TLDR
In this article, statistical tests permitting the detection of outliers in groups of X-ray intensity measurements are described, which may also be useful for rejecting the outlying counts automatically rather than discard complete sets of measurements.Abstract:
When used to determine the concentrations of chemical elements in samples, X-ray intensity measurements are processed by correction programmes. These measurements are now usually obtained with fully or partially automated instruments. In order to suppress useless computations on sets of results containing rogue values, statistical tests must first be applied to the original experimental data. From an economic standpoint, it may also be worthwhile to reject the outlying counts automatically rather than discard complete sets of measurements. Statistical tests permitting the detection of outliers in groups of results are described.read more

Development of texture and microstructure during cold-rolling and annealing of F.C.C. alloys: Example of an austenitic stainless steel
TL;DR: In this paper, the main brass-type components of the rolling texture are retained, despite classical discontinuous recrystallization and grain growth, and possible solid solution effects (Mo) are invoked to explain this behaviour.

Natural iodine in a clay formation: Implications for iodine fate in geological disposals
Francis Claret,Catherine Lerouge,Thierry Laurioux,Mohamed Bizi,Thibauld Conte,Jean Philippe Ghestem,Guillaume Wille,Tsutomu Sato,Eric C. Gaucher,Eric Giffaut,Christophe Tournassat +10 more
TL;DR: In this article, the ubiquitous presence of iodide at 1 −5 ǫ kg −1 level in the Callovian-Oxfordian (COx) clayy formation was confirmed at a value in the range of ∼20 −40 m −1, i.e. higher than the expected range of radio-iodine concentration in the far field of the storage.

Characterization of plutonium distribution in MIMAS MOX by image analysis
Ghislain Oudinet,Isabelle Munoz-Viallard,Laurence Aufore,Marie-Jeanne Gotta,J.M. Becker,G. Chiarelli,R. Castelli +6 more
TL;DR: In this article, the authors describe the development of X-ray microanalysis techniques to produce semi-quantitative "maps" of plutonium concentrations in order to rapidly characterize large areas of the fuel microstructure with reasonable accuracy.

Procedures for Detecting Outlying Observations in Samples
TL;DR: In this paper, a procedure for determining statistically whether the highest observation, lowest observation, highest and lowest observations, or more of the observations in the sample are statistical outliers is given.
Journal ArticleDOI
Sample Criteria for Testing Outlying Observations
TL;DR: In this article, the significance of the largest observation in a sample of size $n$ from a normal population was investigated and the authors proposed a new statistic, S^2_n/S^2, to test whether the two largest observations are too large.
Journal ArticleDOI
Processing Data for Outliers
TL;DR: In this paper, the authors discussed the problem of whether certain observations properly belong in the presentation of measurements obtained by an experimenter and suggested that a consideration of this sort is more properly made at the recording stage or perhaps at the stage of preliminary processing.

Extension of Sample Sizes and Percentage Points for Significance Tests of Outlying Observations
Frank E. Grubbs,Glenn Beck +1 more
TL;DR: In this article, the probability of a significance test conrerning the highest or lowest observation in normal samples was extended to larger sample sizes than heretofore published and to probability levels of.005 and.001.

Ratios Involving Extreme Values
TL;DR: In this article, order statistics are used to analyze the distribution of order statistics for small values of n = 3, \cdots, 30 and for small samples of size n \leqq 30.
