Estimation of the number of failures in the Weibull model using the ordinary differential equation

Hirose, Hideo - In: European Journal of Operational Research 223 (2012) 3, pp. 722-731

In estimating the number of failures using right truncated grouped data, we often encounter cases that the estimate is smaller than the true one when we use the likelihood principle to conditional probability. In infectious disease spread predictions, the SIR model described by simultaneous...

Estimation and model selection for left-truncated and right-censored lifetime data with application to electric power transformers analysis

Emura, Takeshi; Shiu, Shau-Kai - Volkswirtschaftliche Fakultät, … - 2014

In lifetime analysis of electric transformers, the maximum likelihood estimation has been proposed with the EM algorithm. However, it is not clear whether the EM algorithm offers a better solution compared to the simpler Newton-Raphson algorithm. In this paper, the first objective is a...

Statistical mechanics of dielectric breakdown

Vicente, J.L.; Razzitte, A.C.; Cordero, M.C.; Mola, E.E. - In: Physica A: Statistical Mechanics and its Applications 261 (1998) 3, pp. 309-316

A statistical picture of dielectric breakdown in solids is presented and discussed in this paper. The morphology selection mechanism is described by the stochastic model or η model. The approach is formulated in terms of two functions α(η) and β(η), which play the role of a free energy and...
