Usage

morie_spatial_voting_nonparametric_bootstrap(
  Z,
  scale_fn = "am",
  n_boot = 200L,
  seed = 42L
)

Arguments

Z

Perception matrix.

scale_fn

One of "am", "blackbox", "blackbox_t".

n_boot

Number of bootstrap replications.

seed

RNG seed.

Value

List with se_positions, boot_mean, ci_lower, ci_upper, n_boot.
