A reliability index for models
Ecological Modelling, 1981Abstract Since the prediction of environmental changes depends heavily on mathematical models, environmental planners have a definite need for a general test that can be easily applied to determine the reliability of a model or to choose between available models. In this paper a ‘reliability index’ for a model is defined. This index is a number k ⩾ 1

This paper deals with a major challenge in clustering that is optimal model selection. It presents new efficient clustering quality indexes relying on feature maximization, which is an alternative measure to usual distributional measures relying on entropy or on Chi-square metric or vector-based measures such as Euclidean distance or correlation ...

Risk-based target reliability indices for quay walls
Structural Safety, 2018 Design codes and standards rely on generalised target reliability indices. It is unclear, however, whether these indices are applicable to the specific risk-profile of marine structures.

Validity and Reliability Study of the Childbirth Trauma Index
Journal of Nursing Measurement, 2021ObjectiveThe aim of this study is to seek evidence for the validity and reliability of the Childbirth Trauma Index Scale, originally developed by Anderson for adolescents, among women in 18–45 age group.MethodTwo hundred twenty women who were in the postpartum period until 72 hours after birth were included in the study.

Journal of the Engineering Mechanics Division, 1979
The index, β\N, is often used as a measure of second-moment reliability has several limitations. The new index, γ\N, avoids these limitations and has the same numerical value as β\N in elementary cases of second-moment reliability. γ\N is a function of the (generalized) Tchebysheff upper-bound to the probability of failure.

The Edmans ADL index: Validity and reliability
Disability and Rehabilitation, 1997The Edmans ADL index was developed to assess functional abilities in stroke patients, including the activities necessary to enable a person to live independently at home, and graded to enable staff to monitor patient's progress over time. Content validity was established by comparing the Edmans ADL index with other published ADL assessments.

Inter-Rater Reliability of the Strain Index
Journal of Occupational and Environmental Hygiene, 2004The Strain Index is one of several tools available to evaluate exposure to musculoskeletal stressors in the workplace in order to predict whether workers are at an increased risk of developing distal upper extremity disorders. The purpose of this study was to determine the inter-rater reliability of the Strain Index.

Reliable index for measuring information flow
Physical Review E, 2011The estimation of causal relationships from time series data is an important factor in predicting or regulating control in various fields. Usually, when estimating causal relationships, either a causality or a correlation measure is used. However, many studies fail to adequately consider qualitative differences and relations between these measures when

Reliability Indexes of Automated Perimetric Tests
Archives of Ophthalmology, 1988The "reliability" of a subject's automated perimetric test result is generally assessed by three measures: fixation loss and false-positive and false-negative rates. These reliability criteria were examined for 76 glaucomatous and 248 normal subjects who underwent visual field testing (C-30-2 program; Humphrey Visual Field Analyzer, Allergan Humphrey ...

An Alternative Index for the Reliability of Telecommunication Networks
IEEE Transactions on Reliability, 1984A new index for evaluating the reliability of telecommunication networks compares the effectiveness of the modelled actual system with that for an ideal (absolutely failureless) system. The new index is not only general, in that it takes account of all the states and the number of channels between vertices, but the procedure for its calculation allows ...
