Entropy2016,18, 396 outsideW1, andvanishes inU. Defineg′onM′by g′= f1g+ f2g0 onNand g′= f2g0 outsideofN. Since f1+ f2> 0, g′ ispositivedefiniteeverywhereonM′. Since f1 vanishesoutside ofW2,g′ is smoothonM′. Finally, since f1=1and f2=0onU,g′= gonU. We cannowproveTheorem1. LetX be a randomvariable as in Theorem1. Following the notations of the theorem and the lemma, letU = { x∈M,d(x,C)< rinj } . U is open, relatively compactandcontainsC. Let (M′,g′)beas in the lemma.Let fˆ and fˆ ′bethekerneldensityestimators definedonMandM′, respectively. Theorem3.1of [1]provides thedesiredresults for fˆ ′. For r≤ rinj, thesupportandthevaluesonthesupportof fˆ ′and fˆ coincide. Thus, thedesiredresultalsoholdsfor fˆ . References 1. Pelletier,B.KerneldensityestimationonRiemannianmanifolds.Stat. Probab.
