How to reduce the number of rating scale items without predictability loss? [PDF]

open access: yesScientometrics, 2017
Rating scales are used to elicit data about qualitative entities (e.g., research collaboration). This study presents an innovative method for reducing the number of rating scale items without the predictability loss. The "area under the receiver operator

open access: green, 2016
The paper deals with recovering an unknown vector β ∈ R^p based on the observations Y = Xβ + ∈ξ and Z = X + σζ, where X is an unknown n×p-matrix with n ≥ p, ξ ∈ R^p is a standard white Gaussian noise, ζ is a n × p-matrix with i.i.d. standard Gaussian entries, and ∈, σ ∈ R^+ are known noise levels. It is assumed that X has a large condition number and p

Personalized decision making – A conceptual introduction

open access: yesJournal of Causal Inference, 2023
Personalized decision making targets the behavior of a specific individual, while population-based decision making concerns a subpopulation resembling that individual.

Decision-theoretic foundations for statistical causality

open access: yesJournal of Causal Inference, 2021
We develop a mathematical and interpretative foundation for the enterprise of decision-theoretic (DT) statistical causality, which is a straightforward way of representing and addressing causal questions.

Decision-theoretic foundations for statistical causality: Response to Pearl

open access: yesJournal of Causal Inference, 2022
I thank Judea Pearl for his discussion of my paper and respond to the points he raises. In particular, his attachment to unaugmented directed acyclic graphs has led to a misapprehension of my own proposals. I also discuss the possibilities for developing

Causation and decision: On Dawid’s “Decision theoretic foundation of statistical causality”

open access: yesJournal of Causal Inference, 2022
In a recent issue of this journal, Philip Dawid (2021) proposes a framework for causal inference that is based on statistical decision theory and that is, in many aspects, compatible with the familiar framework of causal graphs (e.g., Directed Acyclic ...

A unified approach for covariance matrix estimation under Stein loss [PDF]

open access: yes, 2021
In this paper, we address the problem of estimating a covariance matrix of a multivariate Gaussian distribution, relative to a Stein loss function, from a decision theoretic point of view. We investigate the case where the covariance matrix is invertible

Why scoring functions cannot assess tail properties [PDF]

open access: yes, 2019
Motivated by the growing interest in sound forecast evaluation techniques with an emphasis on distribution tails rather than average behaviour, we investigate a fundamental question arising in this context: Can statistical features of distribution tails ...
