Local Linear Multivariate Regression with Variable Bandwidth in the Presence of Heteroscedasticity [PDF]
We present a local linear estimator with variable bandwidth for multivariate nonparametric regression. We prove its consistency and asymptotic normality in the interior of the observed data and obtain its rates of convergence.
