.. matvar:: M_.maximum_lag
|br| The maximum number of lags in the model. Note that this value is
computed on the model *after* the transformations related to auxiliary
variables, so in practice it is either 1 or 0 (the latter value corresponds
to a purely forward or static model).
.. matvar:: M_.maximum_lead
|br| The maximum number of leads in the model. Note that this value is
computed on the model *after* the transformations related to auxiliary
variables, so in practice it is either 1 or 0 (the latter value corresponds
to a purely backward or static model).
