On Metric Choice in Dimension Reduction for Fréchet Regression

open access: yesInternational Statistical Review, EarlyView.
Summary Fréchet regression is becoming a mainstay in modern data analysis for analysing non‐traditional data types belonging to general metric spaces. This novel regression method is especially useful in the analysis of complex health data such as continuous monitoring and imaging data.

A Stochastic Tree for Bubble Asset Modelling and Pricing

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We introduce a new stochastic tree representation of a strictly stationary submartingale process for modelling, forecasting, and pricing speculative bubbles on commodity and cryptocurrency markets. The model is compared to other trees proposed in the literature on bubble asset modelling and stochastic volatility approximation. We show that the

Change Point Analysis for Functional Data Using Empirical Characteristic Functionals

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We develop a new method to detect change points in the distribution of functional data based on integrated CUSUM processes of empirical characteristic functionals. Asymptotic results are presented under conditions allowing for low‐order moments and serial dependence in the data establishing the limiting null‐distribution of the proposed test ...

Endogenous Tax Compliance and Macroeconomic Performance Driven by Satisficing Evolutionary Dynamics

open access: yesMetroeconomica, EarlyView.
ABSTRACT We incorporate tax evasion to a demand‐led macrodynamic model of capacity utilization and output growth rate. The frequency of tax evaders is endogenously time‐varying, driven by imitation‐augmented satisficing evolutionary dynamics involving pecuniary factors, as well as non‐pecuniary elements which are reflected in the distribution of tax ...
