Bayesian Modal Regression based on Mixture Distributions [PDF]
, 2022 Compared to mean regression and quantile regression, the literature on modal regression is very sparse. A unifying framework for Bayesian modal regression is proposed, based on a family of unimodal distributions indexed by the mode, along with other parameters that allow for flexible shapes and tail behaviors.

Restricted Regression in Networks [PDF]
arXiv, 2023 Network regression with additive node-level random effects can be problematic when the primary interest is estimating unconditional regression coefficients and some covariates are exactly or nearly in the vector space of node-level effects. We introduce the Restricted Network Regression model, that removes the collinearity between fixed and random ...

Does COVID-19-specific news affect stock market liquidity? Evidence from Japan
MethodsX, 2023 This article examines the effect of COVID-19-specific news on stock market liquidity in the Japanese Topix 500-listed firms. Our empirical analyses show that both COVID-19 confirmed cases and COVID-19-specific news induce a negative effect on stock ...

Coefficient Decomposition of Spatial Regressive Models Based on Standardized Variables [PDF]
arXiv, 2022 Spatial autocorrelation analysis is the basis for spatial autoregressive modeling. However, the relationships between spatial correlation coefficients and spatial regression models are not yet well clarified. The paper is devoted to explore the deep structure of spatial regression coefficients.

Tyranny-of-the-minority regression adjustment in randomized experiments [PDF]
arXiv, 2022 Regression adjustment is widely used for the analysis of randomized experiments to improve the estimation efficiency of the treatment effect. This paper reexamines a weighted regression adjustment method termed as tyranny-of-the-minority (ToM), wherein units in the minority group are given greater weights.

A Note On Nonlinear Regression Under L2 Loss [PDF]
arXiv, 2023 We investigate the nonlinear regression problem under L2 loss (square loss) functions. Traditional nonlinear regression models often result in non-convex optimization problems with respect to the parameter set. We show that a convex nonlinear regression model exists for the traditional least squares problem, which can be a promising towards designing ...

Population and species neighbor identity impact trait–trait relationships and plant performance
Population Ecology, EarlyView.We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...
