when using SVEC to construct the model, I just constantly facing the problems: Error in solve.default(infgamma) : system is computationally singular: reciprocal condition number = 5.60627e-21
this model has 7 variables, and with 4 cointegrations, and I add the LR and SR model as follows:
1.
2.
the follow is the code and i will be appreciated if anyone can help me!!!
vecmmodel<-ca.jo(data,type="trace",ecdet="const",K=3,spec="transitory")
svec<-SVEC(vecmmodel,LR=LR,SR=SR,r=4,lrtest=FALSE,runs=100)
