The derivation of Bell inequalities requires an assumption of measurement independence, related to the amount of free will experimenters have in choosing measurement settings. Violation of these inequalities by singlet state correlations brings this assumption into question. A simple measure of the degree of measurement independence is defined for correlation models, and it is shown that all sp...

Given a longitudinal network observed at time points t1 < · · · < tT , tie changes that happen in the interval (th, th+1) typically depend on the networks at t1, . . . , th. In this article we deal with the question whether changes within one interval mutually depend on each other or whether they are conditionally independent, given the previously observed networks. Answering this question for ...

The derivation of Bell inequalities requires an assumption of measurement independence, related to the amount of free will experimenters have in choosing measurement settings. Violation of these inequalities by singlet state correlations, as has been experimentally observed, brings this assumption into question. A simple measure of the degree of measurement independence is defined for correlati...

Markov networks are extensively used to model complex sequential, spatial, and relational interactions in a wide range of fields. By learning the structure of independences of a domain, more accurate joint probability distributions can be obtained for inference tasks or, more directly, for interpreting the most significant relations among the variables. Recently, several researchers have invest...

{In almost all analyses of the least-mean-square (LMS) adaptive lter, it is assumed that the lter coeecients are statistically independent of the input data currently in lter memory, an assumption that is incorrect for shift-input data. In this paper, we present a method for deriving a set of linear update equations that can be used to predict the exact statistical behavior of a nite-impulse-re...

Page 1 of 1 (page number not for citation purposes) In a recent study on nurses’ ability to predict volume status after subarachnoid haemorrhage, we found very low predictive values [1]. In a letter to the editor, Dane [2] argued that an error in statistics ‘makes any reasonable conclusions impossible’. Because Dr Dane was the statistical reviewer of our manuscript, both the authors and the edi...

a fundamental assumption in prosthetic dentistry is that the axis-orbital plane will usually be parallel to the horizontal reference plane. most articulator systems have incorporated this concept into their designs and use orbitale as the anterior reference point for transferring the vertical position of the maxilla to the articulator. clinical observations of cantonese patients suggest that in...
