Criterion Item Standard Setting
A method for establishing a minimum passing standard for a multiple choice test is described. The procedure is based on expert judgment about the content of test items. The method can also be used to monitor or adjust a standard that is already in place. The procedure carries advantages that are not available from other approaches to standard setting. It is easy to implement and easy for partic...
متن کاملVus from Kℓ3 Decays
Important progress made this year, both in theory and in experiment, helped solving the problem of 2σ–deviation from the unitarity of the first row elements in the CKM matrix. Today we have, |V us | 2 + |V ud | 2 + |V ub | 2 − 1 = −0.0008(13), −0.0010(13), or −0.0005(13), depending on whether the q 2-dependence of the relevant K ℓ3 form factor is considered as pole-like, linear or quadratic fun...
متن کاملKaon Decays and Vus
Unitarity for the first row of the quark mixing matrix appears to be fully satisfied by the value of V us obtained from recent new measurements of kaon semileptonic decay rates.
متن کاملParametric three-way receiver operating characteristic surface analysis using mathematica.
Three-way receiver operating characteristic (ROC) surface analysis involves the calculation of a volume under an ROC surface (VUS), which is a measure of discriminatory accuracy of 2 diagnostic tests for 3 diseases. Nonparametric methods for calculating VUS and its standard error have been developed. The author presents the code for roc3D, a Mathematica computer program for performing parametri...
متن کامل|Vus| on lattice
Recent lattice studies on (semi-)leptonic kaon decays towards a precise determination of |V us | are reviewed. Attention is given to recent unquenched calculations and consistency of their results with chiral perturbation theory. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
