Release 2.7.0 imports posterior. We could use more posterior package functions. This would reduce possibility of having different implementations and thus reduce maintenance burden. Potential functions to replace

    • fft_next_good_size
    • autocovariance
  • part of do_psis_i
    • psis_smooth_tail
    • n_pareto
    • enough_tail_samples
  • ps_khat_threshold
  • pareto_smooth
    • .pareto_smooth_tail
    • as_one_logical
    • should_return_NA
    • is_constant
  • ess_tail
    • ess_quantile
    • .ess_quantile
    • .ess
    • .split_chains
