The predictive validity of safety climate
Journal of Safety Research, 2007Safety professionals have increasingly turned their attention to social science for insight into the causation of industrial accidents. One social construct, safety climate, has been examined by several researchers [Cooper, M. D., & Phillips, R. A. (2004). Exploratory analysis of the safety climate and safety behavior relationship.

Validation of Probabilistic Predictions
Medical Decision Making, 1993Current advances in high-speed computing and increased availability of statistical software have led to widespread use of statistical methods for the development of computerized protocols predictive of binary health outcomes. If these predictive algorithms are to be used in settings other than those for which they were developed, e.g., applied in a ...

Validating and comparing predictive models
International Journal of Food Microbiology, 1999The bias and accuracy factors introduced by Ross [Ross, T., 1996. Indices for performance evaluation of predictive models in food microbiology. J. Appl Bacteriol. 81, 501-508] for the evaluation of the performance of models in 'predictive food microbiology' are refined by basing the calculation of those measures on the mean square differences between ...

Model Selection by Predictive Validation
Pattern Analysis & Applications, 2002: Gaussian mixture modelling is used to provide a semi-parametric density estimate for a given data set. The fundamental problem with this approach is that the number of mixtures required to adequately describe the data is not known in advance.

Validity of Biorhythms for Predicting Death
The Journal of Psychology, 1982Summary The theory of biorhythms, supported by some studies and contradicted by others, states that people's lives are affected by a physical, an emotional, and an intellectual cycle or rhythm. The present study used chi-square analyses to investigate the various possible combinations of critical and noncritical days and to test whether death tends to ...

Cross-Validation and Multinomial Prediction
Biometrika, 1974Good (1965) and Fienberg & Holland (1972, 1973) have addressed the problem of smoothing multinomial frequencies as one of estimation of the probabilities in the traditional multinomial probability model. Suppose the multinomial has t categories and that the corresponding observed frequencies are n1, ..., nt with In, = N. Concerned with the case when at

The Predictive Validity of the Pediatric Trauma Score
The Journal of Trauma: Injury, Infection, and Critical Care, 1987The Pediatric Trauma Score was evaluated in 450 injured children by a paramedic in the field and a physician in an E.D. There was agreement between the scores of these two individuals 93.6% of the time, correlation coefficient 0.991, r2 = 0.982. Further testing at the 0.01 level of significance indicated that a positive association existed between ...
