Multivariate representations of univariate marked Hawkes processes

open access: yesScandinavian Journal of Statistics, EarlyView.
Abstract Univariate marked Hawkes processes are used to model a range of real‐world phenomena including earthquake aftershock sequences, contagious disease spread, content diffusion on social media platforms, and order book dynamics. This paper illustrates a fundamental connection between univariate marked Hawkes processes and multivariate Hawkes ...

Spatial depth for data in metric spaces

open access: yesScandinavian Journal of Statistics, EarlyView.
Abstract We propose a novel measure of statistical depth, the metric spatial depth, for data residing in an arbitrary metric space. The measure assigns high (low) values for points located near (far away from) the bulk of the data distribution, allowing quantifying their centrality/outlyingness.

Image of mathematics: A case study of two women's early mathematics experiences

open access: yesSchool Science and Mathematics, EarlyView.
Abstract People often view mathematics as abstract, cold, and irrelevant to real life, and their school experiences likely influence such views. In this case study, we investigated the mathematics experiences of two women who participated in an afterschool girls‐only STEM club 30 years ago when they were in fifth and sixth grades.

Function Art: Linking Mathematics, Technology, and Visual Arts

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT This study investigated students' understanding of mathematical functions and strategies to create artwork using GeoGebra. It was framed by the principles of constructionism and examined how students use functions in creating artworks. We gathered data from students' artworks using the Algebra view and the Construction Protocol in the GeoGebra

Secondary School Mathematics Teachers' Accuracy at Predicting Student Errors

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT We studied changes over time in secondary school mathematics teachers' accuracy in predicting students' errors. In a total of 37 sessions, seven teachers were asked to predict the percentage of students choosing each option in five multiple‐choice diagnostic questions taken from the free website https://diagnosticquestions.com/.
