Assessing linearity in high dimensions
Some standard numerical problems become intractable in high dimensions. Yet successes are often achieved in practice. This may be explained in terms of the underlying target function being somehow simpler than assumed in the intractability arguments. A prototypical form of simplicity is approximate linearity. In moderate dimensions linearity can be investigated by linear regression. In very hig...
متن کاملRecognising and assessing victims of torture in emergency departments.
A wall of silence surrounds torture. This silence, shame and humiliation is just what the torturer depends on. It is important to remember this when a survivor (refugee or asylum seeker) whose life has been damaged and destroyed in many ways is being assessed in the A&E department. Over 5,000 people per month seek refuge in the UK, many of whom will have suffered torture, leaving them physicall...
متن کاملTesting time series linearity: traditional and bootstrap methods
We review the notion of time series linearity and describe recent advances in linearity and Gaussianity testing via data-resampling methodologies. Many advances have been made since the first published tests of linearity and Gaussianity by Subba Rao and Gabr in 1980, including several resampling-based proposals. This article is intended to be instructive in explaining and motivating linearity t...
متن کاملStatistical methods for evaluating the linearity in assay validation
J. Chemom One of the most important characteristics for evaluation of the accuracy in assay validation is the linearity. Kroll, et al. [1] proposed a method based on the average deviation from linearity (ADL) to evaluate the linearity. Hsieh and Liu [2] suggested that hypothesis for proving the linearity be formulated as the alternative hypothesis and proposed the corrected Kroll’s method. Howe...
متن کاملInvestigations on the Linearity of Indirect Effects with Different Methods
The tests were carried out on a carbonfibre reinforced structure with a number of wires with different kind of installation. The peak value of the current impulses ranges from 20 kA up to 200 kA and the comparison shows, that a reasonable linearity exists for carbonfibre reinforced material and that the deviations are always on the save side. The verification of the linearity has been checked t...
