| Detailed description |
While using the command:estResult <- aidsEst( priceNames, shareNames, "newtotal",
data = mydata, method="LA", hom=T, sym=T, priceIndex = "S", estMethod="SUR" ),
I am getting the error message:
Error in .solve.dgC.lu(as(a, "dgCMatrix"), b = b, tol = tol) :
LU computationally singular: ratio of extreme entries in |diag(U)| = 3.012e-17
> may I know what it explains? |
