Test-retest reliability of a new questionnaire on the diet and eating behavior of one year old children
2015
Background As part of a sub-study in the ongoing Norwegian RCT ‘Fit for Delivery’, a new questionnaire, using a combination of food frequency, scale, and categorical questions to gather data on the diets and eating patterns of one year olds, was developed and tested for reliability by test-retest. Results Of 102 parents recruited to the study, 94 completed both test and retest. Correlation coefficients (Spearman’s r, and/or Cohen’s kappa, where applicable) were high for all categories of question, with a mean value of 0.72 for Spearman’s r for food frequency variables, and a mean value of 0.75 for Cohen’s kappa for non-numeric variables such as breast feeding status, showing very high test-…
State Model of Service Reliability
2006
We propose a simple formalism for modelling of a service reliability. A service is defined as an ordered set of states of a modelled application. In the model, a certain reliability is assigned to each application state. Reliability of a service is expressed in terms of above partial reliabilities.
The Comparison of Software Reliability Assessment Models
2015
Abstract The reliability of the software represents one of the most important attributes of software quality, and the estimation of the reliability of the software is a problem hard to solve with accuracy. Nevertheless, in order to manage the quality of the software and of the standard practices in an organization, it is important to achieve an estimation of the reliability as accurate as possible. In the present work there are described the principles and techniques which underlie the estimation of the reliability of the software, starting from the definition of the concepts which express the attributes of software quality. It is taken into account the issue of the estimation of a software…
