We study the estimation of moments and joint moments of microstructure noise. Estimators of arbitrary order of (joint) moments are provided, for which we establish consistency as well as central limit theorems. In particular, we provide estimators of auto-covariances and auto-correlations of the noise. Simulation studies demonstrate excellent performance of our estimators even in the presence o...

Process control systems typically involve many variables that can be intercorrelated with each other (cross-correlated), correlated with themselves over time (auto-correlated), and that are represented by displays possessing varying degrees of reliability. This study examined these factors in an information integration task which compared the relative advantages of integral and separable displa...

Interactions between cytokines and others soluble factors (hormones, antibodies...) can play an important role in the development of thyroid pathogenesis. The purpose of the present study was to examine the possible correlation between serum cytokine concentrations, thyroid hormones (FT4 and TSH) and auto-antibodies (Tg and TPO), and their usefulness in discriminating between different thyroid ...

because of heavy competition between auto manufacturer and the threats of foreign companies, they try to reduce the internal competition and costs by cooperation and merge. estimation about the auto market is affected by supply and demand. the demand depends on two factors: need for new cars and old cars exit. and the supply depends on production capacity and export. key factors that affected o...

Here we argue that the probability a given source produces exactly single photon is natural quantity to benchmark single-photon sources as it certifies absence of multi-photon components and quantifies efficiency simultaneously. Moreover, this can be bounded simply from an auto-correlation measurement — balanced beam splitter two detectors. Such bound gives access various non-classicality witne...
