Survival analysis following dynamic randomization
In this paper, we propose a method to analyze survival data from a clinical trial that utilizes a dynamic randomization for subject enrollment. The method directly accounts for dynamic subject randomization process using a marked point process (MPP). Its

Chaos representations for marked point processes
We show that for a large class of marked point processes there exists a random measure m with the predictable representation property such that iterated integrals with respect to m span the space of square integrable random variables.

Bond markets where prices are driven by a general marked point process [PDF]
We investigate the term structure for the case when interest rates are allowed to be driven by a general marked point process as well as by a Wiener process.

We consider spatially homogeneous marked point patterns in an unboundedly expanding convex sampling window. Our main objective is to identify the distribution of the typical mark by constructing an asymptotic $\chi^2$-goodness-of-fit test.

Agglomeration Economies in Ukrainian Dairy Sector: a Marked Point Process Approach [PDF]
Even after more than 15 years of transition from plan to market, agriculture in Ukraine still faces many challenges in terms of its structure. The evidence in the literature points to significant heterogeneity of technical efficiency and productivity ...

Influence of information on behavioral effects in decision processes
Rational models in decision processes are marked out by many anomalies, caused by behavioral issues. We point out the importance of information in causing inconsistent preferences in a decision process.

Detecting Dependence Between Marks and Locations of Marked Point Processes
SummaryWe introduce two characteristics for stationary and isotropic marked point proces- ses, E(h) and V(h), and describe their use in investigating mark–point interactions. These quantities are functions of the interpoint distance h and denote the conditional expectation and the conditional variance of a mark respectively, given that there is a ...

Log-Gaussian Cox processes are an important class of models for spatial and spatiotemporal point-pattern data. Delivering robust Bayesian inference for this class of models presents a substantial challenge, since Markov chain Monte Carlo (MCMC ...

The Fight of Ukraine for the Autocephal Church in the context of politicization of Religion
The article analyzes the process of the movement of the Ukrainian authorities and certain church circles for receiving Tomos (ecclesiastical permission) for the creation of a single Ukrainian Orthodox Church, which has now unfolded. The authors point out

Universal dynamics on the way to thermalization
It is demonstrated how a many-body system far from thermal equilibrium can exhibit universal dynamics in passing a nonthermal fixed point. As an example, the process of Bose–Einstein (BE) condensation of a dilute cold gas is considered.
