tune_for |
Character vector of length one, naming which variable to tune the proposal SDs for: either |
initial_proposal_sds |
Numeric vector with the initial values of the proposal SDs. |
target_acceptance_range |
Numeric vector of length 2 where the first element is the lower bound for the acceptance interval and the second is the upper bound. |
other_param_proposal_sd |
The proposal SD to use for |
max_tuning_cycles |
Maximum number of tuning cycles to perform before returning the proposal SDs as they are. |
initial_rate |
Initial rate at which to mutate the proposal SDs. |
rate_decay |
Geometric rate of decay for size of proposal SD mutation with each successive tuning cycle. |
verbose |
To print execution progress or not. |
... |
Other arguments to be passed to |
Numeric vector of proposal SDs for the different temperature chains.
