That is to say, in addition to the predicates constructed with conventional propositional operators (and or, there is equality and predicates composed of existentially quantified variables and universally quantified ones. The B method is based on the notion of abstract machines.
The existential quantifier, symbolized, expresses that the formula following holds for some (at least one) value of that quantified variable.
If '∃x Human(x)' entails not only that humans exist, but that humanity exists, then it is ontologically committed to properties or universals, even though no property or universal is the value of any quantified variable.
For this, OLS estimations are considered appropriate to analyze and quantify observable variables of innovation processes; however, for dynamic effects, these methods often lead to problems of causality, endogeneity, and selectivity.
The visual outcome of a micromodel experiment is the subject of further image processing/analysis studies that quantify the variables of interest such as fluid saturation and other morphological features.
Based on the regression analysis on simulation results, a mathematical expression was proposed to quantify e/E, involving variables of J and Rr, where Rr is the radius of truncating circles centered at an intersection.
The pattern of random differences was quantified using the variable of relative rank variance (RV).
Second, by assembling a series of variables quantifying the distribution of different pig types in the country and anthropogenic factors, we also aimed to carry out a first investigation of the risk factors most strongly associated with all PRRS occurrences, possibly including HP-PRRS in Thailand.
There are two main problems with this way of quantifying latent variables.
For instance, in the case of assessing tie strengths, observational studies may be more accurate in quantifying duration and frequency variables of a relationship, while surveys can provide qualitative insights into depth and intimacy [95, 96].
