Modified BIC for Model Selection in Linear Mixed Models
… In this dissertation, we propose a modified BIC for model selection with linear mixed effects models that can solve the case when the variance components are on the boundary of the parameter space. We first derive a modified BIC to choose random effects assuming that the random effects are …

Performance of the Kenward-Project when the Covariance Structure is Selected Using AIC and BIC
… structure. Information criteria, such as AIC and BIC, are often used by statisticians to help with this task. However, these criteria do not always point to the true covariance structure and therefore the wrong covariance structure is sometimes chosen. Once this step is complete, Wald statistics …

Model selection in rheology: Providing a practical framework, surveying the field, and assessing the uses and limitations of BIC
… such as the Bayesian Information Criterion (BIC) may add significant value and validity to these analyses. There remains even greater opportunity in the application of more sophisticated methods such as the calculation of Bayes Factors and the formulation of priors for rheological models. The …

An Evaluation of the use Patterns of a Specialised Information Centre in Biodeterioration
… SIC was the Biodeterioration Information Centre (BIC) and it has gradually developed a range of services for the biodeterioration community. Its service development was accompanied by investigations into BIC organisation and input but the present study is the first to evaluate BIC services and …

Criteria for evaluating model deficiency for groundwater models and the effects of eliminating deficient models on multi-model analysis using AICC, KIC, AIC, and BIC
… to evaluate how components of AIC, AICc, BIC, and KIC rank models and assign model probabilities, and to demonstrate how removing deficient models improves MMA results. Synthetic models are used to represent true but unknown systems in contrast to experimental models that are created to …

Best Interests Of The Child Principle In The Context Of Parent Separation Or Divorce : As Conceptualised By The Community
Best interests of the child (BIC) is a construct that is central to legal decisions in several areas including parenting matters in the Family Courts, guardianship, child-protection, and adoption. Despite the centrality of the construct, BIC has not been operationalised (Thomson & Molloy, 2001) and …

Detectivity vs. Sensitivity: Non-Hermitian Metasurface Sensor
… forming a quasi bound state-in-the-continuum (BIC). The plasmonic BIC sensors show higher detectivity but smaller sensitivity. We identify the physics behind this trade-off and experimentally demonstrate antimouse-IgG sensing in a gold nano-disk array-based plasmonic BIC sensor. Moreover, we …

Bayesian model determination for categorical data survey
… factors and the Bayesian Information Criterion (BIC) approximation have been offered as alternative approaches. These Bayesian methods are reviewed, and comparisons made between their performance. The effect of ignoring the complex sampling design is investigated. Moreover, adjustments to the …
