Description: Implements the Gaussian Kernel Robust Regression (GKRReg / GKRR)
    method proposed by De Carvalho, Lima Neto and Ferreira (2017)
    <doi:10.1016/j.neucom.2016.12.035>. The method re-weights observations
    iteratively using the Gaussian kernel so that poorly-fitted observations
    (outliers, leverage points) receive small weights, yielding resistance to
    Y-space outliers, X-space outliers and leverage points. Convergence is
    guaranteed by Propositions 4.1 and 4.2 of the original paper. Four
    estimators for the kernel width hyper-parameter are provided (S1: Caputo,
    S2: pairwise median, S3: residual variance, S4: corrected Akaike
    bandwidth), together with a data-driven selection rule. Inference is
    provided by a sandwich variance estimator with a family of
    heteroskedasticity-consistent finite-sample corrections adapted to the
    weighted leverage of the method, or by a pairs bootstrap that re-estimates
    the kernel width on each replicate (percentile, normal and bias-corrected
    accelerated intervals with p-values). Six real datasets from the robust
    regression literature are included to facilitate reproducible comparisons.
