  • 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 ...
  • Ormerod, John; Koch, Inge; Wand, Matt (Physica-Verlag Gmbh & Co, 2008)
    We study computational issues for support vector classification with penalised spline kernels. We show that, compared with traditional kernels, computational times can be drastically reduced in large problems making such ...
