Although there is immense international support for consumer protection, the notion exists that
consumer protection can only exist in developed countries with ample fiscal resources and expertise
to properly act in the ...
We link schizophrenia in families from the genetically isolated South African Afrikaner population to
chromosome 13q (n =51), 1p (n =23) and combined 13q & 1p (n =18). Patients with linkages to chromosome
13q were 4.16 ...

In this paper, we generalize the Wishart distribution utilizing a fresh approach that leads
to the hypergeometric Wishart generator distribution with the Wishart generator and the
Wishart as special cases. Important ...
Immune responses to infection by the human immunodeficiency virus (HIV) and the use of highly active
antiretroviral therapy (HAART) to treat HIV infection, contributes to metabolic irregularities in the host.

Vision is an essential sense and crucial throughout a student’s academic career. Reading and writing
during formal studies require a basic level of visual skills. Training of visual skills to students may
improve the way ...
In this paper the non-central bivariate Kummer-beta type IV distribution is introduced and derived
via the Laplace transform of the non-central bivariate beta distribution by Gupta et al. (2009). We focus
on and discuss ...

Meta-analysis of longitudinal studies combines effect sizes measured at pre-determined
time points. The most common approach involves performing separate univariate metaanalyses
at individual time points. This simplistic ...
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

The Rayleigh distribution, serving as a special case of the Weibull distribution, is
known to have wide applications in survival analysis, reliability theory and commu-
nication engineering. In this paper, Bayesian ...

Heart rate variability (HRV) is an important non-invasive method to quantify stress by
measuring sympathetic and parasympathetic activity of the autonomic nervous system. Few studies
exist on the repeatability and ...
The addition of runs-rules has been recommended to improve the performance of classical,
normal theory Shewhart-type control charts, for detecting small to moderate size shifts. In this
paper, we consider adding both ...
