SLEEP EVALUATION IN HUMANS HAS BEEN USUALLY PERFORMED WITH POLYSOMNOGRAPHY (PSG), A TECHNIQUE CONSIDERED THE GOLD STANDARD FOR SLEEP STUDIES. In fact, PSG has been used in clinical trials in spite of its limitations for longitudinal and more naturalistic studies. Actigraphs, instruments to measure wrist motor activity and also called activity monitors, provide an indirect assessment of sleep th...

On the basis of 2200 small (10-100) samples obtained from four random number populations, it is shown that the rank correlation coefficient, p, is 88 adequate a measure of concordance 88 the Pearson product-moment correlation, T. The samples were obtained by using pseudo-random linear and normal number generators for bivariate populations with expected correlation cC'efficientB, r~, of 0.0 and ...

Abstract Preference data are a particular type of ranking where some subjects (voters, judges,...) express their preferences over set alternatives (items). In most real life cases, items receive the same preference by judge, thus giving rise to with ties. An important issue involving rankings concerns aggregation into “consensus”. The purpose this paper is investigate consensus between ties, ta...

We consider the hedging problem in a jump-diffusion market with correlated assets. For this purpose, we employ the locally risk-minimizing approach and obtain the hedging portfolio as a solution of a multidimensional system of linear equations. ‎This system shows that in a continuous market, independence and correlation assumptions of assets lead to the same locally risk-minimizing portfolio. ‎...

The Pearson correlation coefficient (PCC) and the Mander's overlap coefficient (MOC) are used to quantify the degree of colocalization between fluorophores. The MOC was introduced to overcome perceived problems with the PCC. The two coefficients are mathematically similar, differing in the use of either the absolute intensities (MOC) or of the deviation from the mean (PCC). A range of correlate...

many researches have depicted there is no significant and positive correlation between it and firm level performance, called productivity paradox, so as successful investment on it depends on taking into account the role of complementary assets such as business processes and organizational infrastructures. on the other hand, since there are not enough resources to invest on all these assets, th...
