Family of the generalised gamma kernels: a generator of asymmetric kernels for nonnegative data
M Hirukawa, M Sakudo - Journal of Nonparametric Statistics, 2015 - Taylor & Francis
Unlike symmetric kernels, so far exploring asymptotics on asymmetric kernels has relied on
diversified approaches. This paper proposes a family of the generalised gamma (GG) …

Optimal asymmetric kernels
KM Abadir, S Lawford - Economics Letters, 2004 - Elsevier
Kernels are typically justified as a smoothing device in nonparametric analysis. We provide
alternative interpretations, which could lead to the use of asymmetric kernels. We thus derive …
