  INTRODUCTION : Knowledge of the normal arterial diameter at a given anatomical point is the first step toward quantifying the severity of cardiovascular diseases. According to several studies, parameters such as weight, ...
• From statistical power to statistical assurance : it's time for a paradigm change in clinical trial design 

  Chen, Ding-Geng (Din); Ho, Shuyen (Taylor and Francis, 2017-05)

  A well-designed clinical trial requires an appropriate sample size with adequate statistical power to address trial objectives. The statistical power is traditionally defined as the probability of rejecting the null ...
• A generally weighted moving average chart for time between events 

  Chakraborty, Niladri; Human, Schalk William; Balakrishnan, N. (Taylor and Francis, 2017-05)

  Shewhart-type attribute charts are known to be inefficient for small changes in monitoring nonconformities. An alternative way is to use a time-weighted chart to monitor the time between events (TBE). We propose a one-sided ...
• Preliminary psychometric performance of the Neonatal Feeding Assessment Scale 

  Viviers, Mari; Kritzinger, Alta M. (Aletta Margaretha); Vinck, Bart M.; Graham, Marien Alet (AOSIS OpenJournals, 2017-01-30)

  OBJECTIVE : The objective was to determine the preliminary psychometric performance of a new clinical feeding scale to diagnose oropharyngeal dysphagia (OPD) in neonates. METHODS : Twenty neonates with a median gestational ...
• Correlation between different methods of intra-abdominal pressure monitoring in varying intra-abdominal hypertension models 

  Wise, R.D.; Rodseth, R.N.; Correa-Martin, L.; Sanchez Margallo, F.M.; Becker, Piet J.; Castellanos, G.; Malbrain, M.L.N.G. (Health and Medical Publishing Group, 2017-07)

  BACKGROUND : Advances in intra-abdominal pressure (IAP) measurement have enabled better monitoring and physiological manipulation of patients with intra-abdominal hypertension or abdominal compartment syndrome. This study ...
• A comparison between decomposition rates of buried and surface remains in a temperate region of South Africa 

  Marais-Werner, Anatulie; Myburgh, Jolandie; Becker, Piet J.; Steyn, Maryna (Springer, 2018-01)

  Several studies have been conducted on decomposition patterns and rates of surface remains; however, much less are known about this process for buried remains. Understanding the process of decomposition in buried remains ...
• The impact of the Canterbury Earthquakes on the temporal and spatial patterning of crime in Christchurch, New Zealand 

  Breetzke, Gregory Dennis; King, Marcus; Fabris-Rotelli, Inger Nicolette (Sage, 2018-03)

  The Canterbury Earthquakes struck the Canterbury region of the South Island of New Zealand between September 2010 and February 2011. The Earthquakes resulted in widespread structural damage to Christchurch, the main city ...
• New bivariate gamma types with MIMO application 

  Bekker, Andriette, 1958-; Arashi, Mohammad; Ferreira, J.T. (Johannes) (Taylor and Francis, 2018-01)

  In this paper a bivariate gamma type distribution emanating from the diagonal elements of an inverse Wishart type distribution is developed; which in turn originates from the complex matrix variate elliptical class. From ...
• Beta slashed generalised half-normal distribution 

  Kanfer, F.H.J. (Frans); 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. ...
• New results from a beta-pareto class 

  Makgai, S.L.; Bekker, Andriette, 1958-; Ferreira, J.T. (Johannes); Arashi, Mohammad (South African Statistical Association, 2017)

  In this paper, we propose new results on a beta-Pareto class. This extension evolved by using newly proposed class of beta distributions as generator distributions (F (x)) within the generator-parent approach: H (x) = F ...
• Robust fit of Bayesian mixed effects regression models with application to colony forming unit count in tuberculosis research 

  Burger, Divan Aristo; Schall, Robert (Wiley, 2018-02)

  Early bactericidal activity of tuberculosis drugs is conventionally assessed using statistical regression modeling of colony forming unit (CFU) counts over time. Typically, most CFU counts deviate little from the regression ...
• Characterizing pathology in erythrocytes using morphological and biophysical membrane properties : relation to impaired hemorheology and cardiovascular function in rheumatoid arthritis 

  Olumuyiwa-Akeredolu, Oore-ofe O.; Soma, Prashilla; Buys, A.V. (Antonia Vergina); Debusho, Legesse Kassa; Pretorius, Etheresia (Elsevier, 2017-12)
