the functions must be given. To this end CE simulation is performed. Data
processing consists of revealing the logical dependencies which coincide with
theoretical functions derived by the simulation of different types of CE relations.
As a result, an appropriate function is chosen and the formula expressing the CE
relation in the system under study, e.g., in the system climate-ocean-sediments,
is constructed. Before data processing, data formalization is fulfilled.

Data Formalization
CE simulation is based on mathematical logic including as main elements the
notions proposition and predicate (proposition related to objects). Thus, to use
these tools, available data have to be in the shape of propositions concerning attributes of natural phenomena. Depending on the kinds of data, there are different ways for such representation, as shown in Table 1.
