This paper is a note on the use of Bayesian nonparametric mixture models for continuous time series. We identify a key requirement for such models, and then establish that there is a single type of mo...

We study properties and parameter estimation of finite-state homogeneous continuous-time bivariate Markov chains.
A martingale approach to continuous time marginal structural models
martingale approach continuous time marginal structural models
2010/3/17
Marginal structural models were introduced in order to provide
estimates of causal effects from interventions based on observational studies
in epidemiological research. We present a variant of the ...
Parameter Estimation in Continuous Time Markov Switching Models: A Semi-Continuous Markov Chain Monte Carlo Approach
Bayesian inference data augmentation hidden Markov model
2009/9/24
In this paper,we combine useful aspects of both approaches.On the one hand,we are inspired by the discretization, where filtering for the state process is possible,on the other hand,we
catch attracti...

On the Novikov-Shiryaev Optimal Stopping Problems in Continuous Time
Levy processes optimal stopping problem Appell polynomials pasting principles
2009/4/24
Novikov and Shiryaev (2004) give explicit solutions to a class of optimal stopping problems for random walks based on other similar examples given in Darling et al. (1972). We give the analogue of the...
On the Goodness-of-Fit Tests for Some Continuous Time Processes
Hypotheses testing diffusion process Poisson process selfexcitingprocess goodness-of-fit tests
2010/3/19
We present a review of several results concerning the construction
of the Cram´er-von Mises and Kolmogorov-Smirnov type goodnessof-
fit tests for continuous time processes. As the models we ta...
