In lgspline: Lagrangian Multiplier Smoothing Splines for Smooth Function Estimation

Compute Predictions During Penalty Tuning

Description

Wrapper around matmult_block_diagonal for computing partition-wise predictions \mathbf{X}_{k} \boldsymbol{\beta}_{k} during penalty tuning.

Usage

.compute_tuning_predictions(
  X,
  B,
  K,
  parallel,
  cl,
  chunk_size,
  num_chunks,
  rem_chunks
)

Arguments

X	List; design matrices by partition.
B	List; coefficient vectors by partition.
K	Integer; number of interior knots.
parallel	Logical; use parallel computation.
cl	Parallel cluster object.
chunk_size, num_chunks, rem_chunks	Integer; parallel chunking parameters.

Value

List of prediction vectors, one per partition.
