TL;DR: A general statistical methodology for the analysis of multivariate categorical data arising from observer reliability studies is presented and tests for interobserver bias are presented in terms of first-order marginal homogeneity and measures of interob server agreement are developed as generalized kappa-type statistics.
Abstract: This paper presents a general statistical methodology for the analysis of multivariate categorical data arising from observer reliability studies. The procedure essentially involves the construction of functions of the observed proportions which are directed at the extent to which the observers agree among themselves and the construction of test statistics for hypotheses involving these functions. Tests for interobserver bias are presented in terms of first-order marginal homogeneity and measures of interobserver agreement are developed as generalized kappa-type statistics. These procedures are illustrated with a clinical diagnosis example from the epidemiological literature.

TL;DR: In this article, the authors present guidelines for choosing among six different forms of the intraclass correlation for reliability studies in which n target are rated by k judges, and the confidence intervals for each of the forms are reviewed.
Abstract: Reliability coefficients often take the form of intraclass correlation coefficients. In this article, guidelines are given for choosing among six different forms of the intraclass correlation for reliability studies in which n target are rated by k judges. Relevant to the choice of the coefficient are the appropriate statistical model for the reliability and the application to be made of the reliability results. Confidence intervals for each of the forms are reviewed.

TL;DR: The goal for this study was to develop a measure of balance appropriate for elderly individuals and there was a high degree of internal consistency, a Cronbach's alpha of .96, which indicates the movements reflect a single underlying dimension.
Abstract: The goal for this study was to develop a measure of balance appropriate for elderly individuals. In total, 38 patients, ranging in age from 60 to 93 years, and 32 professionals, including nurses, physicians, and physical and occupational therapists were surveyed in three distinct phases to develop the content. Reliability of the measure was assessed by having physical therapists evaulate the videotaped performances of geriatric subjects at two different points in time. The intraclass correlation coefficients measuring the inter and intra rater reliability for the test as a whole were .98 and .99 respectively. The correlation coefficients for the individual items ranged from .71 to .99. In addition, there was a high degree of internal consistency, a Cronbach's alpha of .96, which indicates the movements reflect a single underlying dimension. The scale consists of 14 movements common in everyday life. It is easy to administer and score and has measurement properties that are better than expected for a new i...

TL;DR: In this article, a load model, generation system, and transmission network which can be used to test or compare methods for reliability analysis of power systems is described. But the authors focus on the reliability of the power system and do not consider the transmission system.
Abstract: This report describes a load model, generation system, and transmission network which can be used to test or compare methods for reliability analysis of power systems. The objective is to define a system sufficiently broad to provide a basis for reporting on analysis methods for combined generation/transmission (composite) reliability.

TL;DR: Definition: To what extent does the study allow us to draw conclusions about a causal effect between two or more constructs?
Abstract: Definition: To what extent does the study allow us to draw conclusions about a causal effect between two or more constructs? Issues: Selection, maturation, history, mortality, testing, regression towrd the mean, selection by maturation, treatment by mortality, treatment by testing, measured treatment variables Increase: Eliminate the threats, above all do experimental manipulations, random assignment, and counterbalancing.
