    • A semi-parametric method for transforming data to normality 

      Koekemoer, Gerhard; Swanepoel, Jan W.H. (Springer, 2008)
      A non-parametric transformation function is introduced to transform data to any continuous distribution. When transformation of data to normality is desired, the use of a suitable parametric pre-transformation function ...
    • Transformation Kernel density estimation with applications 

      Koekemoer, Gerhard; Swanepoel, Jan W.H. (Taylor & Francis, 2008)
      One of the main objectives of this article is to derive efficient nonparametric estimators for an unknown density fX. It is well known that the ordinary kernel density estimator has, despite several good properties, some ...
