Modelling & Verifying the models


The data analysis tools are used to build models using data alone. This method uses statistical properties of the data to try and explain the nature of relationship between the variables.

Most of the empirical relationships are developed this way. In general we use curve fitting to fit say a linear or exponential curve to the given data based on its nature. The data analysis tools provide a method to verify and validate the applicability of the chosen model to the given variables. It also provides other information necessary to discriminate between 2 competing models.
