With the help of precisely planned and combined statistical methods otherwise complicated procedures can also be described. A thorough analysis of the area to be studied and comprehended, several ideas describing the causal relations of reality come up the existence of which we assume, that is, we build up a structural model at a theoretical plane. The building of the model is followed by a complex validity survey.

With the help of the valid and approved model, we can substitute values different from the original ones, which allows us to study processes that currently cannot be measured in reality but may occur by certain probability. We can thus obtain relevant and new information with the help of which we can establish our future decisions.

During modelling, it is always to be examined to what extent simulation results can be considered realistic responses of the modelled system. The regular solution in the practice of modelling is to compare simulation results with the values measured on the modelled attribute in the system we want to describe. Simulation can be considered ideally proper and accurate if the measured values and simulation results calculated on the same attribute are the same.

Most Likely Scenarios

With the use of the model with different input values, we can examine several outputs by which we can determine the most likely scenarios.

Association With Correlation

It shows the strength and direction of the relation between two criteria or variables. Its practical use is that during the analysis of a particular element, we can find aspects in the mass of facts that shows similar features to or different from the one we want to examine. For example, the person who has a higher income will spend more on clothing than the person with lower income. It means that there is a positive correlation between the two criteria or variables.

Association Analysis With Linear and Non-linear Regression

The correlation shows only the strength and direction of the relation, whereas regression defines function, so substituting any values we can specify the result of the target value. Using the example we used with correlation, the regression function shows how high expenditure on clothes we can expect with a particular income level.

Pattern Research

After data structuring and using the proper statistical method (cluster analysis), we can explore typical patterns, with the help of which we can define groups specified by particular criteria.
