Stochastic models in phylogenetic comparative methods: analytical properties and parameter estimation
Krzysztof Bartoszek
Phylogenetic comparative methods are well established tools for using inter-species variation to analyse phenotypic evolution and adaptation. They are generally hampered, however,…
Multivariate Aspects of Phylogenetic Comparative Methods
Krzysztof Bartoszek
This thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of c…
"Old Techniques for New Times": the RMaCzek package for producing Czekanowski's Diagrams
Krzysztof Bartoszek, Albin Västerlund
Inspired by the MaCzek Visual Basic program we provide an R package, RMaCzek, that produces Czekanowski's diagram. Our package permits any seriation and distance method the user pr…
Are official confirmed cases and fatalities counts good enough to study the COVID-19 pandemic dynamics? A critical assessment through the case of Italy
Krzysztof Bartoszek, Emanuele Guidotti, Stefano Maria Iacus +1
As the COVID-19 outbreak is developing the two most frequently reported statistics seem to be the raw confirmed case and case fatalities counts. Focusing on Italy, one of the harde…
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…
Simulating an infinite mean waiting time
Krzysztof Bartoszek
We consider a hybrid method to simulate the return time to the initial state in a critical-case birth--death process. The expected value of this return time is infinite, but its di…
