Generate a list of settings for automated factor slice sampling

Description

Generate a list of settings for automated factor slice sampling

Usage

mvnss_settings(
  n_mvnss_updates = 1,
  initial_bracket_width = 1,
  cov_update_interval = 1,
  bracket_limits = c(0, Inf),
  nugget_cooling = 0.9,
  nugget_step_size = NULL
)

Arguments

n_mvnss_updates

number of non-isotropoc hit-and-run updates.

initial_bracket_width

initial width of the slice bracket

cov_update_interval

how often the empirical covariance matrix should be updated

bracket_limits

limits for the slice bracket width, defaults to (0,Inf).

nugget_cooling

rate at which to cool the nugget, defaults to 0.9. Adaptation contributions are governed by a harmonic sequence: scale_constant/(iteration/step_size+1)^scale_cooling. The plot_adaptations function may be used to plot the adaptation factors.

nugget_step_size

increment for each iteration, defaults to 100/number of iterations.

Value

list with additional settings for hit and run slice sampling
