# Tabs Involved in EstimationΒΆ

In DEDiscover there are 3 tabs that are involved in parameter estimation and displaying the results. They
are prefixed by **Est:**.

- Est: Parameters is where the user selects which parameters are estimated (at least one) and which ones are given fixed values. User also sets initial values of parameters as well as the range of values.
- Est: Methods is where the user decides how the estimation is performed, for instance which optimization algorithm to use, how many iterations to perform, whether we normalize the data when computing the objective function, etc.
- Est: Results is where the user can examine the results of the estimations, and initialize a simulation from those results.
