Hierarchical data models are commonly used in databases to represent data across a multitude of disciplines. In this paper, I will examine two models that can be used to represent hierarchical data in a relational database, the nested interval model,

Hierarchical data are found in a variety of database applications, including content management categories, forums, business organization charts, and product categories. In this paper, we will examine two models deal with hierarchical data in relatio

Publisher Summary Trees are often drawn as boxes-and-arrows charts that tend to fix the mental image of a tree into a graph structure. Another way of representing trees is to show them as nested sets. The chapter highlights this approach. To show a t

In regression, model averaging (MA) provides an alternative to model selection (MS), and asymptotic efficiency theories have been derived for both MS and MA. Basically, under sensible conditions, MS asymptotically achieves the smallest estimation los

Bayes factors allow researchers to test the effects of experimental manipulations in within-subjects designs using mixed-effects models. van Doorn et al. (2021) showed that such hypothesis tests can be performed by comparing different pairs of models

In this article, we propose new tests of equal predictive ability between nested models when factor-augmented regressions are used to forecast. In contrast to the previous literature, the unknown factors are not estimated by principal components but

Coastal regions are vulnerable areas with often high population density, as well as tourism and maritime activities that may have negative impact on the environment. From a physical point of view, coastal areas may be characterized by high gradient t

Global motion and global form are proposed to be processed through functionally differentiated independent channels along dorsal (motion) and ventral (form) pathways. However, more recent studies show significant interactions between these pathways b
