The article presents the analytical results of the decision-making by the majority voting algorithm (MVA). Particular attention is paid to the case of an even number of experts. The conditional probabilities of the MVA for two hypotheses are given for an even number of experts and their properties are investigated depending on the conditional probability of decision-making by independent experts of equal qualifications and on their number. An approach to calculating the probabilities of the correct solution of the MVA with unequal values of the conditional probabilities of accepting hypotheses of each statistically mutually independent expert is proposed. The findings are illustrated by numerical and graphical calculations.

Crossing Probabilities

A natural requirement to impose upon the life distribution of a component is that after inspection at some randomly chosen time to check whether it is still functioning, its life distribution from the time of checking should be bounded below by some specified distribution which may be defined by external considerations. Furthermore, the life distribution should ideally be minimal in the partial ordering obtained from the conditional probabilities. We prove that these specifications provide an apparently new characterization of the DFRA class of life distributions with a corresponding result for IFRA distributions. These results may be transferred, using Slepian's lemma, to obtain bounds for the boundary crossing probabilities of a stationary Gaussian process.

Abstract The paper briefly reviews measures that have been proposed since the 1880s to assess accuracy and skill in categorical weather forecasting. The majority of the measures consist of a single expression, for example, a proportion, the difference between two proportions, a ratio, or a coefficient. Two exemplar single-expression measures for 2 × 2 categorical arrays that chronologically bracket the 130-yr history of this effort—Doolittle's inference ratio i and Stephenson's odds ratio skill score (ORSS)—are reviewed in detail. Doolittle's i is appropriately calculated using conditional probabilities, and the ORSS is a valid measure of association, but both measures are limited in ways that variously mirror all single-expression measures for categorical forecasting. The limitations that variously affect such measures include their inability to assess the separate accuracy rates of different forecast–event categories in a matrix, their sensitivity to the interdependence of forecasts in a 2 × 2 matrix, and the inapplicability of many of them to the general k × k (k ≥ 2) problem. The paper demonstrates that Wagner's unbiased hit rate, developed for use in categorical judgment studies with any k × k (k ≥ 2) array, avoids these limitations while extending the dual-measure Bayesian approach proposed by Murphy and Winkler in 1987.

Distribution Feeder

This article presents two methods for predicting weather-related overhead distribution feeder failures. The first model is based on linear regression, which uses a regression function to determine the correlation between the weather factors and overhead feeder failures. The second method is based on a one-layer Bayesian network, which uses conditional probabilities to model the correlation. Both methods are discussed and followed by tests to assess their performance. The results obtained using these methods are discussed and compared.
