[R] Bootstrap Multivariate Times Series Forecast

Dear Users, Consider a multivariate time series model: a_1*y(t)-...-a_k*y(t-k)=b+[c_1*z(t)-...-c_j*z(t-j)] i.e., a simple multivariate time series model with one exogenous variable. I would like to know what package can I use to do the following, using R: 1) Select k and j jointly; 2) Estimate

Re: [R] SEM error

Dear Jarret, Uwe, and Dan, Sorry -- I missed the initial question. What's a bit odd here is that the singularity occurs only in the computation of the modification indices. It might help to look at the conditioning of the covariance matrix of the parameter estimates (i.e., the eigenvalues or
