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 the model; 2) Forecast h=4 steps ahead the estimated model; 4) Bootstrap the forecast, since my sampl...

...n places. For instance, in equation (3) it looks to me like a measure with two free variables (i and j) is being defined in terms of two free variables (j and m) and one bound one (i). Is the summation actually supposed to be over m? (Then within the summation x_i is a dw dimensional vector, as is c_j, ie they're both feature vectors, one representing a single item and one representing a cluster centroid.) I may be misreading something fundamentally here, because aspects of the combined algorithm just don't make sense to me. It doesn't help my understanding that the paper seems to u...
