Copula Estimation of Distribution Algorithm Sampling from Clayton Copula

Estimation of Distribution Algorithms (EDAs) are implemented mainly by the three steps: selecting the promising subset from the current population, modeling the distribution of the selected population and sampling from the estimated model. Modeling and sampling are key steps of EDAs. They are also research topic of copula theory to represent the multivariate joint distribution by a copula and t...

Large-network travel time distribution estimation for ambulances

We propose a regression approach for estimating the distribution of ambulance travel times between any two locations in a road network. Our method uses ambulance location data that can be sparse in both time and network coverage, such as Global Positioning System data. Estimates depend on the path traveled and on explanatory variables such as the time of day and day of week. By modeling at the ...

Markov Chain Procedure for Arterial Route Travel Time Distribution Estimation

Recent advances in the GPS technology and the probe vehicles deployment offer an innovative prospect for arterial travel time research. Specifically, we focus on estimation of arterial route travel time distribution which contains more information in regard to traffic network performance measurement. In the proposed technique, probe vehicles provide travel time of the traversing links. For each...

Estimation of copula-based semiparametric time series models

This paper studies the estimation of a class of copula-based semiparametric stationary Markov models. These models are characterized by nonparametric marginal distributions and parametric copula functions, while the copulas capture all the scale-free temporal dependence of the processes. Simple estimators of the marginal distribution and the copula parameter are provided, and their asymptotic p...
