object |
A varstan object of the time series fitted model. |
permuted |
A logical scalar indicating whether the draws after the warmup period in each chain should be permuted and merged. If FALSE, the original order is kept. For each stanfit object, the permutation is fixed (i.e., extracting samples a second time will give the same sequence of iterations). |
A real value with the accumulated log likelihood.
