S-maup: Statistic test to measure the sensitivity to the Modifiable Areal Unit Problem

Authors: Juan C. Duque, Henry Laniado, Adriano Polo

arXiv

This work presents a nonparametric statistical test, $S$-maup, to measure the sensitivity of a spatially intensive variable to the effects of the Modifiable Areal Unit Problem (MAUP). $S$-maup is the...

Avoiding Bias Due to Nonrandom Scheduling When Modeling Trends in Home-Field Advantage

Authors: Andrew T. Karl

arXiv

Existing approaches for estimating home-field advantage (HFA) include modeling the difference between home and away scores as a function of the difference between home and away team ratings that are t...

A Descriptive Study of Variable Discretization and Cost-Sensitive Logistic Regression on Imbalanced Credit Data

Authors: Lili Zhang, Herman Ray, Jennifer Priestley, Soon Tan

arXiv

Training classification models on imbalanced data tends to result in bias towards the majority class. In this paper, we demonstrate how variable discretization and cost-sensitive logistic regression h...

Detecting Changes in Hidden Markov Models

Authors: George V. Moustakides

arXiv

We consider the problem of sequential detection of a change in the statistical behavior of a hidden Markov model. By adopting a worst-case analysis with respect to the time of change and by taking int...

Uncertainty Principle in Distributed MIMO Radars

Authors: Seyed MohammadReza Hosseini, Afshin Isazadeh, Ali Noroozi, Mohammad Ali Sebt

arXiv

Radar uncertainty principle indicates that there is an inherent invariance in the product of the time-delay and Doppler-shift measurement accuracy and resolution which can be tuned by the waveform at...

Modeling Frequency and Severity of Claims with the Zero-Inflated Generalized Cluster-Weighted Models

Authors: Nikola Pocuca, Petar Jevtic, Paul D. McNicholas, Tatjana Miljkovic

arXiv

In this paper, we propose two important extensions to cluster-weighted models (CWMs). First, we extend CWMs to have generalized cluster-weighted models (GCWMs) by allowing modeling of non-Gaussian dis...

Coarse--graining and hints of scaling in a population of 1000+ neurons

Authors: Leenoy Meshulam, Jeffrey L. Gauthier, Carlos D. Brody, David W. Tank, William Bialek

arXiv

In many systems we can describe emergent macroscopic behaviors, quantitatively, using models that are much simpler than the underlying microscopic interactions; we understand the success of this simpl...

Mesoscopic population equations for spiking neural networks with synaptic short-term plasticity

Authors: Valentin Schmutz, Wulfram Gerstner, Tilo Schwalger

arXiv

Coarse-graining microscopic models of biological neural networks to obtain mesoscopic models of neural activities is an essential step towards multi-scale models of the brain. Here, we extend a recent...
