A new paradox in random-effects meta-analysis

Authors: Jiandong Shi, Aimin Wu, Tiejun Tong

arXiv

Meta-analysis is an important tool for combining results from multiple studies and has been widely used in evidence-based medicine for several decades. This paper reports, for the first time, an inter...

Bias detection of $PM_{2.5}$ monitor readings using hidden dynamic geostatistical calibration model

Authors: Yaqiong Wang, Minya Xu, Hui Huang, Songxi Chen

arXiv

Accurate and reliable data stream plays an important role in air quality assessment. Air pollution data collected from monitoring networks, however, could be biased due to instrumental error or other...

Person as Population: A Longitudinal View of Single-Subject Causal Inference for Analyzing Self-Tracked Health Data

Authors: Eric Jay Daza

arXiv

Single-subject health data are becoming increasingly available thanks to advances in self-tracking technology (e.g., wearable devices, mobile apps, sensors, implants). Many users and health caregivers...

Optimal decoding of dynamic stimuli encoded by heterogeneous populations of spiking neurons - a closed form approximation

Authors: Yuval Harel, Ron Meir, Manfred Opper

arXiv

Neural decoding may be formulated as dynamic state estimation (filtering) based on point process observations, a generally intractable problem. Numerical sampling techniques are often practically usef...

Can quantum physics help solve the hard problem of consciousness? A hypothesis based on entangled spins and photons

Authors: Christoph Simon

arXiv

The hard problem of consciousness is the question how subjective experience arises from brain matter. I suggest exploring the possibility that quantum physics could be part of the answer. The simultan...

Multi-level hypothesis testing for populations of heterogeneous networks

Authors: Guilherme Gomes, Vinayak Rao, Jennifer Neville

arXiv

In this work, we consider hypothesis testing and anomaly detection on datasets where each observation is a weighted network. Examples of such data include brain connectivity networks from fMRI flow da...

The largest cognitive systems will be optoelectronic

Authors: Jeffrey M. Shainline

arXiv

Electrons and photons offer complementary strengths for information processing. Photons are excellent for communication, while electrons are superior for computation and memory. Cognition requires dis...

Neural System Identification with Spike-triggered Non-negative Matrix Factorization

Authors: Shanshan Jia, Zhaofei Yu, Arno Onken, Yonghong Tian, Tiejun Huang, Jian K. Liu

arXiv

Neuronal circuits formed in the brain are complex with intricate connection patterns. Such complexity is also observed in the retina as a relatively simple neuronal circuit. A retinal ganglion cell re...

False Discovery Rate Controlled Heterogeneous Treatment Effect Detection for Online Controlled Experiments

Authors: Yuxiang Xie, Nanyu Chen, Xiaolin Shi

arXiv

Online controlled experiments (a.k.a. A/B testing) have been used as the mantra for data-driven decision making on feature changing and product shipping in many Internet companies. However, it is stil...

TOP: Time-to-Event Bayesian Optimal Phase II Trial Design for Cancer Immunotherapy

Authors: Ruitao Lin, Robert L Coleman, Ying Yuan

arXiv

Immunotherapies have revolutionized cancer treatment. Unlike chemotherapies, immune agents often take longer time to show benefit, and the complex and unique mechanism of action of these agents render...

An easy-to-use empirical likelihood ABC method

Authors: Sanjay Chaudhuri, Subhro Ghosh, David J. Nott, Kim Cuc Pham

arXiv

Many scientifically well-motivated statistical models in natural, engineering and environmental sciences are specified through a generative process, but in some cases it may not be possible to write d...

Multilevel Monte Carlo Acceleration of Seismic Wave Propagation under Uncertainty

Authors: Marco Ballesio, Joakim Beck, Anamika Pandey, Laura Parisi, Erik von Schwerin, Raul Tempone

arXiv

We interpret uncertainty in a model for seismic wave propagation by treating the model parameters as random variables, and apply the Multilevel Monte Carlo (MLMC) method to reduce the cost of approxim...

Linearity versus non-linearity in high frequency multilevel wind time series measured in urban areas

Authors: Luciano Telesca, Mohamed Laib, Fabian Guignard, Dasaraden Mauree, Mikhail Kanevski

arXiv

In this paper, high frequency wind time series measured at different heights from the ground (from 5.5 to 25.5 meters) in an urban area were investigated. The spectrum of each series is characterized...

The Efficiency of Geometric Samplers for Exoplanet Transit Timing Variation Models

Authors: Noah W. Tuchow, Eric B. Ford, Theodore Papamarkou, Alexey Lindo

arXiv

Transit timing variations (TTVs) are a valuable tool to determine the masses and orbits of transiting planets in multi-planet systems. TTVs can be readily modeled given knowledge of the interacting pl...

A computationally efficient correlated mixed Probit for credit risk modelling

Authors: Elisa Tosetti, Veronica Vinciotti

arXiv

Mixed Probit models are widely applied in many fields where prediction of a binary response is of interest. Typically, the random effects are assumed to be independent but this is seldom the case for...
