landmark_warp: Landmark Warping

In wzhorton/warptk: Warping Toolkit

Description

Warps a list of curves by matching landmarks to provided template landmarks.

Usage

landmark_warp(
  y_list,
  feat_list,
  template_feats,
  niter = 1000,
  nburn = 1000,
  int_p = 20,
  asig = 0.1,
  bsig = 0.1,
  at = 0.1,
  bt = 0.1,
  progress = TRUE,
  debug = FALSE
)

Arguments

y_list	list of curves with equal length
feat_list	list of feature vectors with equal length
template_feats	a feature vector with length mathing those in feat_list
niter, nburn	MCMC iterations and burns. Total run time is the sum.
int_p	number of internal knots specified for the data curves
asig, bsig, at, bt	hyperparameters for inverse gamma priors on model variances
progress	logical; indicates whether or not to print percent progress.
debug	logical; stops function right before return and enters debug mode.

Value

a list of warped curves and an estimated mean curve. List elements are vectors with length matching the elements of y_list.
