Thanks for your contribution.
How many variables can be processed by the bvar.sv.tvp function ?
I always got the following error whenever I put more than three variables in the function.
It works well if I give it only three or two variables.
Thank you.

Error in solve.default(vbar) : 
  system is computationally singular: reciprocal condition number = 1.15536e-18

Most applications of the model that I know indeed focus on three variables. Given its complexity and flexibility, the model does not appear to scale well to a larger number of variables. Perhaps it helps to reduce the amount of time variation in the model by setting some of the priors accordingly (see Section 2.2 in https://github.com/FK83/bvarsv/blob/master/bvarsv_Nov2015_website.pdf).

Best wishes,
