A mixed relaxed clock model
Over recent years, several alternative relaxed clock models have been proposed in the context of Bayesian dating. These models fall in two distinct categories: uncorrelated and autocorrelated across branches. The choice between these two classes of relaxed clocks is still an open question. More fundamentally, the true process of rate variation may have both long-term trends and short-term fluct...
متن کاملRelaxed Clock Di erence Diagrams for Timed Automata Model Checking
Clock Di erence Diagrams (CDDs), a BDD-like data structure for model checking of timed automata, were presented in 1999. After the original article the work on them seems to have stopped, although there are still important open questions. The proposed algorithm relied on the traditionally used data structure (DBMs) for most operations. CDDs de nition required that repeated subtrees were aliased...
متن کاملA general comparison of relaxed molecular clock models.
Several models have been proposed to relax the molecular clock in order to estimate divergence times. However, it is unclear which model has the best fit to real data and should therefore be used to perform molecular dating. In particular, we do not know whether rate autocorrelation should be considered or which prior on divergence times should be used. In this work, we propose a general bench ...
متن کاملBayesian dating of shallow phylogenies with a relaxed clock.
Bayesian methods are increasingly being used to estimate divergence times without the restrictive assumption of a global clock. Little is known about their reliability for shallow phylogenies where DNA sequence divergence is low. We analyzed both simulated and real sequences to evaluate dating methods in phylogenies with mid-late Miocene roots. A large number of data sets (5000) with 10 taxa ea...
متن کاملGeneralized Equilibrium Problem with Mixed Relaxed Monotonicity
We extend the concept of relaxed α-monotonicity to mixed relaxed α-β-monotonicity. The concept of mixed relaxed α-β-monotonicity is more general than many existing concepts of monotonicities. Finally, we apply this concept and well known KKM-theory to obtain the solution of generalized equilibrium problem.
