CORRELATION OF DIFFICULTY INDEX AND DISCRIMINATING INDEX IN MEDICAL STUDENT’S ASSESSMENT.
PARIPEX INDIAN JOURNAL OF RESEARCH, 2021Multiple choice questions are nowadays used in competitive examination and formative assessment to assess the student's eligibility and certification.Item analysis is the process of collecting,summarizing and using information from students' responses to assess the quality of test items.Goal of the study was to identify the relationship between the ...

Nonparametric estimation and inference for polytomous discrimination index
Statistical Methods in Medical Research, 2017Polytomous discrimination index is a novel and important diagnostic accuracy measure for multi-category classification. After reconstructing its probabilistic definition, we propose a nonparametric approach to the estimation of polytomous discrimination index based on an empirical sample of biomarker values. In this paper, we provide the finite-sample

Discriminant validity of the Crown–Crisp Experiential Index
British Journal of Medical Psychology, 1987The discriminative power of the CCEI subscales was examined. Several approaches were undertaken on the responses from subjects in three neurotically disturbed groups and a normal control group. Analyses indicated that simple cut‐off points could discriminate effectively an ‘adjusted‐neurotic’ dimension; simple cut‐off points were relatively more ...

Discriminative Validity of the Borderline Syndrome Index
Journal of Personality Disorders, 1993Borderline Syndrome Index (BSI) scores were not significantly different between the following DSM-III-R principal diagnoses: borderline personality disorder (BPD, n = 24), major affective disorder (AD, n = 24), dysthymia (n = 7), and schizophrenia (n = 23).

Machinery Import Discrimination: An Index Number Approach
The Canadian Journal of Economics, 1980It is one of the principles of the General Agreement on Tariffs and Trade that member nations should not discriminate in their tariff schedules by nation of origin. However, exception was made in the case of customs unions. Consequently, the member nations of organizations such as the British Commonwealth and the European Economic Community may ...

Fuzzy Similarity Index For Discrimination Of EEG Signals
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006In this study, a new approach based on the computation of fuzzy similarity index was presented for discrimination of electroencephalogram (EEG) signals. The EEG, a highly complex signal, is one of the most common sources of information used to study brain function and neurological disorders.

Learning Locality Discriminating Indexing for Text Categorization
Fourth International Conference on Fuzzy Systems and Knowledge Discovery (FSKD 2007), 2007This paper introduces a locality discriminating indexing (LDI) algorithm for text categorization. The LDI algorithm offers a manifold way of discriminant analysis. Based on the hypothesis that samples from different classes reside in class-specific manifold structures, the algorithm depicts the manifold structures by a nearest-native graph and a ...

A Density Discriminant Index for Cluster Validation
2019 11th International Conference on Information Technology and Electrical Engineering (ICITEE), 2019Clustering analysis is widely applied in several domains of study. Using a suitable number of clusters is one of the most important factors to influence the performance of clustering. Several algorithms of cluster validation have been developed to find such a number.

Highly discriminating distance-based topological index
Chemical Physics Letters, 1982Abstract A new topological index J (based on distance sums s i as graph invariants) is proposed. For unsaturated or aromatic compounds, fractional bond orders are used in calculating s i . The degeneracy of J is lowest among all single topological indices described so far. The asymptotic behaviour of J is discussed, e.g. when n → ∞ in C n

The development of a colour discrimination index
Lighting Research & Technology, 2017One aspect of colour rendering is to discern the difference between colours and colour discrimination. This is important for applications such as surgical procedures and industrial inspection. Two psychophysical experiments were conducted using computer generated images and real materials, including stone, wood and organs.
