Unpaired multi-domain causal representation learning

N Sturma, C Squires, M Drton… - Advances in Neural …, 2024 - proceedings.neurips.cc
The goal of causal representation learning is to find a representation of data that consists of
causally related latent variables. We consider a setup where one has access to data from …

Identification based on higher moments

DJ Lewis - 2024 - econstor.eu
Identification based on higher moments has drawn increasing theoretical attention and been
widely adopted in empirical practice in macroeconometrics in the last two decades. This …

[PDF][PDF] Uncertain Short-Run Restrictions and Statistically Identified Structural Vector Autoregressions

SA Keweloh - arXiv preprint arXiv:2303.13281, 2024 - researchgate.net
This study proposes a combination of a statistical identification approach with potentially
invalid short-run zero restrictions. The estimator shrinks towards imposed restrictions and …

Structural Vector Autoregressions and Higher Moments: Challenges and Solutions in Small Samples

SA Keweloh - arXiv preprint arXiv:2310.08173, 2023 - arxiv.org
Generalized method of moments estimators based on higher-order moment conditions
derived from independent shocks can be used to identify and estimate the simultaneous …

Cumulant Tensors in Partitioned Independent Component Analysis

M Garrote-López, M Stephenson - arXiv preprint arXiv:2402.10089, 2024 - arxiv.org
In this work, we explore Partitioned Independent Component Analysis (PICA), an extension
of the well-established Independent Component Analysis (ICA) framework. Traditionally, ICA …

[HTML][HTML] Identification of vector autoregressive models with nonlinear contemporaneous structure

F Cordoni, N Dorémus, A Moneta - Journal of Economic Dynamics and …, 2024 - Elsevier
We propose a statistical identification procedure for recursive structural vector
autoregressive (VAR) models that present a nonlinear dependence (at least) at the …

Parameter identification in linear non-Gaussian causal models under general confounding

D Tramontano, M Drton, J Etesami - arXiv preprint arXiv:2405.20856, 2024 - arxiv.org
Linear non-Gaussian causal models postulate that each random variable is a linear function
of parent variables and non-Gaussian exogenous error terms. We study identification of the …

Tensors in algebraic statistics

M Casanellas, L Sierra, P Zwiernik - arXiv preprint arXiv:2411.14080, 2024 - arxiv.org
Tensors are ubiquitous in statistics and data analysis. The central object that links data
science to tensor theory and algebra is that of a model with latent variables. We provide an …

Identification of Independent Shocks Under (Co-) heteroskedasticity

H Herwartz, S Wang - Available at SSRN 4577627, 2023 - papers.ssrn.com
Recent development in identification methods utilizing higher-order moments have
advanced structural analysis in macroeconomics. This paper reviews prevailing …

Identification of one independent shock in structural VARs

G Fiorentini, A Moneta, F Papagni - 2024 - econstor.eu
We establish the identification of a specific shock in a structural vector autoregressive model
under the assumption that this shock is independent of the other shocks in the system …
