Several correlations among observables derived from modelling the high-energy properties of GRBs have been reported in the literature. We show that well-known examples of these have common features indicative of an origin in selection effects. In particular, we focus here on the possible origin of the Epk-Eiso correlation in Swift data due to detector threshold truncation. The existence of fain...

In some biomedical studies, biomarkers are measured repeatedly along some spatial structure or over time and are subject to measurement error. In these studies, it is often of interest to evaluate associations between a clinical endpoint and these biomarkers (also known as functional biomarkers). There are potentially two levels of correlation in such data, namely, between repeated measurements...

In this paper we study the pseudorandomness of finite binary sequences derived from linear recursions. We show, that the well-distribution measure is small. Furthermore we also show that the correlation measures are small for small correlation orders, but if the order of the correlation is greater than the order of the linear recursion, then the correlation can be large. 2000 Mathematics Subjec...
