+Analysis
+========
+
+After using PEtab Select to perform model selection, you may want to operate on all "good" calibrated models.
+The PEtab Select Python library provides some methods to help with this. Please request any missing methods.
+
+See the Python API docs for the :class:`petab_select.Models` class, which provides some methods. In particular, :attr:`petab_select.Models.df` can be used
+to get a quick overview over all models, as a pandas dataframe.
+
+Additionally, see the Python API docs for the ``petab_select.analysis`` module, which contains some methods to subset and group models,
+or compute "weights" (e.g. Akaike weights).
