WebLinear regression is cheap. Doing two linear regressions for each pair of smoothing splines, instead of just one, may yield faster convergence. Once we have the partial residuals based on both the ordinary regressors and the two smoothing splines, we start all over again. ESL suggests that it is computationally desirable to renormalize the f˜ Web12 Mar 2024 · Mixed estimators in nonparametric regression have been developed in models with one response. The biresponse cases with different patterns among predictor variables that tend to be mixed estimators are often encountered. Therefore, in this article, we propose a biresponse nonparametric regression model with mixed spline smoothing …
