Testing the normality assumption in an ordered probit model using an artificial regression : some results for the LM-test

Wilde, Joachim; Forstinger, Sarah - 2026

The key assumption of normally distributed error terms is usually not tested in empirical practice when using ordered probit models. Therefore, an artificial regression version of the LM test against the class of Pearson distributions is derived that can be implemented more easily than the...

Fine-Scale Spatial Disaggregation of Statistical Data via Graph Neural Networks

Lee, Kamwoo; Blankespoor, Brian; Newhouse, David - 2026

Fine-grained spatial data are critical for informed decision-making in domains ranging from economic planning to environmental management. However, many statistics are only available for coarse administrative units, necessitating techniques for fine-scale spatial disaggregation. This paper...

Multivariate statistical analysis of the seismic activity in Morocco using PCA and K-Means clustering

Baraka, Achraf Chakir; Baraka, Kaoutar; Rahmaoui, Mehdi; … - 2026

The rise in seismic waves in Morocco within the last five years prompted an accurate multivariate analysis based on such statistical methods as the classification by the K-Means algorithm and principal component analysis (PCA) of seismic wave quantitative variables for Morocco. The adopted...

Encuestas de posenumeración censal : fundamentos estadísticos para su diseño y análisis

Gutiérrez, Andrés; Babativa-Márquez, Giovany - 2026

Sin duda, la operación estadística más exigente que realizan los Institutos y Oficinas Nacionales de Estadística en los países son los censos de población y vivienda, los cuales se diseñan, entre otros fines, para empadronar y enumerar a todos y cada uno de los habitantes de un país....

Testing models with fat tails via indirect inference

Minford, Patrick; Meenagh, David - 2026

Fat tails can in principle undermine the power of the standard indirect inference test. We examine this issue with Monte Carlo experiments, first for a New Keynesian model solved by the nonlinear algorithm method of Fair and Taylor. Here we find that the standard test has its usual high power,...
