Consensus K-orthonormal basis (K-Procrustes mean)

Iteratively aligns bases, takes a weighted average, and retraction via K-orthonormalization until convergence.

Usage

dkge_consensus_basis_K(
  U_list,
  K,
  weights = NULL,
  Kroots = NULL,
  max_iter = 50,
  tol = 1e-06,
  allow_reflection = TRUE
)

Arguments

U_list

list of qxr K-orthonormal bases

K

qxq design kernel

weights

optional numeric weights (default equal)

Kroots

optional precomputed kernel roots

max_iter

maximum iterations

tol

convergence tolerance on 1 - mean principal cosines

allow_reflection

passed to alignment step

Value

list(U, iters, converged, gaps, scores)
