Web30 jul. 2002 · 1. Introduction. Finite partially ordered classification models are useful for many statistical applications, including cognitive modelling. When the models are latent and complex, such as in cognitive applications, it becomes imperative to have available a variety of data analytic tools for fitting the models, and for the validation of assumptions that are … The least and greatest element of the whole partially ordered set play a special role and are also called bottom (⊥) and top (⊤), or zero (0) and unit (1), respectively. If both exist, the poset is called a bounded poset. The notation of 0 and 1 is used preferably when the poset is a complemented lattice, and when no confusion is likely, i.e. when one is not talking about partial orders of numbers that already contain elements 0 and 1 different from bottom and top.
