Model Explorer will generate a custom program written in the Econometric Views language. This program will allow you to estimate (and optionally apply standard multicolinearity and heteroskedasticity tests on) every possible regression model mixing a group of independent variables and transformations. Running millions of test regressions and finding the very best is easy with Model Explorer. Furthermore, you can modify the source code generated to include more sophisticated tests or modify the way EViews handles the regressions.
