  • Kurtosis of the logistic-exponential survival distribution 
    Van Staden, Paul Jacobus; King, Robert A.R. (Taylor and Francis, 2016-01)
    In this article, the kurtosis of the logistic-exponential distribution is analyzed. All the moments of this survival distribution are finite, but do not possess closed-form expressions. The standardized fourth central moment, ...
  • Modeling of generalized families of probability distribution in the quantile statistical universe 
    Van Staden, Paul Jacobus (University of Pretoria, 2013)
    This thesis develops a methodology for the construction of generalized families of probability distributions in the quantile statistical universe, that is, distributions specified in terms of their quantile functions. ...
  • Quantile-based generalized logistic distribution 
    Omachar, Brenda V. (University of Pretoria, 2014)
    This dissertation proposes the development of a new quantile-based generalized logistic distribution GLDQB, by using the quantile function of the generalized logistic distribution (GLO) as the basic building block. This ...
  • The quantile-based skew logistic distribution 
    Van Staden, Paul Jacobus; King, Robert A.R. (Elsevier, 2015-01)
    We show that the quantile-based skew logistic distribution possesses kurtosis measures based on L-moments and on quantiles which are skewness invariant. We furthermore derive closed-form expressions for method of L-moments ...
