Deterimine the number of checkpoints for the warmup and sampling, given the desired number of iterations for each and the iterations per checkpoint.
chkpt_setup(iter_sampling, iter_warmup, iter_per_chkpt)(positive integer) The number of post-warmup iterations to run per chain. Note: in the CmdStan User's Guide this is referred to as num_samples.
(positive integer) The number of warmup iterations to run per chain. Note: in the CmdStan User's Guide this is referred to as num_warmup.
(positive integer) The number of iterations per check point.
A list with the following:
warmup_chkpts: Number of warmup checkpoints
sample_chkpts: Number of sampling checkpoints
total_chkpts: Total number of checkpoints
(warmup_chkpts + sample_chkpts)
iter_per_chkpt: Iterations per checkpoint
chkpt_setup <- chkpt_setup(
iter_sampling = 5000,
iter_warmup = 2000,
iter_per_chkpt = 10
)
