Eureqa

Eureqa is a complex application that uses symbolic regression to help you find mathematical functions and dependencies between seemingly random and large data sets. The application can determine the mathematical relationship between large sets of numbers by calculating the closest equation that can compute a certain function. For a data set that must be processed, you can select the complexity of the function to be computed. You can choose which number from the set to use to calculate the equation, a feature that can help you sort independent variables from those leading to dependencies.
