The model which is solved internally by Dynare is not exactly the
model declared by the user. In some cases, Dynare will introduce
auxiliary endogenous variables --- along with corresponding auxiliary
equations ---, which will appear in the final output.

The main transformation concerns leads and lags. Dynare will perform a
transformation of the model so that there is only one lead and one lag

A similar transformation is done for lags greater than 2 on endogenous
(auxiliary variables will have a name beginning with
@code{AUX_ENDO_LAG}), and for exogenous with leads and lags (auxiliary
variables will have a name beginning with @code{AUX_EXO_LEAG} or
