Normal approximation for mixtures of normal distributions and the evolution of phenotypic traits
Krzysztof Bartoszek, Torkel Erhardsson
An explicit bound is given for the Kolmogorov distance between a mixture of normal distributions and a normal distribution with properly chosen parameter values. A random variable…
PSICA: decision trees for probabilistic subgroup identification with categorical treatments
Oleg Sysoev, Krzysztof Bartoszek, Eva-Charlotte Ekstrom +1
Personalized medicine aims at identifying best treatments for a patient with given characteristics. It has been shown in the literature that these methods can lead to great improve…
Trait evolution with jumps: illusionary normality
Krzysztof Bartoszek
Phylogenetic comparative methods for real-valued traits usually make use of stochastic process whose trajectories are continuous. This is despite biological intuition that evolutio…
Time to a single hybridization event in a group of species with unknown ancestral history
Krzysztof Bartoszek, Graham Jones, Bengt Oxelman +1
We consider a stochastic process for the generation of species which combines a Yule process with a simple model for hybridization between pairs of co-existent species. We assume t…
