,A,P), (Y,B,Q) be two arbitrary probability spaces and P:={(A,Py):y∈Y} be a regular conditional probability (rcp) on A with respect to Q. Denote by R the skew product of P and Q determined by P on the product σ-algebra A⊗B and by R^ its completion.

Splitting of Conditional Expectations and Liftings in Product Spaces II

open access: yesAxioms
Let (X,A,P) and (Y,B,Q) be two probability spaces, R be their skew product on the product σ-algebra A⊗B and {(Ay,Sy):y∈Y} be a Q-disintegration of R. Then, let A⋇B be the σ-algebra generated A⊗B and by the family M:={E⊂X×Y:∃N∈B0∀y∉NSy^(Ey)=0} and R⋇ be ...

Compositional solution of stochastic process algebra models.

open access: yes, 2002
This dissertation is about the solution of Markovian stochastic process algebra (SPA) models and the avoidance of the state-space explosion problem. We try to answer the question whether the compositionality of SPA models can be exploited to overcome the largeness problems appearing when evaluating such models.
