= List of problems with current implementation of SBVAR and MS-SBVAR =

 * {{{VAROBS}}} should not be necessary (MS-)SBVAR should assume {{{VAROBS = VAR}}} or {{{options_.varobs = M_.endo_names}}}. When {{{VAROBS}}} is present, the order of variables in {{{VAROBS}}} takes precedence over the order in {{{VAR}}} statement.
 * Restriction on the coefficients of the lagged variables precludes Sims-Zha prior
