An Illuminating Counterexample
because S is “unbiased” and T 2 is “biased.” That means E(S) = σ 6= E(T ), i.e., an “unbiased estimator” is a statistic whose expected value is the quantity to be estimated. The goodness of an estimator is sometimes measured by the smallness of its “mean squared error,” defined as E ( ([estimator]− [quantity to be estimated]) ) . By that criterion the biased estimator T 2 would be better than t...
متن کاملTraverse Analysis
Traversing is a fundamental operation in surveying and the assessment of the quality of a traverse is a skill that every surveyor develops. Acceptable traverses have angular and linear misclosures that fall within acceptable bounds; which would permit the adjustment of the traverse measurements to remove mathematical inconsistencies. Unfortunately these misclosures tell very little about the pr...
متن کاملLanthanide-tagged proteins--an illuminating partnership.
Lanthanide-tagged proteins are valuable for exploiting the unique properties of Ln ions for investigating protein structure, function, and dynamics. Introduction of the Ln into the target is accomplished via chemical modification with synthetic lanthanide-chelating prosthetic groups or by coexpression with peptide-based binding tags. Complexed Ln-tags offer a heavy-atom site for solving the pha...
متن کاملIlluminating an Ecosystem of Partisan Websites
This paper aims to shed light on alternative news media ecosystems that are believed to have influenced opinions and beliefs by false and/or biased news reporting during the 2016 US Presidential Elections. We examine a large, professionally curated list of 668 hyper-partisan websites and their corresponding Facebook pages, and identify key characteristics that mediate the traffic flow within th...
متن کاملAn observational model for illuminating isolated scratches
In this paper we present an observational model for rendering isolated scratches on otherwise smooth surfaces. Current illumination models do not provide a simple method for approximating the e ect caused by these isolated scratches. One way to model the e ect of these scratches is to consider them as single slits. The observed intensity at a point is then computed using Fresnel single slit di ...
