Document data-command or replace it
Currently, to get a dseries
object loaded into estimation, we use
ts = dseries('fsdat_simul.m');
data(series=ts, first_obs=1950Q3, last_obs=2000Q3);
(see https://git.dynare.org/Dynare/dynare/-/blob/master/tests/dates/fs2000.mod). But that data
-command is not documented as it belongs to the new estimation interface (#226). The documentation at https://archives.dynare.org/DynareWiki/NewEstimation seems outdated.
