O = BVAR.uncmean(YBar,Mu)
YBar [ numeric ] - Vector of unconditional means imposed as priors.
Mu [ numeric ] - Weight on the dummy observations.
X [ numeric ] - Array with prior dummy observations that can be used in the 'BVAR=' option of the VAR/estimate function.
O [ bvarobj ] - BVAR object that can be passed into the VAR/estimate function.
See the section explaining the weights on prior dummies, i.e. the input argument Mu.
