     Group instance/class has some important constants:
 
-    -   **supports_batched**
-        Determines whether such variational family can be used for AEVB or rowwise approx.
-
-        AEVB approx is such approx that somehow depends on input data. It can be treated
-        as conditional distribution. You can see more about in the corresponding paper
-        mentioned in references.
-
-        Rowwise mode is a special case approximation that treats every 'row', of a tensor as
-        independent from each other. Some distributions can't do that by
-        definition e.g. :class:`Empirical` that consists of particles only.
-
     -   **has_logq**
         Tells that distribution is defined explicitly

-    **Using AEVB**
-
-    Autoencoding variational Bayes is a powerful tool to get conditional :math:`q(\lambda|X)` distribution
-    on latent variables. It is well supported by PyMC and all you need is to provide a dictionary
-    with well shaped variational parameters, the correct approximation will be autoselected as mentioned
-    in section above. However we have some implementation restrictions in AEVB. They require autoencoded
-    variable to have first dimension as *batch* dimension and other dimensions should stay fixed.
-    With this assumptions it is possible to generalize all variational approximation families as
-    batched approximations that have flexible parameters and leading axis.

     **Delayed Initialization**
 
     When you have a lot of latent variables it is impractical to do it all manually.
