  • Beta slashed generalised half-normal distribution 
    Kanfer, Frans H.J.; Millard, Sollie M. (South African Statistical Association, 2017)
    In this paper we propose the beta slashed generalised half-normal distribution, which includes some important distributions such as the half-normal, slashed half-normal and generalised slashed half-normal distributions. ...
  • Capital budgeting practices used by selected listed South African firms 
    Hall, J.H. (John Henry); Millard, Sollie M. (Juta, 2010-03)
    This article investigates the application of capital budgeting techniques and the incorporation of risk into the capital budgeting process among a sample of South African industrial firms listed on the JSE Securities ...
  • A comparison of data mining and spatial techniques : an application to property data 
    Hine, T.J.; Millard, Sollie M.; Kanfer, Frans H.J. (South African Statistical Association, 2013-11)
    The improvement of data management and data capturing techniques has led to the availability of large amounts of data for analysis. This is especially true in the field of spatial data, where data is indexed by location. ...
  • Fitting non-parametric mixture of regressions : introducing an EM-type algorithm to address the label-switching problem 
    Skhosana, Sphiwe Bonakele; Kanfer, Frans H.J.; Millard, Sollie M. (MDPI, 2022-05-21)
    The non-parametric Gaussian mixture of regressions (NPGMRs) model serves as a flexible approach for the determination of latent heterogeneous regression relationships. This model assumes that the component means, variances ...
  • Impak van tutoriale op die wiskundeprestasie van eerstejaarstudente 
    Maree, J.G. (Kobus); Louw, Cecilia Jacomina; Millard, Sollie M. (Suid Afrikaanse Akademie vir Wetenskap & Kuns, 2004)
    Historically disadvantaged students in South Africa often underachieve in mathematics due to a number of factors. Action research that was conducted at the (former) Technikon Northern Gauteng to investigate ways in which ...
  • Mixtures of semi-parametric generalised linear models 
    Millard, Sollie M.; Kanfer, Frans H.J. (MDPI, 2022-02-18)
    The mixture of generalised linear models (MGLM) requires knowledge about each mixture component’s specific exponential family (EF) distribution. This assumption is relaxed and a mixture of semi-parametric generalised ...
  • Preliminary test and Bayes estimation of a location parameter under BLINEX loss 
    Coetsee, Judy; Bekker, Andriette, 1958-; Millard, Sollie M. (Taylor and Francis, 2014-09)
    In this article, the preliminary test estimator is considered under the BLINEX loss function. The problem under consideration is the estimation of the location parameter from a normal distribution. The risk under the ...
  • Preliminary testing of the Cobb–Douglas production function and related inferential issues 
    Kleyn, Judy; Arashi, Mohammad; Bekker, Andriette, 1958-; Millard, Sollie M. (Routledge, 2017-01)
    In this article, we consider the multiple regression model in the presence of multicollinearity and study the performance of the preliminary test estimator (PTE) both analytically and computationally, when it is a priori ...
