  • Asymptotics for general multivariate kernel density derivative estimators 
    Chacon Jose; Duong Tarn; Wand Matthew (Academia Sinica, 2011)
    We investigate kernel estimators of multivariate density derivative functions using general (or unconstrained) bandwidth matrix selectors. These density derivative estimators have been relatively less well researched than ...
  • Feature significance for multivariate kernel density estimation 
    Duong Tarn; Cowling Arianna; Koch Inge; Wand Matt (Elsevier, 2008)
    Multivariate kernel density estimation provides information about structure in data. Feature significance is a technique for deciding whether features¿such as local extrema¿are statistically significant. This paper proposes ...
  • Highest density difference region estimation with application to flow cytometric data 
    Duong Tarn; Koch Inge; Wand Matt (Wiley - VCH Verlag GmbH & Co. KGaA, 2009)
    Motivated by the needs of scientists using flow cytometry, we study the problem of estimating the region where two multivariate samples differ in density. We call this problem highest density difference region estimation ...
