Bayesian Estimation of Marginal Quantiles with Missing Data in a Multivariate Regression Framework [PDF]
EntropyIn this article, we propose and study a class of multivariate regression models that account for ignorable missing data in skewed, potentially heavy-tailed response vectors with positive components.

Semiparametric outcome regression-based estimator of Mann–Whitney-type causal effect [PDF]
BMC Medical Research MethodologyWe introduce a novel semiparametric estimator for Mann–Whitney-type causal effects based on the cumulative probability model (CPM). CPMs are rank-based, invariant to monotone transformations of the outcome, and offer flexible outcome regression under ...

Using threshold Cox models to estimate change points in exposure-response relationships in an occupational epidemiological study of respirable crystalline silica and silicosis risk [PDF]
Frontiers in Public HealthIntroductionIn occupational epidemiology, accurately quantifying exposure-response relationships is crucial.MethodsWe introduce a threshold Cox model that includes a change point term to identify the optimal threshold.

Dual active-set algorithm for optimal 3-monotone regression [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2022 The paper considers a shape-constrained optimization problem of constructing monotone regression which has gained much attention over the recent years. This paper presents the results of constructing the nonlinear regression with $3$-monotone constraints.

Adaptive observer design for time-varying nonlinear systems with unknown polynomial parameters [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2021 Many control methods involve the use of real-time values of the vector of state variables or its estimates. The article considers the problem of state variables observer design for a nonlinear non-stationary plant of a wider class compared to the known ...
