Investigation of outliers of evaluation scores among school of health instructors using outlier - determination indices
Introduction: Teacher evaluation, as an important strategyfor improving the quality of education, has been considered byuniversities and leads to a better understanding of the strengthsand weaknesses of education. Analysis of instructors’ scoresis one of the main fields of educational research. Since outliersaffect analysis and interpretation of information processes bothstructurally and concep...

15 صفحه اولBayesian Identi cation of Outliers in Computerized Adaptive Tests
We consider the problem of identifying examinees with aberrant response patterns in a computerized adaptive test (CAT). The vector of responses yi of person i from the CAT comprise a multivariate response vector. Multivariate observations may be outlying in many di erent directions and we characterize speci c directions as corresponding to outliers with di erent interpretations. We develop a cl...
متن کاملOutlier-Tolerant Fitting and Online Diagnosis of Outliers in Dynamic Process Sampling Data Series
Outliers as well as outlier patches, which widely emerge in dynamic process sampling data series, have strong bad influence on signal processing. In this paper, a series of recursive outlier-tolerant fitting algorithms are built to fit reliably the trajectories of a non-stationary sampling process when there are some outliers arising from output components of the process. Based on the recursive...
متن کاملRobust exogeneity tests in the presence of outliers
Exogeneity testing is studied in the presence of outliers in response variables. Robust tests based on least absolute deviations (LAD) and M estimators are proposed and illustrated with an application to Mroz (1987) data. Our simulation results show that the proposed robust tests outperform the traditional Hausman test for exogeneity in terms of empirical power in the presence of outliers in re...
