Make sure that the diagnosis of active configuration. Otherwise, press [2] [0]) (catalog, press the letter "D" and scroll until you see the symbolic DiagnosticOn too. These exports, and a message "Done" appears.
In the submenu Calc ([stat]> Calc), you should see the other options QuadReg, CubicReg, QuartReg, etc. go through each and check the correlation coefficient (r). What does the test regression, a correlation coefficient close to 1 or -1 will generate the best solution.
If you scroll down, if the option of linear regression, the TI-83, I have a quadratic, cubic, and I think the fifth year, and the ability of the exponential regression. If you want to customize the type of regression, you need a bit of linear algebra, and I doubt you're still here. (Maybe you do not know ....)
