Moncler Hat previously employed in a flat D
The problem of nonparametric estimation of a multivariate density function is addressed. In particular, a general class of estimators with favorable asymptotic performance Moncler Hat (bias, variance, rate of convergence) is proposed. The proposed estimators are characterized by the flatness near the origin of the Fourier transform of the kernel and are actually shown to be exactly<img height="17" border="0" style="vertical-align:bottom" width="27" alt="" title="" src="http://origin-ars.els-cdn.com/content/image/1-s2.0-S0047259X98917742-si1.gif">-consistent provided the density is sufficiently smooth. Starting from the σ-model conformal invariance conditions we find all four dimensional metrics when the dilaton field satisfies the condition ▿μ▿νφ=0. Such configurations have been previously employed in a flat D dimensional target space and naturally come out as solutions consistent with conformal invariance of the supersymmetric σ-model beyond the two loop order. The four dimensional metrics emerging out are either of the Robertson-Walker type or a special kind of a generalized pp-wave metric.
