Measurement errorsmay affect the predictor selection of the linear regressionmodel. These effects are studied using ameasurement framework, where the variances of the measurement errors can be estimated without setting too restrictive assumptions about the measurement model. In this approach, the problem of measurement is solved in a reduced true score space, where the latent true score is mult...
In this paper I consider an interpretation of future contingents which motivates a uniication of a Lukiasiewicz-style logic, and the more classical, supervaluational semantics. This in turn motivates a new non-classical logic modelling what is \made true by history up until now". I give a simple Hilbert-style proof theory, and a soundness and completeness argument for the proof theory with resp...
The aim of this study was to compare on an objective basis the results obtained during five classical swine fever (CSF) ring tests conducted in Germany between 1999 and 2003. A novel and simple statistical approach used in behavioural sciences was used. For each ring test, the regional laboratories received a panel of five lyophilized pig sera. The panel contained CSF virus positive and negativ...
Of increasing interest to the educational assessment researchers is the reliability of scores obtained by various measurement procedures like tests, rating scales, surveys, and observation forms. Traditional methods of reliability based on Classical Test Theory (CTT) consider only one source of measurement errors. Generalizability Theory (GT) extends CTT by providing a flexible and practical fr...
In this paper, a size-dependent formulation for the Bernoulli-Euler beam is developed based on a new model of couple stress theory presented by Hadjesfandiari and Dargush. The constitutive equation obtained in this new model, consists of only one length scale parameter that is capable of capturing the micro-structural size effect in predicting the mechanical behavior of the structure. Having on...
In this paper I consider an interpretation of future contingents which motivates a unification of a Łukasiewicz-style logic with the more classical supervaluational semantics. This in turn motivates a new non-classical logic modelling what is “made true by history up until now.” I give a simple Hilbertstyle proof theory, and a soundness and completeness argument for the proof theory with respec...
This paper deals with the reliability of composite measurement consisting of true-false items obeying the Rasch model. A definition of reliability in the Rasch model is proposed and the connection to the classical definition of reliability is shown. As a modification of the classical estimator Cronbach’s alpha, a new estimator logistic alpha is proposed. Finally, the properties of the new estim...
