Discontinuous Regression Surfaces
We suggest a three-stage procedure to recover discontinuous regression surfaces when noisy data are present. In the rst stage, jump candidate points are detected using a jump detection criterion. A local principal component line is then tted through these points in a neighborhood of a design point. This line provides a rst-order approximation to the true jump location curve in that neighborhood...
متن کاملGeneralized smooth monotonic regression
Common approaches to monotonic regression focus on the case of a unidimensional covariate and continuous dependent variable. Here a general approach is proposed that allows for additive and multiplicative structures where one or more variables have monotone influence on the dependent variable. In addition the approach allows for dependent variables from an exponential family, including binary a...
متن کاملAutomatic Smoothing for Discontinuous Regression Functions
This article proposes an automatic smoothing method for recovering discontinuous regression functions. The method models the target regression function with a series of disconnected cubic regression splines which partition the function’s domain. In this way discontinuity points can be incorporated in a fitted curve simply as the boundary points between adjacent splines. Three objective criteria...
متن کاملDiscontinuous versus Continuous Weaning in Stroke Patients.
BACKGROUND An increasing number of stroke patients have to be supported by mechanical ventilation in intensive care units (ICU), with a relevant proportion of them requiring gradual withdrawal from a respirator. To date, weaning studies have focused merely on mixed patient groups, COPD patients or patients after cardiac surgery. Therefore, the best weaning strategy for stroke patients remains t...
متن کاملBifurcation phenomena in two-dimensional piecewise smooth discontinuous maps.
In recent years the theory of border collision bifurcations has been developed for piecewise smooth maps that are continuous across the border and has been successfully applied to explain nonsmooth bifurcation phenomena in physical systems. However, there exist a large number of switching dynamical systems that have been found to yield two-dimensional piecewise smooth maps that are discontinuou...
