This H&#8217;ajek projection dominance condition unifies and generalizes several criteria in the existing literature, placing the simple nonparametric jackknife on the same footing as the infinitesimal jackknife in the generalized setting. As an illustration, we apply our result to the two-scale distributional nearest-neighbor regression estimator, obtaining consistent variance estimates under substantially weaker conditions than previously required.<\/div>\n<p> \t<BR><br \/>\n <BR><\/BR><br \/>\n    Jakob R.
