The kernel smoothed Nelson–Aalen estimator has been well investigated, but is unsuitable when some of the censoring indicators are missing. A representation introduced by Dikta, however, facilitates hazard estimation when there are missing censoring indicators. In this article, we investigate (i) a kernel smoothed semiparametric hazard estimator and (ii) a kernel smoothed “pre-smoothed” Nelson ...

Adult cardiovascular disease has its roots in childhood, Various surveys have shown a significant correlation between early atherosclerotic changes indentified at autopsy of children and young adults, and both total cholesterol (TC) and low-density lipoprotein (LDL cholesterol) levels. The hypercholesterolemic neonates time for diagnosis of high risk neonate infants. The aim of this study is to...

OBJECTIVE To assess the prevalence of human immunodeficiency virus (HIV) and pulmonary tuberculosis (PTB) in the study population in Delta State of Nigeria. METHODS Two hundred and five patients suspected of HIV and TB were prospectively studied in Kwale, Agbor and Eku in Delta State of Nigeria from February 2006 to February 2008. Human immunodeficiency virus status was determined using World...

Nelson algebras arise naturally in algebraic logic as the algebraic models of Nelson’s constructive logic with strong negation. This note gives two characterisations of the variety of Nelson algebras up to term equivalence, together with a characterisation of the finite Nelson algebras up to polynomial equivalence. The results answer a question of Blok and Pigozzi and clarify some earlier work ...

according to the recent literature, the expansion of intra-industry trade increases the intra-industrial excess job reallocation. based on lovely and nelson (2002), this study examined the hypothesis that marginal intra-industry trade has a positive effect on the excess job reallocation in iranian industries. therefore, we have employed a panel technique for iranian manufacturing industries at ...
