Statistical models with uncertain error parameters

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
In a statistical analysis in Particle Physics, nuisance parameters can be introduced to take into account various types of systematic uncertainties. The best estimate of such a parameter is often modeled as a Gaussian distributed variable with a given ...

GDP Forecasting: Machine Learning, Linear or Autoregression?

open access: yesFrontiers in Artificial Intelligence, 2021
This paper compares the predictive power of different models to forecast the real U.S. GDP. Using quarterly data from 1976 to 2020, we find that the machine learning K-Nearest Neighbour (KNN) model captures the self-predictive ability of the U.S. GDP and

Statistical models of fracture [PDF]

open access: yesAdvances in Physics, 2006
Disorder and long-range interactions are two of the key components that make material failure an interesting playfield for the application of statistical mechanics. The cornerstone in this respect has been lattice models of the fracture in which a network of elastic beams, bonds or electrical fuses with random failure thresholds are subject to an ...

Mapping clinical outcomes to generic preference-based outcome measures: development and comparison of methods

open access: yesHealth Technology Assessment, 2020
Background: Cost-effectiveness analysis using quality-adjusted life-years as the measure of health benefit is commonly used to aid decision-makers. Clinical studies often do not include preference-based measures that allow the calculation of quality ...

Fisher’s significance test: A gentle introduction

open access: yesGMS Medizinische Informatik, Biometrie und Epidemiologie, 2020
The p-value is often misunderstood and, for example, misinterpreted as a probability for the correctness of the null hypothesis. The aim of this article is to first explain the definition of the p-value.
