Because there is no, or little attenuation of the mother's voice, speech and language inside the amniotic fluid (see Introduction), many of their regular, non-random, spectral and temporal characteristics are present.
Natural unstructured scenes are interpreted as realizations of Random Closed Sets (RCSs), whose macroscopic characteristics are mapped.
The material and strength properties in the individual laminae are modeled as 2-D non-Gaussian random fields whose second order probabilistic characteristics are determined from test data.
Markov properties or characteristics are characteristics of random processes in which the conditional probability of a future event depends only on the most recent incident (the present event) and not on past events.
By delineating areas characterized by a typical toposequence, organised and random variability of landscape characteristics is captured in the model.
Missing values in model 3 are assumed to be missing at random, since similar patient characteristics were shown in intervals with missing and non-missing values.
This assumption requires that the individual traits that have determined the choice of initial education are adequately captured by observed pre-determined variables, so that the residual variation in initial education, conditional on these characteristics, is either random or due to temporary circumstances or to factors that do not influence the outcomes of interest.
The non-random selection process due to observed characteristics is controlled by the inclusion of covariates that comprise current and past individual and job characteristics.
The magnitude of a reflection path is not modeled to have a random characteristic, as it is treated as a controlled variable of the study.
Consequently, in order to combine robustness and computational efficiency, the third suite is formed by generating representative artificial accelerograms for the hazard levels considered, where the random characteristics of peak ground acceleration are taken into account.
