On a principal varying coefficient model
Web1 day ago · This paper proposes a robust design of the time-varying internal model principle-based control (TV-IMPC) for tracking sophisticated references generated by linear time-varying (LTV) autonomous systems. The existing TV-IMPC design usually requires a complete knowledge of the plant I/O (input/output) model, leading to the lack of … Web15. mar 2024. · In this paper, we introduce a new varying-coefficient partially functional linear quantile regression model, which combines varying-coefficient quantile regression model with functional linear quantile regression model. The functional principal component basis and regression splines are employed to estimate the slope function and varying …

Web20. jun 2024. · Varying coefficient model is often used in statistical modeling since it is more flexible than the parametric model. However, model detection and variable selection of varying coefficient model are poorly understood in mode regression. Existing methods in the literature for these problems are often based on mean regression and … WebABSTRACT. We consider principal varying coefficient models in the high-dimensional setting, combined with variable selection, to reduce the effective number of parameters …
Web28. jan 2003. · Adaptive Varying-Coefficient Linear Models. Varying-coefficient linear models arise from multivariate nonparametric regression, non-linear time series modelling and forecasting, functional data analysis, longitudinal data analysis and others. It has been a common practice to assume that the varying coefficients are functions of a given … Web08. apr 2024. · The above collision force model was based on the point contact theory, and these models are only suitable for conditions where the contact area is small and the recovery coefficient is close to 1. Therefore, Bai and Zhao [ 21 ] and Wang et al. [ 22 ] studied the improved contact force model, respectively, and proposed the models …
Web01. nov 2024. · A principal varying-coefficient model for quantile regression based on regression splines estimation is proposed. Convergence rate and local asymptotics for the coefficient functions are then derived. Furthermore, penalization is used to obtain joint variable selection and dimension reduction in quantile varying-coefficient models.
