Reliability and Model Fit

Regression Goodness-Of-Fit Test for Software Reliability Model Validation

Belief Expansion, Contextual Fit, and the Reliability of Information Sources

We develop a probabilistic criterion for belief expansion that is sensitive to the degree of contextual fit of the new information to our belief set as well as to the reliability of our information source. We contrast our approach with the success postulate in AGM-style belief revision and show how the idealizations in our approach can be relaxed by invoking Bayesian-Network models. ∗A slightly...

Bi-level Model for Reliability based Maintenance and Job Scheduling

Many defects in manufacturing system are caused by human resources that show the significance of the human resources in manufacturing systems. Most manufacturers attempt to investigate the human resources in order to improve the work conditions and reduce the human error by providing a proper work-rest schedule. On the other hand, manufacturer deal with machine scheduling based on demand and wo...

Bayesian Measures of Model Complexity and Fit

We consider the problem of comparing complex hierarchical models in which the number of parameters is not clearly defined. Using an information theoretic argument we derive a measure pD for the effective number of parameters in a model as the difference between the posterior mean of the deviance and the deviance at the posterior means of the parameters of interest. In general pD approximately c...

Electroweak Data and Standard Model Fit Results

Most recent tests of the Standard Model of the electroweak interaction are reported using data from the four LEP experiments ALEPH, DELPHI, L3 and OPAL, the SLD experiment at SLC, the Tevatron p¯ p experiments CDF and D0, and the NuTeV neutrino experiment. Consistency of the Standard Model is studied. The value of the Higgs mass is inferred from a global fit. Latest precision electroweak data (...
