Two-resolution state modelling of intermittent online gambling activity during Sweden's temporary deposit-cap period
Sam Andersson, Timo Koski, Helga Westerlind +3
Intermittent online gambling records create two distinct representation problems: calendar-time analyses must retain represented days with no recorded play, whereas analyses of act…
Likelihood-free Model Choice for Simulator-based Models with the Jensen--Shannon Divergence
Jukka Corander, Ulpu Remes, Timo Koski
Choice of appropriate structure and parametric dimension of a model in the light of data has a rich history in statistical research, where the first seminal approaches were develop…
Nonparametric likelihood-free inference with Jensen-Shannon divergence for simulator-based models with categorical output
Jukka Corander, Ulpu Remes, Ida Holopainen +1
Likelihood-free inference for simulator-based statistical models has recently attracted a surge of interest, both in the machine learning and statistics communities. The primary fo…
Exact simulation of coupled Wright-Fisher diffusions
Celia García-Pareja, Henrik Hult, Timo Koski
In this paper an exact rejection algorithm for simulating paths of the coupled Wright-Fisher diffusion is introduced. The coupled Wright-Fisher diffusion is a family of multidimens…
A dual process for the coupled Wright-Fisher diffusion
Martina Favero, Henrik Hult, Timo Koski
The coupled Wright-Fisher diffusion is a multi-dimensional Wright-Fisher diffusion for multi-locus and multi-allelic genetic frequencies, expressed as the strong solution to a syst…
On a Multilocus Wright-Fisher Model with Mutation and a Svirezhev-Shahshahani Gradient-like Selection Dynamics
Erik Aurell, Magnus Ekeberg, Timo Koski
In this paper we introduce a multilocus diffusion model of a population of haploid, asexually reproducing individuals. The model includes parent-dependent mutation and interloc…
