(University of Western Cape, 2020)Commercial banks play a dominant role in facilitating the economic growth of a country by acting as an intermediary between the de cit spending unit (borrowers) and the surplus spending unit (lenders). In particular, ... -
Estimation of Pareto distribution functions from samples contaminated by measurement errors
(University of the Western Cape, 2010)The intention is to draw more specific connections between certain deconvolution methods and also to demonstrate the application of the statistical theory of estimation in the presence of measurement error. A parametric ... -
Estimation of Pareto Distribution Functions from Samples Contaminated by Measurement Errors
(University of the Western Cape, 2010)Estimation of population distributions, from samples that are contaminated by measurement errors, is a common problem. This study considers the problem of estimating the population distribution of independent random ... -
Ethionamide pharmacokinetics in multidrugresistant tuberculosis patients with and without HIVinfection
(University of the Western Cape, 2017)Many studies have investigated the pharmacokinetics (PK) of anti-tuberculosis drugs in tuberculosis patients. However, currently in South Africa, no studies have been done on ethionamide (ETH) PK in adult MDR-TB patients ... -
