Bootstrap inference for PLSC loadings — bootstrap_plsc • multivarious

Provides bootstrap ratios (mean / sd) for X and Y loadings to assess stability, mirroring common practice in Behavior PLSC.

Usage

bootstrap_plsc(
  x,
  X,
  Y,
  nboot = 500,
  comps = ncomp(x),
  seed = NULL,
  parallel = FALSE,
  epsilon = 1e-09,
  ...
)

Arguments

x: A fitted plsc object.
X: Original X block.
Y: Original Y block.
nboot: Number of bootstrap samples (default 500).
comps: Number of components to bootstrap (default: ncomp(x)).
seed: Optional integer seed for reproducibility.
parallel: Use future.apply for parallelization (default FALSE).
epsilon: Small positive constant to stabilize division for ratios.
...: Additional arguments (currently unused).
